Route description

SH-4 begins at an intersection with I-90 in Wallace, then heads generally northeast through Burke Canyon, past historical markers for Frisco Hill and Burke, ending in Burke. The road continues eastward as National Forest Road No. 7623.^[1][2]

History

In the 1930s, Route 4 was envisioned as a cross-state route, to directly connect Wallace to Thompson Falls, Montana over Glidden Pass, as seen on the 1937 map (later routed over Cooper Pass).^[3] This plan was abandoned due to impassable roads and World War II. Paved SH-4 was truncated at Burke.

National Forest Road 7623 still connects Burke to Montana Secondary Highway 471 leading to Thompson Falls.

Major intersections

The entire route is in Shoshone County.
