U.S. Route 13 (US 13) is a

divided highway with the exceptions of the segment through Wilmington and parts of the route in Claymont. Between the Maryland state line and Dover, US 13 serves as one of the main north–south routes across the Delmarva Peninsula. From Dover north to Tybouts Corner, the route is followed by the controlled-access Delaware Route 1 (DE 1) toll road, which crosses the route multiple times and has multiple interchanges with it. US 13 bypasses downtown Wilmington to the east before it heads northeast of the city parallel to Interstate 495 (I-495) and the Delaware River
to Claymont. US 13 is the longest numbered highway in the state of Delaware.

The portion of US 13 between Delmar and Dover was constructed as a state highway during the 1920s. Between Dover and Wilmington, the route was built as part of the cross-state DuPont Highway, which was completed in 1923 and improved transportation between northern and southern Delaware. North of Wilmington, what would become US 13 was originally built as the Philadelphia Pike in the 1820s and improved to a state highway by 1920. US 13 was designated through Delaware when the U.S. Highway System was created in 1926. The route was widened into a divided highway between Dover and Wilmington in the 1930s and between Delmar and Dover in the 1950s. US 13 was routed to bypass Dover in the 1950s. In 1970, US 13 was moved to its current alignment between Wilmington and Claymont on a bypass built in the 1930s. The portion of US 13 between Dover and Wilmington saw heavy traffic heading to the

Delaware Beaches
in the summer, which led to the construction of a freeway "Relief Route" parallel to US 13. This freeway was built as DE 1, which was completed in 2003. The construction of DE 1 necessitated the realignment of US 13 in two places.

Route description

US 13 enters Delaware from

divided highway called Sussex Highway, passing through rural areas and various cities and towns including Laurel, Seaford, Bridgeville, and Greenwood. The route continues into Kent County, where it becomes Dupont Highway and runs north through Harrington, Felton, and Camden. US 13 passes through Dover, where it heads through commercial areas. Past Dover, the route is paralleled by the controlled-access DE 1 toll road and comes to Smyrna, where it enters New Castle County. Here, US 13 continues north and crosses DE 1 multiple times, passing through Odessa. The route crosses the Chesapeake & Delaware Canal on the St. Georges Bridge before it runs concurrent with the DE 1 freeway between Wrangle Hill and Tybouts Corner. Upon splitting from DE 1, US 13 heads northeast through suburban areas along the multilane divided Dupont Highway, forming a concurrency with US 40 in the New Castle area. The route passes through the eastern part of Wilmington on city streets, including a one-way pair. Upon leaving Wilmington, US 13 becomes a multilane divided highway called Governor Printz Boulevard and runs northeast parallel to I-495 and the Delaware River to Claymont, where it follows Philadelphia Pike to the Pennsylvania state line.[3][4]

The section of US 13 south of Tybouts Corner serves as part of a primary

Smyrna Rest Area and in Seaford.[9] The route was designated as a Blue Star Memorial Highway between the Maryland state line and Dover in 1981 and between Dover and the Pennsylvania state line in 1998.[10]

Sussex County

US 13 northbound at western terminus of US 9 in Laurel

US 13 enters Delaware from

divided Sussex Highway, passing businesses. The route leaves Delmar and heads to the east of US 13 Dragway and Delaware International Speedway, running through wooded areas with some farm fields and development. The road crosses Dorothy Road/Whitesville Road at a superstreet intersection and continues through a mix of farmland and woodland before it reaches the town of Laurel. Here, US 13 heads past a few businesses and comes to a junction with DE 24. Following this, the route crosses Records Pond along Broad Creek and curves northwest. The road passes farm fields before it intersects the western terminus of US 9 and Georgetown Road near businesses. Past this intersection, US 13 leaves Laurel and runs through farms and woods with occasional development. The route heads north again and comes to a junction with DE 20 to the east of the town of Blades, at which point DE 20 turns north for a concurrency with US 13. The road crosses the Nanticoke River and heads into Seaford, where it passes businesses prior to heading across Williams Pond along Clear Brook. Past this, DE 20 splits from US 13 by heading to the west, while US 13 continues north through commercial areas.[3][4]

US 13 leaves Seaford and continues into rural areas with some development along the road. The road crosses Clear Brook east of Hearns Pond and the highway passes to the east of a residential development as Bridgeville Highway intersects the road. The road passes west of a

DE 404 Bus. head northwest into Bridgeville. At this point, US 13 becomes concurrent with DE 404 and the two routes pass through rural areas with some development to the east of Bridgeville. North of town, the road crosses Redden Road before meeting the northern terminus of US 13 Bus. at a southbound right-in/right-out intersection. A short distance later, DE 404 splits from US 13 by heading to the west. From here, the highway runs through a mix of farms and woods with some homes and businesses along the road. Upon reaching the town of Greenwood, the travel lanes of US 13 split to include businesses in the median. In Greenwood, the route crosses DE 16/DE 36. Upon departing Greenwood, the median narrows and the road heads back into rural areas.[3][4]

Kent County

US 13 continues north into

DE 10 Alt. near a few businesses on the eastern edge of the town of Woodside.[3][4]

US 13 northbound past the northern terminus of US 13 Alt. in Dover

Following this, US 13 runs through a mix of farms and woods, crossing

US 13 Alt. splits off to the northwest. Following this, the road passes to the west of Kent Acres. US 13 enters Dover at the Webbs Lane junction and comes to an at-grade intersection with the western terminus of the Puncheon Run Connector freeway, which heads east to provide access from northbound US 13 to the northbound direction of the DE 1 toll road and access from southbound DE 1 to US 13. Past this, the route runs northeast through business areas with some nearby homes, crossing Puncheon Run before reaching a junction with South State Street. The road curves north and passes over the St. Jones River, continuing past more commercial areas. US 13 intersects Martin Luther King Jr. Boulevard, which heads west to the Dover Green Historic District and Delaware Legislative Hall, a short distance before four-lane divided Bay Road merges into the northbound direction of US 13 at a directional intersection. Past Bay Road, US 13 widens to six lanes and continues northwest, crossing DE 8. At this intersection, the name of the road changes to North Dupont Highway. The route curves north and then northwest again as it is lined with several businesses. The roadway passes southwest of a park and ride lot located at a church south of the Lakeview Drive/Townsend Boulevard junction. North of Silver Lake, US 13 intersects the northern terminus of US 13 Alt. along with Leipsic Road east of the Delaware Agricultural Museum and Village, which is home to a park and ride lot. The highway runs between Dover Motor Speedway and the Bally's Dover hotel, casino, and harness racetrack to the northeast and Delaware State University and the university's Alumni Stadium to the southwest. The route passes to the southwest of the Dover Mall and the Delaware State Police Headquarters and Museum as it continues past more businesses. US 13 heads southwest of the Dover Campus of Wilmington University prior to coming to an intersection with Scarborough Road, which leads northeast to an interchange with DE 1 and southwest to DE 15 in the western part of Dover.[3][4]

Past Scarborough Road, the road narrows back to four lanes and passes northeast of the Terry Campus of Delaware Technical Community College. At the West Denneys Road intersection, US 13 leaves Dover and continues past residential and commercial development. To the east of the town of Cheswold, the route has a junction with DE 42 at Bishops Corner. Following this, the highway heads through a mix of residential development and farmland, crossing Alston Branch before curving north at the point it crosses the Leipsic River to the east of Garrisons Lake. US 13 passes more development and rural areas as it continues north and enters the town of Smyrna. Here, the name changes to South Dupont Boulevard and it runs past businesses as it reaches a ramp to the DE 1 toll road to the east. The road bends to the northwest as it heads to the east of a residential neighborhood and intersects Smyrna-Leipsic Road before passing west of the Belmont Hall State Conference Center. The route crosses Mill Creek to the east of Lake Como and runs through commercial areas in the eastern part of Smyrna. US 13 intersects DE 6, at which point the name becomes North Dupont Boulevard and DE 6 turns north for a concurrency. In the northern part of town, DE 6 splits from US 13 by heading southwest along with DE 300.[3][4]

New Castle County

US 13 northbound north of Odessa

US 13 crosses the

park and pool lot on the northwest corner of the intersection. From here, the road runs immediately to the east of DE 1, passing through Fieldsboro and running near residential subdivisions. DE 1 curves northwest away from US 13, with US 13 crossing the Appoquinimink River and heading into residential areas.[3][4]

The route passes west of a park and pool lot and enters the town of

St. Georges, a partial interchange provides access to and from the northbound direction of DE 1; the ramp from southbound DE 1 connects to US 13 by way of Lorewood Grove Road while there is a direct ramp from US 13 to northbound DE 1 at the Port Penn Road intersection in Biddles Corner that merges with the ramp from the northbound direction of the US 301 toll road to northbound DE 1. A right-in/right-out interchange connects to South Main Street northbound and Lorewood Grove Road southbound to provide access to South St. Georges.[3][4]

US 13 northbound past DE 1 and DE 71 in Tybouts Corner

US 13 heads across the

DE 9 Truck joins US 13. The road heads northeast through farmland with some businesses, passing to the east of the Buena Vista State Conference Center, before continuing into suburban residential and commercial development. US 13 crosses Army Creek and passes under Norfolk Southern's New Castle Secondary railroad line before it comes to a directional intersection with US 40 in State Road; this intersection has no access from northbound US 13 to westbound US 40.[3][4]

Split between US 13 southbound and US 40 westbound in State Road

At this point, US 40 joins US 13 and the roadway continues northeast as an eight-lane highway. The road runs through commercial areas, coming to an intersection with DE 273 in Hares Corner. At this point, DE 9 Truck splits from US 13/US 40 by heading east along DE 273. Past this intersection, US 13/US 40 becomes North Dupont Highway and passes between Wilmington Airport to the northwest and businesses to the southeast as it runs along the western border of New Castle for a short distance, reaching a partial cloverleaf interchange with the southern terminus of US 202 and DE 141 at the end of the airport property. Following this, the two routes narrow to six lanes, heading to the northwest of the Main Campus of Wilmington University and running through more commercial areas in Wilmington Manor. Along this stretch, the route gains a northbound combined right turn, bus, and bicycle lane. The road loses the northbound combined right turn, bus, and bicycle lane before passing over the Jack A. Markell Trail and reaching an interchange with I-295 in Farnhurst, where US 40 splits from US 13 by heading east along I-295 toward the Delaware Memorial Bridge. This interchange also provides access from US 13 to I-95 and I-495 via I-295. Past the I-295/US 40 interchange, the highway passes east of the Delaware Department of Health and Social Services' Herman M. Holloway Sr. Campus and regains a northbound combined right turn, bus, and bicycle lane as it heads through more commercial areas in Minquadale. US 13 loses the northbound combined right turn, bus, and bicycle lane again before it reaches an interchange with I-495, with access to and from the northbound lanes of I-495 and from the southbound lanes of I-495. Immediately after this interchange, US 13 Bus. splits from US 13 to head north into downtown Wilmington.[3][4]

Brandywine Creek on four-lane undivided Northeast Boulevard. Past the bridge, the route intersects East 12th Street and continues through urban residential and business areas as a four-lane divided highway.[3][4]

US 13 leaves Wilmington and runs east through commercial areas, with the median turning into a

Stoney Creek and passes through Holly Oak before it heads across Perkins Run and reaches Claymont. Along this stretch, there are emergency vehicle ramps connecting US 13 and I-495 in Holly Oak and Claymont. In Claymont, the route curves northwest away from I-495 and the Delaware River, passing homes before it intersects the northern terminus of US 13 Bus. Here, US 13 turns northeast onto four-lane undivided Philadelphia Pike and runs through commercial areas, passing to the northwest of Archmere Academy. The route has an interchange with I-495, at which point it becomes a divided highway, before it loses the median as it enters a mix of development and empty space, passing north of the Claymont station on SEPTA's Wilmington/Newark Line that runs along the Northeast Corridor. US 13 turns into a divided highway and crosses Naamans Creek before reaching an intersection with the eastern terminus of DE 92 south of the Robinson House. Past this, the road becomes undivided and crosses under the Northeast Corridor, gaining a median briefly as it passes under the railroad line. From here, the route heads into Sunoco's Marcus Hook Industrial Complex. US 13 continues into Pennsylvania, where it runs through more of the industrial complex in the borough of Marcus Hook.[3][4]

Rest area

Smyrna Rest Area

The Smyrna Rest Area (officially the Chauncey O. Simpson Memorial Rest Area) is a

picnic area, a pavilion, and a park and ride lot. Also located at the Smyrna Rest Area is the Delaware Highway Memorial Garden, which consists of a path with bricks bearing the names of people who died along roads in Delaware.[12] The path serves as an alternative to roadside memorials, which are illegal in Delaware for safety reasons.[13] The site of the Smyrna Rest Area was originally established as a picnic area in 1937 and was expanded over the years. The current rest area building opened on November 18, 1991.[12]

History

Predecessor roads

Before the numbering of the U.S. Highway System, there were many roads that ran north–south across Delaware along the rough alignment of the present route. In the 18th century, the King's Highway ran between Dover and Wilmington; south of Dover it continued southeast toward Lewes. By the later part of that century, a post road ran from Horn Town, Virginia, north across the Delmarva Peninsula. The road ran between Dover and Wilmington, where it continued northeast to the Pennsylvania border and headed toward Philadelphia.[14] In 1813, the Wilmington and Philadelphia Turnpike Company was chartered to build a turnpike running from the Brandywine Bridge in Wilmington northeast to the Pennsylvania border, where the roadway would continue to Philadelphia. A 3.75-mile (6.04 km) long portion of the road near Wilmington was finished in 1816 with the remainder completed in 1823.[15] With the Federal Aid Road Act of 1916, the Philadelphia Pike was to be improved by the state.[16] The Philadelphia Pike was upgraded to a state highway by 1920.[17] The Philadelphia Pike was designated a branch of Lincoln Highway[18] and part of the Capitol Trail[19] in the 1910s, which continued west of Wilmington to Newark and the Maryland border along the present-day DE 2 corridor.[20]

Construction of state highways

US 13 northbound past DE 10 in Camden

The portion of US 13 between Dover and Wilmington was built as part of the DuPont Highway. The DuPont Highway was proposed in 1908 by

Thomas Coleman DuPont as a modern road that was to run from Selbyville north to Wilmington as part of a philanthropic measure. This roadway was planned to improve travel and bring economic development to Kent and Sussex counties. The DuPont Highway was to be modeled after the great boulevards of Europe and was to have a 200-foot (61 m) wide right-of-way consisting of a 40-foot (12 m) wide roadway for automobiles flanked by dual trolley lines, 30-foot (9.1 m) wide roadways for heavy vehicles, 15-foot (4.6 m) wide unpaved roadways for horses, and sidewalks. Utilities were to be buried underground below the horse roadways. The highway was also to include agricultural experimental stations and monuments for future surveying. Trolley revenues would help pay for the construction of the roadway. After portions of the DuPont Highway were built, these portions were planned to be turned over to the state at no charge.[21]

In 1911, the Coleman DuPont Road, Inc., was established and construction on the highway began.[22] By 1912, construction was interrupted by litigation challenging both the constitutionality of the law establishing the road building corporation and the need for DuPont to acquire such a large right-of-way.[23] DuPont would narrow the proposed right-of-way to 100 feet (30 m) in order to compromise with opponents of the highway in addition to offering landowners whose properties were affected by the highway five times the assessed value of the land five years after the highway was completed.[22] The DuPont Highway would end up being built on a 60-foot (18 m) alignment with a 32-foot (9.8 m) wide roadway.[24] The length of the DuPont Highway between Selbyville and Wilmington was completed in 1923, with one of the final portions to be completed at the Drawyers Creek north of Odessa. A ceremony marking the completion of the highway was held in Dover on July 2, 1924.[25] The completion of the DuPont Highway improved transportation between northern and southern Delaware and would lead to the expansion of state highways in Delaware.[26]

Work also took place on constructing a state highway running from the Maryland border in Delmar north to Dover. By 1920, most of the highway in Sussex County had been completed with the exceptions of a portion north of Laurel and a portion north of Bridgeville. In Kent County, the state highway was completed between the Sussex County border and Farmington. The portion between Farmington and Woodside was under contract by 1920 while the portion between Woodside and Dover was under proposal.[17] By 1924, the entire length of the state highway between Delmar and Dover was completed.[27] A bascule bridge over the Nanticoke River in Seaford was completed in March 1925.[28] In 1925, recommendations were made to improve the South Market Street Causeway over the Christina River in Wilmington, which included a new bridge over the river.[28] Construction on the drawbridge began in May 1926.[29] In 1927, the new drawbridge, the four-lane South Market Street Bridge, opened over the Christina River on South Market Street in Wilmington, replacing a previous drawbridge that was only two lanes wide.[30]

With the proposal of the U.S. Highway System in 1925, US 13 was planned as one of three routes to pass through Delaware, running from the Maryland border in Delmar via Dover and Wilmington to the Pennsylvania border in Claymont.[28] US 13 was designated on November 11, 1926.[2] US 13 followed the Cape Charles Route between the Maryland border in Delmar and Dover, the DuPont Highway between Dover and Wilmington, Market Street through Wilmington, and the Philadelphia Pike between Wilmington and the Pennsylvania border in Claymont.[31] Between the Maryland border and US 40 (now DE 273) in Hares Corner, US 13 was part of the Ocean Highway, an Atlantic coastal highway stretching from Jacksonville, Florida, north to New Brunswick, New Jersey, that served as the quickest route between the New York City area and Florida before the introduction of the Interstate Highway System. US 13 is one of only four U.S. Routes that form the highway and Delaware was one of the states that participated in the highway's formation.[32] US 13 originally passed through Dover on State Street from Coopers Corner south of Dover to north of Silver Lake.[33] In 1930, US 13 was rerouted to follow a reconstructed Governors Avenue through Dover, with US 113 extended north along State Street from its previous northern terminus at Coopers Corner to end at US 13 at the intersection of Governors Avenue and State Street south of Silver Lake.[34]

Widening and improvements

US 13 northbound/US 40 eastbound at DE 273 in New Castle

The portion of the DuPont Highway between Dover and Wilmington saw increased traffic from connecting interstate roads and summer travelers, prompting the Delaware State Highway Department (DSHD) to consider widening the highway in 1925.[28] A year later, the department suggested the Philadelphia Pike be widened along with the DuPont Highway between State Road and Wilmington. This proposal included widening the bridge over a Pennsylvania Railroad line (now the Jack A. Markell Trail) in Farnhurst that was built in 1902.[29] US 13 was widened to four lanes between State Road and Wilmington and between Shellpot Park and Bellevue Quarry along the Philadelphia Pike in 1927.[25][30] The same year, the department recommended expanding the road between St. Georges and State Road into a divided highway.[30] In 1928, the widening of Philadelphia Pike was completed.[35] In 1929, the portion of the highway between St. Georges and State Road was widened into a divided highway.[25][36] The department recommended widening the part of US 13 between Delmar and Dover in 1930 as it was one of the main routes across the Delmarva Peninsula. In addition, plans began to widen the route into a divided highway between Drawyers Creek north of Odessa and St. Georges.[34] The divided highway portion of US 13 between Drawyers Creek and St. Georges was completed in September 1931. Also, work on widening the route to a divided highway between Fieldsboro and Drawyers Creek and from State Road to Wilmington began. The same year, recommendations began to extend the divided highway portion of US 13 south to Dover.[37]

US 13 northbound past DE 12 in Felton

In 1932, the portion of US 13 between Felton and Dover was widened. In addition, the divided highway between Reynolds' Corner and Drawyers Creek was completed in September and work began on widening US 13 into a divided highway between Smyrna and Reynolds' Corner. The completion of the divided highway between State Road and Wilmington was slated for summer 1933. This widening project included widening the bridge over the Pennsylvania Railroad in Farnhurst.[38] In 1933, the divided highway portion of US 13 was extended south to Smyrna while the portion between Dover and Smyrna was under contract. The same year, the remainder of US 13 south of Dover was widened.[39] The divided highway portion between Dover and Smyrna was finished on September 22, 1934, marking the completion of widening US 13 between Dover and Wilmington into a divided highway.[40] At the time, US 13 between Dover and Wilmington was the best superhighway and the longest stretch of divided highway in the world.[41]

In 1937, the narrow crossing of Silver Lake along State Street in Dover was replaced with a new, wider bridge.

Reading Railroad (now abandoned) and the Pennsylvania Railroad (now Norfolk Southern's Shellpot Secondary) on South Market Street in Wilmington was eliminated with the opening of a bridge over the railroad tracks.[43] On January 10, 1939, the S.S. Waukegan struck and destroyed the bridge carrying US 13 over the Chesapeake & Delaware Canal in St. Georges, killing the bridge tender.[44][45] The destruction of the bridge led to detours for US 13 along smaller roads. Plans were made to construct a high-level crossing of the canal.[46] Work on acquiring the right-of-way for the new bridge took place in 1940.[47] Construction of the bridge occurred in 1941.[48] The replacement steel truss St. Georges Bridge over the canal opened on January 31, 1942. This bridge was the first four-lane crossing of the Chesapeake & Delaware Canal.[45]

In 1950, recommendations were made by the chief engineer of the DSHD to widen US 13 into a divided highway between Delmar and Dover.

US 13 Alt. (now US 13 Bus.) while US 13 Alt. between Delmar and Hearne's Mill was decommissioned.[57]

US 13 northbound/US 40 eastbound at US 202/DE 141 interchange in Wilmington Manor

The alignment of US 13 in Wilmington has been shifted multiple times to improve traffic flow. By 1932, US 13 was split into the one-way pair of French Street northbound and Market Street southbound in the downtown area.[58] Both directions of the route was shifted to use French Street by 1936.[59] In 1952, a new bridge over the Christina River, the Walnut Street Bridge, was proposed to link Walnut Street in the downtown area with the Dupont Parkway section of US 13 south of the city. Under this plan, the Walnut Street Bridge would be used for northbound traffic while the South Market Street Bridge would be used for southbound traffic.[50] By this time, US 13 was routed on a one-way pair in the downtown area, using Walnut Street northbound and French Street southbound.[51] A year later, the Walnut Street Bridge project was under contract.[52] Construction on the project began in 1955.[54] Construction of the Walnut Street Extension, which included the drawbridge, approach roads, and a new bridge under the Pennsylvania Railroad, now Amtrak's Northeast Corridor, was completed in 1957. As a result, US 13 was split into the one-way pair of South Walnut Street northbound and South Market Street southbound between the south end of the city and downtown.[57][60]

Construction on an interchange with the Delaware Memorial Bridge approach at Farnhurst began on July 12, 1950.

Delaware Turnpike (I-95) that opened on November 14, 1963.[63] In 1954, there were plans to replace the intersection with DE 41/DE 141 in Basin Corner with a modified cloverleaf interchange in an effort to reduce traffic congestion.[53] Construction on the interchange began in September of that year.[54] The interchange between US 13/US 40/US 202 and DE 41/DE 141 was completed in 1956.[56][57] Plans were made to widen the Philadelphia Pike to a four-lane road between Bellevue Road and Claymont in 1954.[53] The widening project was completed in 1956.[56]

In 1961, the concrete bridge carrying southbound US 13 over the Drawyer Creek north of Odessa was closed due to deterioration from the tidal waters of the creek, with plans for a new bridge made.[64] Two years later, the southbound lanes were moved to the new bridge over the creek, following a straighter alignment.[65]

Bypasses of Dover and Wilmington

US 13 northbound past DE 3 in Edgemoor

Plans were made in 1918 for a bypass to the east of downtown Wilmington for through traffic, avoiding Market Street. The bypass would utilize Heald Street, Church and Spruce streets, and would construct Northeast Boulevard heading northeast from the Eleventh Street Bridge.

US 13 Alt. in 1939.[67] In 1939, construction was authorized to widen Governor Printz Boulevard into a divided highway.[46] The widening of the road to a divided highway was completed in 1940.[47] In 1942, a bridge was completed on Heald Street that eliminated the grade crossing with a Pennsylvania Railroad line.[68] US 13 Alt. was widened to four lanes between 11th Street and 30th Street in Wilmington in 1956.[56] In 1970, US 13 was rerouted to bypass downtown Wilmington on the US 13 Alt. alignment while US 13 Bus. was designated onto the former US 13 alignment from the southern border of Wilmington north to Claymont.[69]

In 1935, the portion of present-day US 13 between Bay Road and North State Street was built as part of a realigned US 113.

US 113 Alt. to follow the route between South State Street and US 113.[71][72] US 113 Alt. was removed from US 13 in 2004 as part of the truncation of US 113 from Dover to Milford.[73]

Relief Route

US 13 northbound approaching the split with DE 1 northbound in Tybouts Corner

Between 1958 and 1971, studies were conducted for a bypass of the segment of US 13 through Dover along with a connector between Dover and

Delaware Beaches in the summer.[77] Prior to the beginning of construction, an archaeological survey was conducted along the proposed route of the freeway in 1986.[78] The same year, plans were unveiled for the route, which would begin at US 113 south of Dover and head north to US 13 in Tybouts Corner. The Relief Route would cross US 13 several times, passing to the east of Dover and Smyrna and to the west of Odessa.[77] The US 13 Relief Route was designated DE 1 in 1988, keeping US 13 on its original alignment. DE 1 was extended north from Milford to Tybouts Corner in 1988, following US 13 between US 113 in Dover and Tybouts Corner.[79][80]

As part of building DE 1, the Puncheon Run Connector was proposed to provide a connection between DE 1 and US 13 in the southern part of Dover. The original plan for the connector in 1987 called for upgrading US 13 into a freeway from Woodside north to Dover, with interchanges at DE 10 in Camden and Webbs Lane in Dover. In 1992, plans for the freeway upgrade to US 13 between Woodside and Dover were dropped.[81] On December 21, 1993, DE 1 was completed between US 113 at Dover Air Force Base and US 13 north of Smyrna, with DE 1 rerouted off US 13 between Dover and Smyrna.[82][83]

Former divided highway alignment of US 13 near Delaware City that was bypassed when DE 1 was built and US 13 rerouted to follow DE 1. The southbound lanes serve as two-lane undivided Old South Dupont Highway while the northbound lanes are abandoned.

In December 1995, the section of DE 1 between US 13 in St. Georges and US 13 in Tybouts Corner opened, which included the Chesapeake & Delaware Canal Bridge (now called the Senator William V. Roth Jr. Bridge).[84][85] Following the completion of this segment, DE 1 was rerouted off the surface alignment of US 13 that crossed the St. Georges Bridge.[85] In addition, US 13 was rerouted to follow the new DE 1 between the DE 72 interchange and Tybouts Corner.[85][86] Construction of the new DE 1 had severed US 13 south of Tybouts Corner, with part of the former alignment north of the DE 7 intersection becoming a two-lane road called Old South Dupont Highway using the southbound lanes, with the northbound lanes abandoned, while the section south of there became an extended DE 7 to the intersection with US 13 and DE 72.[85] In building DE 1 across the Chesapeake & Delaware Canal, there were initially plans to demolish the aging St. Georges Bridge that carried US 13 over the canal. The plan drew concerns from residents in St. Georges who feared the community would be split in half. The St. Georges Bridge was instead kept and was refurbished. A southbound exit and northbound entrance at US 13 south of the Chesapeake & Delaware Canal Bridge along DE 1 was built as required by federal legislation that gave the state $115 million toward construction of the new canal bridge.[87]

The segment of DE 1 between US 13 south of Odessa and US 13 in St. Georges opened in November 1999.[74][88] DE 1 was subsequently rerouted off US 13 between those two points.[88] The construction of the final segment of DE 1 between Smyrna and Odessa resulted in a portion of US 13 south of Odessa being shifted further east as DE 1 would be built on top of the road. A service road would serve properties on the southbound side of US 13.[89] In October 2001, northbound US 13 was realigned to the new alignment south of Odessa in order to build DE 1 in that area.[90] In May 2002, US 13 was shifted to a new southbound alignment south of Odessa, with the former portion of the route in that area becoming a service road known as Harris Road.[91][92] The final section of DE 1 between Smyrna and Odessa opened on May 21, 2003.[93] As a result, DE 1 was moved off US 13 between Smyrna and Odessa.[94]

21st century

US 13 northbound in Camden

In June 2007, a $15 million project began that realigned the intersection between US 13 and DE 404/US 13 Bus./DE 404 Bus. in Bridgeville from a skewed intersection to a perpendicular intersection and built service roads on both sides of US 13. The project was intended to improve safety at the intersection, which saw a high accident rate due to its design. Work on the project was completed on May 21, 2009, with DelDOT secretary Carolann Wicks and President of Commissioners for the Town of Bridgeville William Jefferson in attendance at a ceremony.[95][96] On February 29, 2016, construction began on a superstreet intersection at DE 30 (Dorothy Road/Whitesville Road); this project was completed on May 19 of that year.[97]

On December 24, 2018, the ramp from US 13 to northbound DE 1 in St. Georges moved further south to the Biddles Corner mainline toll plaza as part of the project constructing the US 301 toll road.[98][99]

There are plans to widen the portion of US 13 from Lochmeath Way in Camden north to the Puncheon Run Connector in Dover from four lanes to six lanes.[100]
