U.S. Route 287 (US287) is a north–south (physically northwest–southeast) United States highway. At long, it is the second longest three-digit U.S. Route, behind US 281. The highway is broken into two segments by Yellowstone National Park, where unnumbered park roads serve as a connector.

The highway's northern terminus is in Choteau, Montana, south of the Canadian border, at an intersection with US 89. Its southern terminus (as well as those of US 69 and US 96) is in Port Arthur, Texas at an intersection with State Highway 87 (SH87), up the Sabine River from the Gulf of Mexico. It intersects its parent route US 87 twice, overlapping it from Amarillo to Dumas, Texas, and then crossing it in Denver, Colorado.

Route description

Texas

US287 originates at its southern terminus in Port Arthur as a branch of SH 87. From Port Arthur, US287 runs concurrently with US 69 and US 96 to Lumberton, where US96 diverges to the northeast and the co-signed US287/US69 continues northwesterly until US287 and US69 diverge in Woodville. Continuing northwesterly, US287 merges with Interstate 45 (I-45) in Corsicana and follows the Interstate to Ennis, where it branches off and continues through Waxahachie, crossing I-35E and continuing north through Tarrant County, where it encounters and briefly merges with three different Interstates (I-820, I-20, and I-35W). From Fort Worth, US287 continues north to Wichita Falls and continues just south of the Oklahoma border before entering the Texas Panhandle. A section of US287, between Midlothian and Waxahachie, was dedicated as the Chris Kyle Memorial Highway, in honor of fallen SEAL Chris Kyle, whose hometown was Midlothian.

The highway continues through Amarillo, where it intersects I-40, and then runs north to Kerrick and crosses into neighboring Oklahoma.

Oklahoma

In Oklahoma, US287 remains within Cimarron County, located at the end of the Panhandle. After crossing the state line north of Kerrick, Texas, the highway intersects SH 171 at its southern terminus. US287 continues northwesterly, crossing the Beaver River, toward Boise City, the county seat. On the east side of town, the highway formerly ran concurrently with US 56, US 64, US 412, and SH 3. These five highways then entered the traffic circle in downtown Boise City. US287 emerged from the north side of the circle, as well as US 385 and SH3. Now US 287 bypasses town to the east. These three highways (US 287, US 385, SH 3) head north to the Colorado state line. SH3 ends there, while US287 and US385 continue onward into Colorado.

Colorado

From Oklahoma, US287 and US385 enter into a very rural part of Colorado. They continue in a north/northwest direction through the state. The two highways pass through the town of Campo, and make an interchange with US160 on the outskirts of Springfield. In Lamar and Carlton, the highways make an interchange with US50. Here US385 heads east on US50, and US287/US50 continue to the north. Just outside the town the highways make a sharp turn toward the west, and the road heading north is SH 196. South of Wiley, US50 heads west, while US287 turns north toward Wiley. East of Eads, US287 turns toward the west again, briefly merging with SH 96. In Eads, SH96 continues toward the west, while US287 turns toward the north. Near Kit Carson, US287 again turns toward the west and merges with US40. Near Limon, the two highways make two interchanges with I-70 before passing through Limon. Then the two highways merge with I-70. Near the outskirts of Denver US36 merges with the group of highways making the road, I-70/US287/US36/US40.

Just past E-470, I-70 and US36 split to follow a more northerly course, while US287 and US40 continue west into Downtown Denver on Colfax Avenue. The I-25, US6, US87, and US85 interchange marks US287's second junction with its parent route, US87; the other is in Texas. Shortly thereafter, at a cloverleaf interchange with Federal Boulevard, SH 88 runs south, US40 continues west on Colfax, and US287 turns toward the north on Federal Boulevard. After crossing US36 (Denver–Boulder Turnpike), US287 turns west onto 120th Avenue where it overlaps SH 128. Just before meeting US36 again in Broomfield, US287 bends back to the north, leaving SH128 which continues west through an interchange with SH 121 and US36. At Baseline Road in Lafayette, SH 7 joins US287 for about a mile, before SH7 splits to the west on Arapahoe Avenue towards Boulder. It intersects SH 119 as it enters Longmont on Main Street, and then it intersects SH 66 at the north edge of town. In 2021 the Colorado State Senate Joint Resolution 21-018 designated the section of U.S. 287 between SH 66 in Longmont and SH 402 in Loveland as the SPC Gabriel David Conde Memorial highway. Gabriel Conde was a Berthoud High School graduate and a student at the Colorado School of Mines who joined the U.S. Army in 2015. He was killed in action in Afghanistan in April 2018. The road bypasses Berthoud en route to Loveland, where US287 splits into the pair of one-way streets Lincoln Avenue (northbound) and Cleveland Avenue (southbound). It then divides the Loveland cemetery. This is the only cemetery in the US with a US Highway dividing it. Continuing north, US287 passes through Fort Collins on College Avenue, merging with SH 14 at Jefferson Street. On the edge of the mountains at Ted's Place, SH14 splits and heads west into Poudre Canyon, while US287 continues north into Wyoming.

The section of US287 between Fort Collins and Laramie, Wyoming, carries very heavy truck traffic and is regarded as quite dangerous. A 2023 Colorado Department of Transportation report found the highway has above-average crash rates, making the highway a good candidate for more safety improvements. The 30-mile section from north of Fort Collins to the Wyoming line has had 570 crashes, including 15 fatal wrecks since 2019, and at least 15 students from the University of Wyoming in Laramie have died on the road since 2000.

Wyoming

US287 enters Wyoming through a pass between the Laramie Mountains to the east and the Medicine Bow Mountains to the west. In Laramie, US287 crosses I-80 and merges with US 30 and the two highways continue to head north. After passing Medicine Bow, these highways turn west-southwest and return to I-80 near Walcott, where they merge with the interstate west until Rawlins. US287 branches off from I-80 and US30 and heads into the town, following I-80 Business and US 30 Business for a short distance. In Downtown Rawlins, US287 leaves I-80 Business and US30 Business and merges with Wyoming Highway 789 (WYO789) to Lander, where WYO789 heads toward the northeast and US287 heads toward the northwest. US287 merges with US 26 in the very mountainous terrain of West Central Wyoming, and the two highways head west. The highways enter Grand Teton National Park. In Moran, US287 and US26 meet US 89 and US 191. US26 heads south merging with US191 and US89. US287 heads north merging with US191 and US89, passing through the John D. Rockefeller Jr. Memorial Parkway before ending at the South Entrance of Yellowstone National Park. While US287 and other U.S. Routes are officially discontinuous through the park, some commercially produced maps show these highways running inside Yellowstone National Park itself along its unnumbered roads and across the Wyoming–Montana state line.

Montana

US287 in Montana begins at the West Entrance of Yellowstone National Park in West Yellowstone, terminating a concurrency with US20. US287 and US191 split north of the town. US287 heads toward the northwest, merging with Montana Highway 2 (MT2) north of Sappington, and running northeast. At I-90, MT2 ends and US287 continues to head north. In Townsend, US287 merges with US12 and the two highways continue north. At I-15 (near Helena), US287 continues north on I-15 and US12 heads west through downtown Helena. Northeast of Wolf Creek, US287 and I-15 split with US287 heading northwest and I-15 heading northeast. US287 ends at US89 in Choteau.

History

When US287 was first commissioned in 1939, it extended only from the south entrance of Yellowstone National Park to Denver, Colorado. The route was extended southward to the Gulf Coast at Port Arthur, Texas in 1940, and northward into Montana to US 89 at Choteau, Montana in 1965. US89 continues north of Choteau into Alberta as Highway 2 through the major cities of Calgary and Edmonton, connecting with a Canadian link to the Alaska Highway in the latter.

Included in the route of US287 is former US 370, which was commissioned in 1926 and connected Amarillo to Bowie, traveling concurrently with US 70 between Vernon and Wichita Falls, Texas.

The Canada to Gulf Highway Association, which later became the U.S. Highway 287 Association, was active from the 1910s until the 1970s to promote US287 as a popular tourist route, and was composed of members from businesses and organizations in cities along the route.

The Wyoming state transportation department started widening US287 in 2009.

On April 22, 2021, the Oklahoma Legislature passed a bill that would rename part of US287 in Oklahoma after President Donald Trump; it went into effect on November 1, 2021.

Future

In 2017, House Bill 2026 (HB 2026) was filed in the Texas Legislature to provide funding for a study on upgrading US287 in Texas to an Interstate highway, with the eventual goal of designating US287 as an Interstate from Beaumont, Texas, to the Canadian border in Montana. HB 2026 later died in committee.

On May 11, 2026, U.S. Sen. John Cornyn (R-TX) introduced a bill to upgrade and rename US 287 as Interstate 47. Cornyn, who was seeking President Donald Trump's endorsement for re-election, said the conversion would save $5 billion in travel costs while honoring Trump, the 47th president.
