SR 1 Capital Preventive Maintenance

Caltrans District 4 (Bay Area) is about 99 percent finished with the State Route 1 (SR-1) Capital Preventive Maintenance Project in West Marin as of November 2025.

The project helped rehabilitate 27.8 lane miles overall - including 13.9 miles of SR-1. The project also improved drainage (eight culvert replacements) and upgraded Americans with Disabilities Act (ADA) facilities.

The project included upgrades to existing SR-1 infrastructure, including pavement rehabilitation, curb ramp upgrades in the communities of Point Reyes Station and Tomales, replacement of guardrails and crash cushions, upgrading of drainage inlets, and replacement of aging culverts.

The project also includes improvements to crosswalks and signage in Point Reyes Station and improvements to sidewalks in the town of Tomales.

To improve safety, flashing beacons were added in Point Reyes Station and Tomales along with a hybrid beacon in Tomales and a pair of radar speed feedback signs in Tomales.

Many of the safety improvements included sidewalk and path upgrades to meet disability access standards and improve access to West Marin-Inverness School in Point Reyes Station.

Caltrans coordinated with the Safe Routes to School Committee in 2018 and 2019. Additionally, Caltrans has performed public outreach meetings in April of 2019 and March of 2021. The agency has local partnerships with the County of Marin and the Transportation Authority of Marin (TAM) for additional improvements on the Mesa Road intersection.

There are some remaining items that still need to be finished with the project, including the plant establishment period. The target date for that to be finished is summer 2026.
