Highway 287 (MT 287) is a state highway in the U.S. state of Montana. The highway runs 42.822 miles (68.915 km) from MT 41 in Twin Bridges east to U.S. Route 287 (US 287) in Ennis. MT 287 is the primary east–west highway of Madison County. The highway connects the county's four towns, including Sheridan and the county seat of Virginia City. The course of MT 287 follows the ultimate portions of two trails that met in Virginia City, the center of the Alder Gulch gold rush of the mid-1860s and the second territorial capital of Montana. Parts of the highway were improved from rudimentary roads around 1920 from Virginia City to Ennis. This connection became the first portion of Montana Highway 34 in the early 1930s; the highway was extended west to Twin Bridges in the late 1930s. MT 34 was reconstructed from Twin Bridges through Alder to Virginia City in the late 1930s and early 1940s and between Virginia City and Ennis in the late 1940s to mid-1950s. The MT 287 designation was first applied to a cross-state route from West Yellowstone to Canada in the late 1950s. The highway was rerouted to assume MT 34 in the early 1960s and was removed from the cross-state corridor, along which it was mostly replaced by US 287, in the mid-1960s. MT 287 extended north of Twin Bridges to Whitehall until the late 1970s, when it achieved its current length.
