U.S. Highway 87 (US 87) is a north–south United States highway (though it is signed east–west in New Mexico) that runs for 2,005 miles (3,227 km) from northern Montana to southern Texas, making it the longest north–south road to not have a "1" in its number and the third longest north–south road in the country, behind U.S. 41 and U.S. 1. Most of the portion from Billings, Montana to Raton, New Mexico is co-signed along Interstates 90 and 25. It is also co-signed along the majority of I-27 in Texas and future plans call for the interstate to be extended along the US 87 corridor. As of 2004, the highway's northern terminus is in Havre, Montana, at US 2 and its southern terminus is in Port Lavaca, Texas, at SH 238.
