San Mateo County ― Caltrans continues work on the State Route (SR) 1 Multi-Asset Roadway Rehabilitation Project with concrete, electrical, and paving work. There will be overnight lane closures at various locations between Marine Blvd. in Moss Beach and Wavecrest Road in Half Moon Bay, most occurring between 8 p.m. and 6 a.m., starting on Wednesday, March 18. All work will take place on weeknights.

  • Crews will close lanes to accommodate overnight electrical work at the intersections of SR-1 & SR-92 and SR-1 & Main Street in Half Moon Bay starting on Wednesday, March 18 and lasting approximately two weeks.
  • Excavation work will start Monday night, March 23, and continue nightly for approximately two weeks, Monday through Friday nights. People who live close to the work sites will be notified in advance and should expect some nighttime noise. Excavation work will create enough room for a new bike lane and buffered striping area to enhance bicyclist safety. Work will take place at each location for two to three nights:
    • Between Poplar St. and Kelly Ave.
    • South of Mirada Rd.
    • North and South of Magellan Ave.
    • Between Coronado and Capistrano Rd.
    • Near Coral Reef Ave.
    • Near North Capistrano Rd.
  • Concrete and electrical work will take place nightly at the intersection of SR-1 and Kelly Avenue during the week of April 13-17.
  • In early April, roadway paving work will begin, necessitating lane closures at various locations within the project limits.

Please expect minor delays and allow extra time. Some daytime work may be necessary at short notice.

Known as the SR-1 Multi-Asset Roadway Rehabilitation Project, the $46.7M project encompasses upgrading assets (such as pavement, guardrails, curbs, and crosswalks) that are nearing the end their service lives. Assets will be brought up to ADA standards, and Class II bike lanes will be added to both the north- and south-bound sides of the roadway. The project will continue through the summer of 2027. To learn more, visit the project website.

This work is funded by the State Highway Operation and Protection Program (SHOPP). SHOPP is the State Highway System's “fix-it-first” program that funds the repair and preservation on the state's highway system.

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.
