US 20

U.S. Route 20 (US 20) is an east–west US Highway spanning central Oregon, southern Idaho and Montana, central Wyoming, northern Nebraska, and northern Iowa in American Truck Simulator. The route is separated into four sections: The first section runs from US 101 in Newport to OR 201 in Ontario. The second section runs from US 26 and Can-Ada Road in Nampa to West Yellowstone. The third section runs from the eastern entrance of Yellowstone National Park to Casper. The fourth section runs from Casper to US 61 in Dubuque.

In real life, US 20 is the longest US route in the United States from Newport, Oregon to Boston, Massachusetts, a distance of 3365 miles (5415 km).

Course

US begins in Newport, OR, at its intersection with US 101. It crosses the Central Oregon Coast Range, where a Page & Price Paper mill and a Deepgrove logging site branch from the road, before entering the Willamette Valley, where it intersects with Interstate 5 at Albany. The highway then crosses the Cascade Range via Tombstone Pass, where another Deepgrove logging site is located, and descends past Black Butte to Bend, where it intersects with US 97. The 20 runs below Pilot Butte out of Bend and enters the scrublands of the Harney Basin, a northern extension of the Great Basin. Past the ghost town of Millican and the rest area at Brothers, passing below the Blue Mountains to the north, the highway reaches Riley, where US 395 begins a concurrency that ends north of Burns. The 20 proceeds past Buchanan and across the arid hills through Juntura, after which it runs along the Malhuer River through its gorge. The highway enters the Treasure Valley at Vale, where it intersects with the historic Oregon Trail, and proceeds across farmlands to its intersection with OR 201, where this segment ends, the 201 heading north to Ontario.

US 20 resumes at its intersection with N Can-Ada Road in the farmlands north of Nampa, ID, where it runs concurrent with US 26. At Eagle the highway intersects with ID-55, and shortly thereafter runs through downtown Boise, Idaho's capital and largest city. The 20 runs concurrent with Interstate 84 from Boise to Mountain Home, where it also breaks from the 26. Out of the Snake River Plain, the highway runs along the edge of the Danskin Mountains and the Mount Bennett Hills, along the way passing historical markers for Castle Rock and Goodale's Cutoff (an alternate route of the Oregon Trail that is roughly followed here). The highway then enters the Camas Prairie, where it intersects with ID-75, and soon after passes through the town of Carey, where it meets with US 26 and US 93. The three highways all run concurrent along the southern edge of the Pioneer Mountains, a range of the Northern Rocky Mountains, and pass along the northern boundary of Craters of the Moon National Monument and Preserve, an old volcano field that offers a viewpoint. At Arco the 93 breaks off, and the 20 and 26 run through the Snake River Plain, past the Idaho National Laboratory (a government lab complex specializing in nuclear energy), where US 26 soon after breaks away. After then running through the north of Idaho Falls, the highway heads north east and enters Montana.

From Idaho Falls, US 20 heads northeast through woodlands before it enters Island Park and crosses the river, Henrys Fork, three times before passing through Macks Inn. After passing through these areas, the 20 climbs the Targhee Pass and crosses the Continental Divide, where it then enters Montana. In Montana, US 20 passes through West Yellowstone, where it meets up with US 191 and US 287 before entering Yellowstone National Park, where its western half ends. US 20 resumes upon exiting Yellowstone National Park at Pahaska Tepee. The highway exits the mountains and runs along the northern shore of the Buffalo Bill Reservoir, which is followed by a scenic run through Shoshone Canyon. Leaving the gorge, the highway passes through Cody, and crosses the Bighorn Basin to Greybull.

At Greybull, US 20 splits from US 14, and heads south. After winding through the fertile basin to the west of the Bighorn Mountains, the highway runs through Thermopolis, a town surrounded by colorful buttes that is home to the world's largest mineral hot spring. Out of Thermopolis, the highway runs along the Bighorn River to the Wind River Canyon, at the mouth of which the Wind River becomes known as the Bighorn. The highway runs alongside the river and the railroad through this narrow, high-walled gorge, a scenic road that features a viewpoint. After passing through three rough-hewn tunnels, the highway leaves the gorge at the Boysen Dam and runs along the Boysen Reservoir to Shoshoni, now in the Wind River Basin, where it turns east, running concurrent with US 26. The highway sets off on a course across quiet, arid terrain, a route across the Casper Arch that features a rest area and three small scenery towns: Moneta, Hiland, and Powder River. The scenery takes a turn for the interesting at Hells Half Acre, a colorful patch of badlands that features a viewpoint and a dirt road that goes along the scarp's rim; this land of rugged, banded rock, being almost alien-looking, was used to represent the planet Klendathu in the 1997 film "Starship Troopers." Soon, having crossed the Casper Arch, the highway enters the Powder River Basin, and with it, the city of Casper. From here the highway runs concurrent with Interstate 25, a concurrency that ends at Orin, where there is a truck stop.

From Orin, US 20 continues east, passing through Lusk before reaching the Nebraska state line. The highway runs through the northern plains of Nebraska, passing through Chadron, Merriman, Valentine, Bassett, and O'Neill. After passing O'Neill, US 20 reaches a weigh station where the route diverges east from a US 275 concurrency. Further along, the route passes by another weigh station in Laurel before joining Interstate 129 and US 75 in the northeastern corner of the state before continuing into Iowa.

Special Routes

Idaho Falls business loop

U.S. Route 20 Business (US 20 Bus.) is a business loop of US 20 in Idaho Falls, Idaho. Its western terminus is at I-15 exit 118, and its eastern terminus at US 20 exit 310. In-game, the route's path is actually rendered in its entirety, but has been split into two separate sections, a west side running from I-15 to Yellowstone Avenue, concurrent with I-15 BL, and an east side running from US 26 to US 20.
