Manuel T. Freitas Roundabout in San Rafael Completed

Caltrans opened the Manuel T. Freitas Roundabout as well as the intersection of Civic Center Drive and Redwood Highway on the morning of Monday, June 8.

The intersection had been closed since February to necessitate the construction of the roundabout, a new bus stop and northbound slip on-ramp.
This project is expected to improve the intersection of Freitas Parkway, Civic Center Drive, and Old Redwood Highway. This change is expected to improve traffic flow and make this busy intersection/off-ramp safer for vehicles and pedestrians.

Caltrans relocated the bus stop at the northbound Freitas Parkway off-ramp to make it safer and Americans with Disabilities Act (ADA) accessible.
The project was coordinated with Marin Transit and the City of San Rafael for bus stop relocation/improvements in the City’s Right of Way.

Lagunitas Creek Bridge Replacement Project Starts One-Way Traffic Control in Summer 2026

Caltrans started one-way traffic control for the much-anticipated Lagunitas Creek Bridge Replacement Project in West Marin on Monday, Aug. 10. Work this summer and fall includes widening the overflow culvert and installing foundations for the new bridge within the roadway.

The project will require a 21-day full bridge closure scheduled to occur after Labor Day weekend in 2027. During the full closure, a detour will be implemented to safely redirect traffic around the bridge.

This project will replace the Lagunitas Creek Bridge. In addition, the culvert north of the bridge will be widened to match the new bridge width. The new bridge will have wider shoulders and will provide sidewalk and curb ramps that will be ADA-compliant. A crosswalk will also be added across Sir Francis Drake Boulevard at the SR-1 intersection to provide continuous safe access over Lagunitas Creek and into Point Reyes Station.

The Lagunitas Creek Bridge is located just south of Point Reyes Station and north of the intersection with Sir Francis Drake Boulevard, approximately four-tenths of a mile east of the San Andreas fault. The bridge, which was built in 1929, is a three-span structure with a total length of 152 feet.

Capital Preventive Maintenance Project on State Route 131 (Tiburon Boulevard) Scheduled to Start Soon

Caltrans is in the construction phase of the Capital Preventive Maintenance Project on State Route 131 (Tiburon Boulevard).

Construction on curb ramps and sidewalks is scheduled to begin as early as Aug. 31. One-way traffic control may be used at some intersections between the hours of 7 a.m. and 5 p.m. Monday through Friday. Paving for the project is scheduled for spring 2027 between the hours of 11 p.m. and 6 a.m.

The purpose of this project is to improve serviceability and ride quality on SR-131 and restore existing drainage systems to reduce the potential for highway flooding and to increase the safety for the public.

In addition, the project will enhance and complete streets and support active modes of transportation by bridging a gap in the transportation network and improve bicycle access throughout the area.

The location is approximately 1,000 feet west of US-101 interchange to the Tiburon Boulevard/Main Street intersection.
