Progress Continues on the SR-1 Multi-Asset Roadway Rehabilitation Project

Crews conducting paving south of Half Moon Bay Airport

San Mateo County ― Caltrans is continuing electrical and paving work on the State Route 1 (SR-1) Multi-Asset Roadway Rehabilitation Project between Moss Beach and Half Moon Bay. Paving work is nearly complete near Half Moon Bay Airport and will continue between Coronado Street and Ruisseau Francais Avenue through June 5. A base layer of pavement will be laid on the roadway initially, and final paving work is expected to be completed by the end of August 2026.

Since most work takes place overnight, drivers should expect that lane closures and one-way traffic control will result in minor delays between 9 p.m. and 7 a.m.

Below are some views of the progress along the project corridor.

 

Please note

• Unscheduled closures: On rare occasions, lanes may be closed as early as 6 p.m., and some daytime lane closures may be necessary at short notice. Work schedules may change due to weather.
• Temporary striping: The striping is temporary and the paint may show slight smudging. Final striping will be performed at the end of the project.
• Signals & crosswalks: Signal operations will be set to an optimized schedule during construction at many intersections instead of "on-demand" activation. Drivers may notice delays even when pedestrians or cross traffic are not present. The sensors will be reactivated once the electrical work has been completed at each intersection.

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.
