  • We are currently replacing the one-lane bridge over the South Fork of the Gualala River with a two lane, 29 foot wide and 165 foot long steel bridge. The new bridge will be constructed adjacent to the existing bridge, and will provide two lanes designed to meet current standards, including shoulders and improvements to the approaching roadway. The existing bridge will remain in place through the construction process.

  • The project is located on Highway 101 at Airport Boulevard in Sonoma County between the cities of Santa Rosa and Windsor near the Sonoma County Airport. The project proposes to construct landscape improvements through an encroachment permit issued by Caltrans as a follow up to the Highway 101 North/Airport Boulevard interchange and sound walls project.
  • We will be constructing ADA related improvements at various locations along Bohemian Highway and throughout Occidental beginning later this summer and continuing over the winter into spring 2018. The project will bring sidewalks, curb ramps, parking stalls, crosswalks and other paved areas into compliance with ADA standards and provide safer access for all users on both sides of Bohemian Highway within the commercial downtown area.
