Ongoing lane closures on SR-1 between Moss Beach and Half Moon Bay for electrical and curb work continue through March

San Mateo County ― Caltrans is continuing to perform electrical and barrier placement work between Moss Beach and Half Moon Bay. Various right-hand lanes, turn pockets, and shoulders near intersections will have temporary barriers. Traffic control personnel will be onsite to guide traffic and pedestrians through any affected areas. This phase of the project work is expected to be completed in mid-March.

Residents may hear noise overnight at the end of January or early February while heavy, temporary concrete barriers are placed on the roadway which will protect pedestrians and construction crews during construction.

We will ensure access for pedestrians and cyclists during this phase of the project. Curb ramps will meet Americans with Disabilities Act (ADA) standards, ensuring safe access while work is underway.

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.

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.
