The Orange County Transportation Authority (OCTA), in coordination with Metrolink, is replacing the railroad bridge over San Juan Creek. Built in 1917, the bridge has reached the end of its useful life and will be replaced by a new three-span girder bridge.
The San Juan Creek Bridge Replacement Project is replacing the railroad bridge over San Juan Creek in the City of San Juan Capistrano.
The project is constructing a new three-span girder bridge west of the existing bridge. The new bridge will enhance safety, reduce maintenance needs, and meet current design and bridge load standards. The existing bridge will be demolished, and a new foundation and substructure will be installed for a potential future bridge. There are no plans to construct a second bridge but if a need arises, the supporting infrastructure will be in place.
The bridge serves Metrolink and Amtrak Pacific Surfliner passenger trains, as well as freight trains.
Crews have removed the main structure of the old railroad bridge and have begun the demolition of the concrete substructure, or foundation. This work is expected to continue through April.
Beginning in late April, crews will transition to construction of a new foundation for a potential future bridge. Activities will include drilling, pile installation, and concrete pours. In preparation for this work, material deliveries are expected to occur for approximately two weeks. Trucks will enter the work area through Camino Capistrano and exit through Stonehill Drive.
Work is expected to occur during daytime hours, between 6 a.m. and 6 p.m., Monday through Saturday.
This work may be loud. The schedule is subject to change due to inclement weather or unforeseen operational issues.
