Caltrans, in partnership with the Mendocino Council of Governments, proposes an enhancement project on State Route 1 through downtown Gualala (post miles 0.6 to 1.0). The current design of the downtown area of Gualala has several deficiencies that could increase conflicts between motorized users, cyclists, and pedestrians.

Caltrans proposes to replace the Salmon Creek Bridge on Route 1. The current bridge, built in 1950, has a concrete deck over steel beams. The bridge is functionally obsolete because it is narrow and does not meet current standards for shoulders and guardrails.

The purpose of the project is to remediate lead-impacted shallow soil in the State Right-of-Way and on the privately-owned parcels adjacent to the Salmon Creek Bridge. The project is needed because historic bridge painting practices resulted in elevated lead concentrations in shallow soils beneath and east of the Salmon Creek Bridge.
