Arroyo de la Laguna Bridge Project
NOP - Notice of Preperation
Caltrans proposes to replace the existing bridge over Arroyo de la Laguna with a new bridge structure. Recent structure maintenance inspections (completed in Oct of 2013) identified that drift at Piers 4 and 5 of the Arroyo de la Laguna Bridge is causing scour, which will potentially undermine the footing at Pier 5 of this bridge site. Furthermore, the existing 1939 railing of the Arroyo de la Laguna Bridge does not meet current safety standards and needs to be updated to meet current standards. Modern bridge railing is better able to redirect errant vehicles back into the existing roadway. The purpose of the project is to mitigate bridge scour, protect the bridge's structural integrity and improve safety by directing potentially errant vehicles back into the roadway.
