Highway system

U.S. Route 287 (US 287) is a north–south (physically northwest–southeast) United States highway. At 1,791 miles (2,882 km) long,[citation needed] it is the second longest three-digit U.S. Route, behind US 281. It serves as the major truck route between Dallas-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 unnumbered park roads serve as a connector.

The highway's northern terminus is in Choteau, Montana, 100 miles (160 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 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 is the shortest route between Denver and Dallas-Fort Worth.
