State Route 1 Bridge Rail Replacement Project

Project overview

Caltrans is in the design phase of the Bridge Rail Replacement project on State Route 1 in Marin County.

Caltrans is proposing to remove and upgrade the existing bridge rails at Coyote Creek Bridge, Eskoot Creek Bridge, Olema Creek Bridge South and Olema Creek Bridge North. The target for construction is summer of 2028.

The purpose of the project is to address bridge railing systems on the four bridge structures on SR-1. The project is needed to meet current Caltrans’ bridge railing safety standards. Safety standards for roadway design consider speed, transportation modes, surrounding land use, size of current vehicles using the road, and the required safe distances between motorized and non-motorized traffic. The four bridges range from 65 to 95 years old.

There are no full closures scheduled for this project. One-way traffic control with temporary signals will be utilized during construction activities for work on the Eskoot and Olema bridges.

The project would also include widening the bridge locations on each side for a total of approximately 16 inches to accommodate the upgraded bridge railings.

The project would be funded by the State Highway Operation and Protection Program (SHOPP). SHOPP is California’s “fix-it-first” program, which funds the repair and protection of the State Highway System, safety improvements, and some highway operational improvements.

Project Schedule

The target for the start of construction is summer of 2028.

The target for the completion of construction is fall 2029.
