New Orleans, Louisiana, and is connected to Interstate 10).
U.S. Numbered Highways are the original interstate highways, dating back to 1926. U.S. Highways are also numbered in a grid: even numbered for east–west routes (with the lowest numbers along Canada) and odd numbered for north–south routes (with the lowest numbers along the Atlantic Ocean). Three-digit highways, also known as "child routes," are branches off their main one- or two-digit "parents" (for example, U.S. Route 202 is a branch of U.S. Route 2). However, US 101, rather than a "child" of US 1, is considered a "mainline" U.S. Route.

State highways are the next level in the hierarchy. Each state and territory has its own system for numbering highways, some more systematic than others. Each state also has its own design for its highway markers; the number in a circle is the default sign, but many choose a different design connected to the state, such as an outline of the state with the number inside. Many states also operate a system of county highways.

Interstate 675 (I-675) is an auxiliary Interstate Highway in the US state of Michigan. The freeway is a 7.7-mile-long (12.4 km) loop route through downtown Saginaw, as I-75 passes on the east side of the city. I-675 is also a state trunkline highway that provided a bypass of the former drawbridge carrying I-75 and US Highway 23 (US 23) across the Saginaw River. Construction of I-675 started in 1969 and the freeway opened in 1971. Since then, sections near downtown were reconstructed between 2009 and 2011 to update one of the freeway's interchanges and rebuild the bridge over the Saginaw River. (Full article...) -
Illinois State Toll Highway Authority (ISTHA). I-355 runs from I-80 in New Lenox north to I-290 in Itasca, a distance of 32.5 miles (52.3 km). With the exception of a four-mile (6.4 km) expansion in 2009, from U.S. Route 34 (US 34, Ogden Avenue) to 75th Street, the highway is six lanes wide for its entire length.)
The tollway authority opened I-355 as the North–South Tollway in 1989 to ease congestion on Illinois Route 53 (IL 53), a parallel two-lane state highway in central DuPage County. Initially, I-355 ran from I-55 north to I-290. The new highway helped cut travel times for commuters traveling north and south in the county. According to commercial real estate developers at the time, the new tollway also opened the western suburbs of Chicago to commercial and industrial development. (Full article... -

U.S. Route. Portions of I-70 were constructed in areas where previously there were no paved roads. Because it was built over an entirely new route, I-70 has many features that are unique in the Interstate Highway System. For example, the 110 miles (180 km) between Green River and Salina makes up the longest distance anywhere in the Interstate Highway System with no motorist services. This same piece is noted as the longest highway in the United States built over a completely new route since the Alaska Highway, and the longest piece of Interstate Highway to open at a given time. The construction of the Utah portion of I-70 is listed as one of the engineering marvels of the Interstate Highway System. (Full article...)

Lake Superior Circle Tour. M-28 also carries two memorial highway designations along its route.)
Throughout its course across the Upper Peninsula, M-28 passes through forested woodlands, bog swamps, urbanized areas, and along the Lake Superior shoreline. Sections of roadway cross the Ottawa National Forest and both units of the Hiawatha National Forest. Some of the other landmarks accessible from M-28 include the Seney Stretch, Seney National Wildlife Refuge and several historic bridges. (Full article... -
Lake Michigan Circle Tour (LMCT) moniker. Four bridges used by the highway have been recognized for their historic character as well.)
The first highways along the route of the modern US 31 corridor were the West Michigan Pike, an auto trail from 1913, and later a pair of state trunklines (the original M-11 and M-58) in 1919. These state highways were redesignated US 31 on November 11, 1926, when the US Highway System was approved. Since then, the highway has been realigned in places. The highway crossed the Straits of Mackinac by ferry for about a decade in the 1920s and 1930s before the Mackinac Bridge was built, connecting to US 2 north of St. Ignace. Later, sections were converted into freeways starting in the 1950s. These segments opened through the subsequent decades with the last one opening in 2022. Future plans by the Michigan Department of Transportation (MDOT) include a bypass of Grand Haven. (Full article... -
Interstate 40 (I-40) is part of the Interstate Highway System that runs 2,556.61 miles (4,114.46 km) from Barstow, California, to Wilmington, North Carolina. The highway crosses Tennessee from west to east, from the Mississippi River at the Arkansas border to the Blue Ridge Mountains at the North Carolina border. At 455.28 miles (732.70 km), the Tennessee segment of I-40 is the longest of the eight states through which it passes and the state's longest Interstate Highway.
I-40 passes through Tennessee's three largest cities—Memphis, Nashville, and Knoxville—and serves the Great Smoky Mountains National Park, the most-visited national park in the United States. It crosses all of Tennessee's physiographic regions and Grand Divisions—the Mississippi embayment and Gulf Coastal Plain in West Tennessee, the Highland Rim and Nashville Basin in Middle Tennessee, and the Cumberland Plateau, Cumberland Mountains, Ridge-and-Valley Appalachians, and Blue Ridge Mountains in East Tennessee. Landscapes on the route vary from flat, level plains and swamplands in the west to irregular rolling hills, cavernous limestone bluffs, and deep river gorges in the central part of the state, to plateau tablelands, broad river valleys, narrow mountain passes, and mountain peaks in the east.

U.S. Route 40 Alternate (US 40 Alt.) near Cumberland. Between Westernport and Frostburg, it is known as Georges Creek Road, and from Frostburg to Cumberland it is known as Mount Savage Road. Like the majority of Maryland state highways, MD 36 is maintained by the Maryland State Highway Administration (MDSHA).)
MD 36 serves as the main road through the Georges Creek Valley, a region which is historically known for coal mining, and has been designated by MDSHA as part of the Coal Heritage Scenic Byway. MD 36 is the main road connecting the towns of Westernport, Lonaconing, and Midland in southwestern Allegany County, as well as Frostburg, Mount Savage, and Corriganville in northwestern Allegany County.

Interstate 182 (I-182) is an east–west auxiliary Interstate Highway in the U.S. state of Washington. It serves as a connector from I-82 to the Tri-Cities region that crosses the Columbia River on the Interstate 182 Bridge between Richland and Pasco. I-182 is 15 miles (24 km) long and entirely concurrent with U.S. Route 12 (US 12); it also intersects State Route 240 (SR 240) and US 395.
Business leaders in the Tri-Cities began lobbying for a freeway in 1958 after early alignments for I-82 were routed away from the area. I-182 was created by the federal government in 1969 as a compromise to the routing dispute, which allowed for direct access to the Tri-Cities and a bypass for other traffic. The new freeway would also include construction of a bridge between Richland and Pasco, proposed since the 1940s at the site of an earlier cable ferry that ran until 1931. (Full article...) -
business loop off US 41 and M-28 in Marquette, Michigan, along Washington and Front streets. The streets serve the downtown area of Marquette and are bordered by several commercial properties and businesses. Those two streets originate with the early founding of the city in the middle of the 19th century. Jurisdiction over them was transferred to the city as part of a highway swap that resulted in the decommissioning of the trunkline in 2005. It was also previously co-designated Bus. M-28, mirroring the Bus. US 41/Bus. M-28 designation previously used along Bus. M-28 in Ishpeming and Negaunee. Washington and Front streets had been a part of the state highway system since the 1910s, and a part of the United States Numbered Highway System since 1926. The business loop designation dates back to the 1960s and was removed in 2005. (Full article...)

business loop of Interstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of US Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with US 93 Alternate (US 93 Alt), and the entire portion in Utah is coterminous with Utah State Route 58 (SR-58). The Nevada Department of Transportation (NDOT) applied for the business loop designation in the early 1980s, but the designation has never been approved; nevertheless, signs are posted in both states. Between July 1976 and 1993, I-80 Bus was concurrent with Nevada State Route 224 (SR 224) in Nevada. (Full article...)

State Route 37. It is 57.46 miles (92.47 km) long. State Route 161 passes through the northern parts of Columbus, Ohio's state capital, and a variety of towns including Plain City, Dublin, and New Albany.)
The route was established in 1924 to connect Plain City and Dublin. It was later expanded to cover Mutual and Granville. Parts of SR 161 in Dublin and New Albany were upgraded to a freeway in 1969 and 1997. (Full article... -
Route 24 is a 10.42-mile (16.77 km) freeway in New Jersey, United States, that begins at a junction with Interstate 287 (I-287) in Hanover Township in Morris County, passes southeast through Essex County, and ends at a junction with I-78 in Springfield Township in Union County.
The route was created in 1927 to run from Phillipsburg to Newark, replacing pre-1927 Route 12 from Phillipsburg to Penwell and Pre-1927 Route 5 from Morristown to Newark. The route was extended west to the new Easton–Phillipsburg Toll Bridge in 1938 but was cut back to U.S. Route 22 (US 22) in the eastern part of Phillipsburg in 1953. The western terminus was cut back further around 1970 to Hackettstown with the route west of there becoming part of Route 57. The freeway alignment of Route 24 between the John F. Kennedy Parkway and I-78 was completed in 1976. (Full article...) -

State Route 117 (SR 117) is a short, 1.40-mile (2.25 km) long state highway located entirely within Port Angeles, the county seat of Clallam County, in the U.S. state of Washington. The short roadway, named the Tumwater Truck Route, serves the waterfront of Port Angeles and intersects two streets and crosses under another street on a short bridge. Beginning at an interchange with U.S. Route 101 (US 101), the highway travels northeast to terminate at Marine Drive. SR 117 was first established in 1991, but a road parallel to the current roadway had existed since 1966. (Full article...) -
Maryland Route 194 (MD 194) is a state highway in the U.S. state of Maryland. The state highway runs 23.87 miles (38.42 km) from MD 26 in Ceresville north to the Pennsylvania state line near Taneytown, where the highway continues as Pennsylvania Route 194 (PA 194) toward Hanover. MD 194 is the main highway between Frederick and Hanover; the state highway connects the towns of Walkersville and Woodsboro in northeastern Frederick County with Keymar and Taneytown in northwestern Carroll County. MD 194 was blazed as a migration route in the 18th century and a pair of turnpikes in Frederick County in the 19th century, one of which was the last private toll road in Maryland. The state highway, which was originally designated MD 71, was built as a modern highway in Frederick County in the mid-1920s and constructed as Francis Scott Key Highway in Carroll County in the late 1920s and early 1930s. MD 194 received its modern route number in 1956 as part of a three-route number swap. The state highway's bypasses of Walkersville and Woodsboro opened in the early 1980s and mid-1990s, respectively.

NY 40 west of Cato and New York State Route 37 from Cato to Baldwinsville. From Liverpool to Syracuse, modern NY 370 was initially part of NY 57, a route that continued north from Liverpool to Oswego. That route was eliminated in 1982, at which time NY 370 was extended eastward to Syracuse over NY 57's former routing. Other minor changes, namely a series of realignments west of Victory, have also occurred since NY 370 was assigned. (Full article...)

State Route 24 (SR 24) is a state highway in the south-central region of Washington, in the United States. It travels 79 miles (127 km) from Yakima to Othello, across a portion of the Columbia Plateau. The highway crosses the Columbia River on the Vernita Bridge, located near the Hanford Site. SR 24 terminates to the west at an interchange with Interstate 82 (I-82) in Yakima and to the east at SR 26 in Othello.
The highway was added to the state highway system in 1937 as Secondary State Highway 11A (SSH 11A), composed of several county-built gravel roads from Yakima to Connell, with a ferry crossing at Hanford. The Hanford section of SSH 11A was closed in 1943 due to wartime activities at the Hanford Nuclear Reservation, forcing the state government to relocate the highway to the north side of the Columbia River. The new highway opened in 1961 and was supplanted by the new Vernita toll bridge in 1965. During the 1964 state highway renumbering, SR 24 replaced most of SSH 11A and was rerouted to a terminus in Othello. (Full article...) -

NY 37 was assigned in 1930 to the portion of the Theodore Roosevelt International Highway between Redwood and Malone as well as to a previously unnumbered roadway between Watertown and Redwood. The Redwood–Malone portion was originally part of NY 3 when the first set of posted routes in New York were assigned in 1924. NY 37 has since been rerouted in areas, primarily near Ogdensburg and Massena. (Full article... -
US 264. US 64 and I-87 are concurrent with I-440 along the remainder of the road's southwesterly routing. Exit 16 is the last exit on I-440, where I-440 splits to join either I-40 eastbound or I-40 westbound.)
The Raleigh Beltline was formed from a number of highway segments, the earliest of which had been in place since 1959. The loop was completed in 1984 under multiple route designations. To avoid confusion along the beltline, I-440 was routed along the entirety of the beltline and shared a concurrency with its parent, I-40, along the loop's southern segment (Tom Bradshaw Freeway). In 2008, the I-440 designation was removed from the section of I-40/US 64 in southeast Raleigh. The highway's original "inner" and "outer" designations were also removed and replaced with compass directions (e.g., east/west). The easternmost two miles (3.2 km) of the I-440 was rebuilt in 2015 as part of the larger widening project along I-40 in South Raleigh, while the westernmost four miles (6.4 km), the oldest segment and one which is not up to Interstate standards, is currently undergoing widening and upgrading and is scheduled to be complete by 2023.

NY 30. In 1927, it also became part of US 4, which initially overlapped NY 30 from Glens Falls to Whitehall. In the 1930 renumbering of state highways in New York, NY 30 was reassigned elsewhere while US 4 was rerouted to bypass Glens Falls to the east. As a result, Lower Warren Street and River Street became part of NY 32B. (Full article...)
