U.S. Route 87 (US 87) is a part of the U.S. Highway System that travels Port Lavaca, Texas, north to Havre, Montana. In the state of Montana, It extends approximately 444 miles (715 km) from the Wyoming state line near Wyola north to its terminus at US 2 near Havre.
Route description
US 87 enters Montana running concurrently with Interstate 90 (I-90) and travels westward for 45.3 miles (72.9 km) to Crow Agency, where US 212 merges with the route. The three routes continue westward for another 54.6 miles (87.9 km) to Billings, where it intersects with the western terminus of I-94 in suburban Lockwood. US 87 follows the I-90/US 212 concurrency for another 3.3 miles (5.3 km) before it heads north, following Main Street through Billings Heights. US 87 continues north for 51 miles (82 km) and intersects US 12, sharing a 2.1-mile (3.4 km) concurrency through Roundup. US 87 continues north with a slight bend to the northwest for 44.7 miles (71.9 km) until it intersects Montana State Highway 200 (MT 200) near Grass Range and takes a sharp turn west; US 87 remains concurrent with MT 200 until Great Falls. US 87 and MT 200 travel west for 30.6 miles (49.2 km) to Lewistown, where they merge with US 191 and continue heading generally westward. About 14.3 miles (23.0 km) west of Lewistown near Moore, it breaks with US 191 and merges with MT 3, where they head northwest for 64.7 miles (104.1 km) and merge with US 89 near Armington. The four-route concurrency of US 87/US 89/MT 3/MT 200 continues northwest for 22.7 miles (36.5 km) to Great Falls, where US 87 leaves all three and travels north through the city. North of Great Falls, US 87 travels northeast for 37.4 miles (60.2 km) to Fort Benton and a final 70 miles (110 km) to its terminus with US 2, about two miles (3.2 km) west of Havre.[1]
History
US 87 originally ran northwest out of Great Falls towards the eastern border of Glacier National Park to the Canadian Border at the Piegan Border Crossing. This was changed in 1934, when US 89 was diverted to US 87's routing north of Great Falls. US 87 terminated in Great Falls until c. 1945 when it was extended to its current northern terminus near Havre.[2]
