Interstate 80 (I-80) is a part of the

US-30S
.

Construction of the

SR-58
and 121,205 vehicles using the freeway at the Spaghetti Bowl in Downtown Salt Lake City. Throughout the state, the highway is also known as the Purple Heart Trail.

Route description

Out of the 11 states which I-80 passes through, the 197.51-mile-long (317.86 km) segment in Utah is the fourth shortest. As part of the Interstate Highway System,[2] the entire route is listed on the National Highway System, a system of roads that are important to the nation's economy, defense, and mobility.[3]

Every year, the

Spaghetti Bowl in Downtown Salt Lake City.[4] Between 7 and 58 percent of the traffic recorded consisted of trucks.[5]
These counts are for the portion of the freeway in Utah.

Tooele County

The freeway enters Utah from Nevada in the city of Wendover on the edge of the Bonneville Salt Flats. The cities of West Wendover, Nevada, and Wendover are accessible by I-80's only business loop in Utah,[6] whose interchange is just south of Danger Cave.[7][8] The highway closely follows the historical routes of the Wendover Cut-off, Victory Highway,[9] and formerly Western Pacific Railroad's Feather River Route (now part of the Union Pacific Railroad Central Corridor) across the salt flats and the larger Great Salt Lake Desert.[10] Bonneville Speedway, home to many land speed records, is accessible from I-80.[11] In the middle of the salt flats is a concrete sculpture, Metaphor: The Tree of Utah, which stands just off the westbound carriageway of I-80, 30 miles (48 km) east of Wendover.[12]

Bounded on each sides by military training grounds,[13] the I-80 corridor is overflown by commercial airliners traveling west from Salt Lake City International Airport.[14] The freeway veers north around the Cedar Mountains in a small gap between them and the Lakeside Mountains. Further east, the highway passes the Stansbury Mountains, which are located in the Wasatch–Cache National Forest.[15] After the mountain ranges, the freeway arrives at the southern shore of the Great Salt Lake and closely follows the shore toward the western suburbs of Salt Lake City.[16] However, the historical routes from which the route of I-80 was derived were routed further from the lake, passing through the towns of Grantsville and Tooele; these communities are now served by SR-138 and SR-36, respectively.[7] It is in this section that I-80 reaches its lowest elevation in Utah, 4,203 feet (1,281 m) above sea level.[17] After an interchange with SR-36 at Lake Point, the highway crosses a bottleneck between the Oquirrh Mountains and the Great Salt Lake.

Salt Lake County

While traversing the neck, views can be had from I-80 of the lake and

tailings pond to the south. The Kennecott Utah Copper's Bingham Canyon Mine, which was once considered to be the largest open-pit copper mine, can be seen in the distance.[19] The 1,215-foot-tall (370 m) Kennecott Garfield Smelter Stack is one of the tallest freestanding structures in the United States.[20] Along this portion, the freeway passes the historical site of Saltair.[7]

Spaghetti Bowl in South Salt Lake

The freeway enters the

beltway around Salt Lake City. It continues through Parleys Canyon,[7] where the freeway joins the historical route of the Lincoln Highway.[23] Between the mouth of the canyon and the Summit County line, the route reenters the Wasatch National Forest.[18]

Summit County

Parleys Canyon carries I-80 up the eastern slope of the

Mormon leader who was asked to survey a new route across the mountains to replace the route through Emigration Canyon. Between 1848 and 1851, Pratt surveyed, completed, and operated the Golden Pass toll road through the canyon that today bears his name. Pratt had unsuccessfully solicited for $800 (equivalent to $22,801 in 2023[25]) to build the road and sold it for $1,500 (equivalent to $43,668 in 2023[25]).[26] On- and offramps for the Wyoming port-of-entry are located just within Utah.[7] In January 2014, UDOT introduced variable speed limits to I-80 in Parleys Canyon, allowing a speed limit between 35 mph (56 km/h) up to the normal 65 mph (105 km/h) depending on weather or traffic conditions.[27]

Beyond Parleys Summit lies

Echo Reservoir.[30] The freeway turns north upon reaching the Rockport Reservoir at Wanship[31] following the tributaries of the Weber River toward Echo Reservoir and Dam. Upon reaching Echo Canyon and the junction with the eastern terminus of the western section of I-84, the freeway follows the canyon east until it reaches the Wyoming state line near Evanston. I-80 forms the northeastern border between Rich and Summit counties.[32]

The portion through Echo Canyon follows the historical routes of the

US-30S, and the first transcontinental railroad.[33] A rest area in the canyon just east of the junction with I-84 features signs pointing out features that were obstacles for both the Mormon pioneers and the railroad construction workers, including Pulpit Rock,[34] which was partially demolished when the I-80 was built through the canyon.[35]

Victory Highway in Utah and Wendover Cut-off

I-80 follows the routes of two major auto trails through the state. In western Utah, I-80 follows the historical route of the Victory Highway from Wendover at the Nevada state line to the junction of US-40 near Park City. Throughout Utah, I-80 is signed as the modern route of the Lincoln Highway—except through Salt Lake City, where the Lincoln Highway is routed along SR-201 and Parley's Way. The route of the Lincoln Highway across Utah was generally derived from the route of the Pony Express and Central Overland Route. However, much of the original route of the Lincoln Highway west of Salt Lake City is inaccessible. The original route of the Lincoln Highway proceeded southwest from Tooele toward Ely, Nevada. This area is now used for military bases, such as the Dugway Proving Ground and Tooele Army Depot. The area was closed to the public when these bases were established. I-80 and US-93 are the modern signing of the Lincoln Highway between those two cities. East of Salt Lake City, I-80 closely parallels the original route of the Lincoln Highway.[36][37]

In 1926, much of the route covered by I-80, including Pratt's former toll road from the Nevada state line into Salt Lake City, was signed as US-40 then as US-30 to the Wyoming state line.

US-189.[42] By 1959, US-50 Alternate (US-50 Alt) was also routed along the western portion of I-80.[43]

Current road

The first Utah state route to have the number 80 is now known as SR-92, which was originally numbered SR-80 until the 1977 Utah state route renumbering. Previously, the freeway's legislative designation was SR-2.[44]

Promontory Summit, where the golden spike of the US's first transcontinental railroad was laid.[49]

The original designation of I-84, which begins at an interchange with I-80 in Echo, was I-80N. This designation was changed to I-84 in 1977 by the American Association of State Highway and Transportation Officials (AASHTO) despite objections from the Washington State Department of Transportation (WSDOT) and the Idaho Transportation Department (ITD) and with the support of UDOT and the Oregon Department of Transportation (ODOT). The legislative designation for this highway was SR-3 until the 1977 renumbering.[44]

Rebuilding of the first portions of I-80 began in October 1990 with a 1.4-mile-long (2.3 km) stretch near Redwood Road in Salt Lake City.[50] By 1991, UDOT estimated that the reconstruction of all federally funded highways in the state would cost up to $4.3 billion (equivalent to $8.58 billion in 2023[25]).[51]

Plans for the Spaghetti Bowl were announced in 1996. It was needed to accommodate traffic for the 2002 Winter Olympics being held in the city.[52] Most of the Spaghetti Bowl was open by November 2000; the remainder opened in early 2001.[53]

In 2002, the Utah State Legislature named the highway the Purple Heart trail,[54] in honor of wounded war veterans.[55]

Additional reconstruction work—which involved the replacement of most of the bridges along the route and the resurfacing and installation of sound barriers—was done on I-80 between the Spaghetti Bowl and Parleys Canyon from 2007 to 2008.[56]
