Donner Pass Road Construction

This project consists of road rehabilitation and shoulder widening on 6.5 miles of Donner Pass Road beginning at the Soda Springs exit and ending at the Truckee town limit east of the summit. Nevada County received California Federal Lands Access Program (FLAP) funding for this project in 2015. The project is being managed by the Central Federal Lands Highway Division (CFLHD). The project will:
- Improve recreational and sightseeing access.
- Enhance parking on the east side of the summit for rock climbing, hiking, and biking.
- Create bike lanes in both directions on the west side and in the uphill direction on the east side.
