Caltrans Holds Second Informational Session for Lagunitas Creek Bridge Replacement Project on Oct. 9 in Point Reyes

About 35 members of the public attended the second informational session on Wednesday, Oct. 9, 2024 at The Dance Palace in Point Reyes.

Caltrans provided information to the public about the Lagunitas Creek Bridge Replacement Project, which is scheduled for construction on State Route 1 (SR-1) in the summer of 2026.

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. It serves as a vital connection between communities north and south of Point Reyes Station for residents, tourists, delivery trucks, emergency responders, transit providers, pedestrians, bicyclists, and equestrians.

Caltrans has completed final designs for the project, which will replace the Lagunitas Creek Bridge with a new bridge including wider shoulders and an Americans with Disabilities Act (ADA)-compliant sidewalk and curb ramps.

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. In addition, the culvert north of the bridge will be lengthened to match the new bridge width.

This project plans to maintain a long-term local and regional connectivity for the surrounding communities in Marin County. This project also will be presented at an upcoming California Coastal Commission hearing.


Overview

Caltrans District 4 (Bay Area) is in the design phase of the Lagunitas Creek Bridge Replacement Project on State Route 1 (SR-1) near Point Reyes Station.

Caltrans determined that the Lagunitas Creek Bridge (also known as the Green Bridge) does not meet safety and seismic design standards.

The project proposes to 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.

This project plans to provide a long-term, sustainable solution, maintaining long-term local and regional connectivity for the surrounding communities in Marin County. 

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. It serves as a vital connection between communities north and south of Point Reyes Station for residents, tourists, delivery trucks, emergency responders, transit providers, pedestrians, bicyclists, and equestrians. The bridge, which was built in 1929, is a three-span structure with a total length of 152 feet.

Caltrans performed confirmatory drilling for the project in March 2024. One-way traffic control was utilized. No other drilling is scheduled in 2024.

Projected start of construction: Summer of 2026
Projected time for completion: Summer of 2028
