San Juan Creek Bridge Replacement Project

under construction

The project involves the construction of a new three-span girder railroad bridge adjacent to the century-old bridge it replaces. The new bridge serves Metrolink and Amtrak Pacific Surfliner passenger trains, as well as freight trains. It is designed to enhance safety, reduce maintenance needs, and meet modern bridge load standards. Additional works include new tracks, retaining walls, utilities, signals, and a bikeway underpass to improve safety and connectivity. The old bridge will be dismantled and a new foundation and substructure will be installed to accommodate a possible future second bridge, though no immediate plans exist for expansion.
