One segment of the historic Bridger Trail was recorded in Hot Springs County. The segment is located along the top and slope of an unnamed ridge near the top of the Bridger Mountain Range northwest of the town of Lysite and southeast of Thermopolis.

This segment was evaluated for its National Register of Historic Places eligibility. This is a measure of how important and unique the site is. The Bridger Trail as a whole is eligible for listing on the National Register because of its significance as an interregional transportation route through Wyoming to the gold fields of Montana and because of its association with mountain man and guide Jim Bridger. This segment in particular was recommended as contributing to the site's overall National Register eligibility. The segment in this area retains good overall physical integrity characterized by a gentle swale and lightly used two-track road. The surrounding viewshed also possesses excellent integrity of location, setting, feeling, and association due to the lack of man-made intrusions on the landscape.

The recording and evaluation was done to mitigate effects to the trail from construction of the Express Pipeline in Wyoming. Cultural resource mitigation for the site also included large-scale photographic documentation of the segment, a published monograph on the Bridger Trail, and placement of an interpretive sign along the east side of Wyoming State Highway 16/20 north of Lucerne, Wyoming.
