Placer/Nevada Counties - Caltrans is reminding motorists of various lane and ramp closures in multiple locations along Interstate 80 (I-80) as several construction projects are underway in Placer and Nevada counties.
Motorists will experience delays with each project. If traveling across the entire corridor, the cumulative delay may reach up to 2 hours depending on traffic volumes. Caltrans encourages motorists to factor in additional travel times along the I-80 Sierra corridor and check QuickMap for real-time roadway information.
Projects resuming for the 2026 season:
New projects for the 2026 season:
Additional work includes construction on a bridge deck preservation project at 14 various locations along Interstate 80 in Placer County and State Route 20 in Nevada County. Work includes a polyester concrete overlay, joint seal replacement and earthquake restrainer cable replacements. The project is expected to be completed by the end of the year.
Slope stabilization work is also underway along westbound I-80 between the Nevada/Sierra County line and Boca. This project is expected to be completed by this fall.
The extended lane closures will help to minimize the duration of the work and improve workers' safety. The schedule is subject to change or be delayed due to weather, availability of materials or other unexpected events.
Caltrans District 3 maintains 4,385 lane miles across 11 Sacramento Valley and Northern Sierra counties. Drivers are reminded to "Be Work Zone Alert" and slow in construction zones for safety.
The department issues construction updates on X @CaltransDist3 and Facebook CaltransDistrict3. For real-time traffic, click on Caltrans QuickMap or download the QuickMap app from the App Store or Google Play.
