The California Department of Transportation (Caltrans) is alerting motorists about upcoming nightly closures of westbound I-80 between Secret Town Road and the junction with State Route 174 (SR-174) as emergency pavement repairs continue near Colfax.

The nightly closures  are scheduled from 8:00 p.m. to 6:00 a.m. Monday, October 16 through Thursday, October 19. Westbound I-80 is scheduled to fully reopen by 6:00 a.m. Friday, October 20.

Two separate detours will be in place with changeable message signs in place to alert motorists of the alternate routes.

  • Passenger vehicles will be detoured west on Rollins Lake Road to SR-174 and reconnect with I-80 in Colfax. 
  • Large trucks, RVs and buses will be detoured west on State Route 20 to Nevada City, then head south on State Route 49 to Bell Road and reconnect with I-80 in Auburn. The truck detour will start at 7:00 p.m., one hour prior to the closing of I-80.

The extended lane closures will help to minimize the duration of the project, speed completion and improve workers’ safety. The climate in the area also provides a limited temperature window to perform the needed repairs.

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.
