White Bridge Road provides vehicle access across the Boulder River via a two-lane bridge (built 1979) located 6 miles southeast of Boulder, serving as a key trailhead gateway to the Elkhorn area recreation zone.

The bridge carries light traffic (approximately 100 vehicles daily) and provides access to multiple hiking and riding trails including routes to Elkhorn and Crow Peaks, Leslie Lake, and Glenwood Lake.

This is the primary access point for reaching the Elkhorn Road trail system and surrounding Forest Service lands in the Boulder Mountains.
