Castillo Street Undercrossing Bicycle and Pedestrian Facility Improvements

The City received a Measure A grant to develop a concept design for bicycle and pedestrian facility improvements at the approaches of the Castillo Street undercrossing at U.S. Highway 101. 

As part of the community engagement process of the Planning Effort in 2022, residents requested the City to investigate elevating the bike lanes to sidewalk level within the undercrossing to get cyclists out of the roadway, which is consistently wet due to a high-water table. The City has coordinated with Caltrans to propose multiuse paths in the undercrossing as part of the project. 

Proposed improvements on Castillo and Haley Streets include multiuse paths, separated bike paths, street trees to provide sidewalk separation, new lighting facilities, sidewalk widening and repair, and changing the 400 block of Bath Street to a one-way street. 

The City applied for grant funding in June of 2024 through the State’s Active Transportation Program (Program) Cycle 7 to design and construct bicycle and pedestrian safety enhancements along Castillo and Haley Streets, refined through the Planning Effort. Although the application scored well, it was unsuccessful. The City will continue to seek grant funding opportunities for the implementation of this important safety project.
