U.S. Route 287 (US 287) is a north–south (physically northwest–southeast) United States highway. It is 1,791 miles (2,882 km) long.[ citation needed] It serves as the major truck route between Fort Worth and Amarillo, Texas, and between Fort Collins, Colorado, and Laramie, Wyoming. The highway is broken into two segments by Yellowstone National Park, where an unnumbered park road serves as a connector.
The highway's northern terminus is in Choteau, Montana, 100 miles (160.9 km) 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 (SH 87), five miles (8.0 km) 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.
US 287 originates at its southern terminus in Port Arthur as a branch of SH 87. From Port Arthur, US 287 runs concurrently with US 69 and US 96 to Lumberton, where US 96 diverges to the northeast and the co-signed US 287/US 69 continues northwesterly until US 287 and US 69 diverge in Woodville. Continuing northwesterly, US 287 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, US 287 continues north to Wichita Falls and continues just south of the Oklahoma border before entering the Texas Panhandle. A section of US 287, between Midlothian and Waxahachie, was dedicated as the Chris Kyle Memorial Highway, in honor of fallen SEAL Chris Kyle, whose hometown was Midlothian.
In Oklahoma, US 287 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. US 287 continues northwesterly, crossing the Beaver River, toward Boise City, the county seat. On the east side of town, the highway runs concurrently with US 56, US 64, US 412, and SH 3. These five highways then enter the traffic circle in downtown Boise City. US 287 emerges from the north side of the circle, as well as US 385 and SH 3. These three highways head north to the Colorado state line. SH 3 ends there, while US 287 and US 385 continue onward into Colorado.
From Oklahoma, US 287 and US 385 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 US 160 on the outskirts of Springfield. In Lamar and Carlton, the highways make an interchange with US 50. Here US 385 heads east on US 50, and US 287/US 50 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, US 50 heads west, while US 287 turns north toward Wiley. East of Eads, US 287 turns toward the west again, briefly merging with SH 96. In Eads, SH 96 continues toward the west, while US 287 turns toward the north. Near Kit Carson, US 287 again turns toward the west and merges with US 40. 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 US 36 merges with the group of highways making the road, I-70/US 287/US 36/US 40.
Just past E-470, I-70 and US 36 split to follow a more northerly course, while US 287 and US 40 continue west into Downtown Denver on Colfax Avenue. The I-25, US 6, US 87, and US 85 interchange marks US 287's second junction with its parent route, US 87; the other is in Texas. Shortly thereafter, at a cloverleaf interchange with Federal Boulevard, SH 88 runs south, US 40 continues west on Colfax, and US 287 turns toward the north on Federal Boulevard. After crossing US 36 (Denver–Boulder Turnpike), US 287 turns west onto 120th Avenue where it overlaps SH 128. Just before meeting US 36 again in Broomfield, US 287 bends back to the north, leaving SH 128 which continues west through an interchange with SH 121 and US 36. At Baseline Road in Lafayette, SH 7 joins US 287 for about a mile, before SH 7 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. The road bypasses Berthoud en route to Loveland, where US 287 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.[ citation needed] Continuing north, US 287 passes through Fort Collins on College Avenue, merging with SH 14 at Jefferson Street. On the edge of the mountains at Ted's Place, SH 14 splits and heads west into Poudre Canyon, while US 287 continues north into Wyoming. The section of US 287 between Fort Collins and Laramie, Wyoming, carries very heavy truck traffic and is regarded as quite dangerous. 
US 287 enters Wyoming through a pass between the Laramie Mountains to the east and the Medicine Bow Mountains to the west. In Laramie, US 287 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. US 287 branches off from I-80 and US 30 and heads into the town. US 287 merges with Wyoming Highway 76 (WYO 76), WYO 82, and WYO 30 for a short distance just outside Rawlins, though WYO 76 ends when US 287 branches to the northwest as a stand-alone highway. It is also possible to take Business US 287 (WYO 80, WYO 30) into Rawlins. In Downtown Rawlins, WYO 80 and WYO 30 head toward the west while Business US 287 heads to the north, merging with WYO 789 where WYO 30 and WYO 80 split off the highway. A short while later Business US 287 and WYO 789 merge with mainline US 287, which made a detour around the city. US 287 and WYO 789 stay merged all the way to Lander, where WYO 789 heads toward the northeast and US 287 heads toward the northwest. US 287 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, US 287 and US 26 meet US 191 and US 89. US 26 heads south merging with US 191 and US 89. US 287 heads north merging with US 191 and US 89, and as it reaches Yellowstone National Park, becomes an unsigned park road and continues into Montana.
US 287 in Montana begins at the West Entrance of Yellowstone National Park in West Yellowstone, terminating a concurrency with US 20. US 287 and US 191 split north of the town. US 287 heads toward the northwest, merging with Montana Highway 2 (MT 2) north of Sappington, and running northeast. At I-90, MT 2 ends and US 287 continues to head north. In Townsend, US 287 merges with US 12 and the two highways continue north. At I-15 (near Helena), US 287 continues north on I-15 and US 12 heads west through downtown Helena. Northeast of Wolf Creek, US 287 and I-15 split with US 287 heading northwest and I-15 heading northeast. US 287 ends at US 89 in Choteau.

When US 287 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. US 89 continues north of Choteau into Alberta as Provincial Highway 2 through the major cities of Calgary and Edmonton, connecting with a Canadian link to the Alaska Highway in the latter.
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 US 287 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 US 287 in 2009. 
According to an article in the Fort Worth Star Telegram, plans are being discussed for US 287 to be designated as an interstate highway running from Beaumont, Texas to the Canadian border in Montana.
