Construction project on Third Street

The Transportation and Public Works Department builds and maintains the City’s vast infrastructure which includes streets, traffic signals, storm drains, bridges, sidewalks, street lights, and the City fleet which includes buses, fire engines, and police patrol cars.

A healthy infrastructure is critical to the economic vitality and quality of life in Santa Rosa, and it is crucial to public health and safety. We work to provide our community with a public infrastructure that functions smoothly and is environmentally sustainable.
