San Mateo County ― Caltrans has implemented an overnight detour from westbound SR-92 to southbound U.S. 101 while crews construct bridge column foundations. The detour will remain in effect nightly through the end of October 2025, from 9 p.m. to 5 a.m.

Detour route:

  • Exit SR-92 at Concar Dr.
  • Turn right onto Concar Dr.
  • Turn right onto South Delaware St.
  • Follow signs to eastbound SR-92, then connect to southbound U.S. 101.

This work is part of the $45M U.S. 101- SR-92 Short-term Improvements Project that is co-sponsored by the San Mateo County Transportation Authority and City/County Association of Governments. The project will bring operational improvements, enhancement to local access, and promotion of economic vitality to the region.

All work is weather dependent. Please drive with caution. Thank you for your patience as we work to maintain our state’s highways, bridges, and tunnels.
