Albion River Bridge Rehabilitation/Replacement
This project will evaluate rehabilitating or replacing the Albion River Bridge on Route 1 in Mendocino County near the town of Albion.
This project is needed because the bridge is narrow, it does not meet current standards for shoulders and guardrails, and maintenance costs are high.
Caltrans has updated the Transportation Concept Report (TCR) for Route 1. TCRs are planning documents that describe the Department's conceptual improvement options for a given transportation route or corridor.
Caltrans and their consultants have conducted two investigations at the bridge site. The first, completed in June 2014, termed a "bridge Survey," determined the concentration of wood preservative constituents in the structural members of the bridge for waste classification, the level of lead present in the bridge rail paint system, and if asbestos containing materials were present. This "survey" investigation provided a group of "constituents of concern" (COCs) used to direct the follow up investigation. The second investigation, termed a "preliminary Site Investigation" (PSI), completed in December 2014, focused on determining if a release of any COCs had occurred in the immediate vicinity of the bridge. All investigations to date have occurred within the 100-foot wide State Highway Right of Way at the bridge site.
