This road was intended to be a safe and acceptable alternate to the Bozeman Trail, connecting the Oregon Trail at Fort Caspar with the gold fields in western Montana via a route west of the Big Horn Mountains.
Mountainman Jim Bridger established the route under contract with the Army Corps of Engineers. The trail did see some emigrant and freight wagon use, but became more important later as Wyoming settlers started to move into the Big Horn Basin.
The Bridger Trail is not marked and is still not well known. Much of the Trail west of Casper crosses BLM administered public lands. Once in the Big Horn Basin, most of the Trail is on private land.
