Nevada County - Caltrans is alerting motorists of various ramp and shoulder closures along State Route 20/49 (SR-20/49) in Nevada County as part of the $26 million Gold Nugget Project.

Motorists can expect various ramp closures between Grass Valley and Nevada City starting Sunday, March 31 from 6 p.m. to 6 a.m. Construction activity will pause Friday morning and resume the following Sunday night, continuing throughout the end of April.

Crews are working to upgrade these facilities to current Americans with Disabilities Act (ADA) standards. Roadside message signs will be in place along SR-20/49 to alert motorists of the closures and will not affect multiple ramps in succession.

Additionally, various shoulder closures will take place during the day for electrical and clearing work, but they are expected to have little impact to the traveling public.

The schedule is subject to change or be delayed due to weather conditions, material availability, or other unexpected events.

The work kicks off the beginning of the Gold Nugget Project, which will rehabilitate the pavement between the SR-20/49 separation and Stonehill Road/Dow Road. The project will replace sign panels, upgrade Transportation Management System elements, and rehabilitate drainage systems within the area.

DeSilva Gates Construction LLC of Dublin is the prime contractor for the project, which is expected to be completed by winter 2025.

Caltrans District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties. Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements. 

The department will issue construction updates on @CaltransDist3 and on Facebook at CaltransDistrict3. For real-time traffic, click on Caltrans’ QuickMap or download the QuickMap app from the App Store or Google Play.
