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 will replace the railroad bridge over San Juan Creek in the City of San Juan Capistrano.
The project will construct 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 are expected to trim trees within rail right of way to ensure the rail line remains safe and operational. This daytime work is anticipated to begin on Tuesday, Aug. 19 and is expected to take approximately one week.
Nighttime utility work is now expected to continue into September as crews continue to perform underground utility work related to the relocation of communication and signal lines.
The adjacent communities may experience noise and lighting from the operation. Train horns may also sound because the Federal Railroad Administration (FRA) guidelines require that all trains sound their horns when workers are present on or around railroad tracks. This federal mandate applies to construction zones.
This work may be loud. This schedule is subject to change due to inclement weather or unforeseen operational issues.
Federal Railroad Administration (FRA) guidelines require all trains to sound their horns when workers are present, in emergency situations or when there are trespassers on or around railroad tracks. This federal mandate applies to construction zones. As a result, for the safety of construction workers, train crews and passengers, and the public, horns will be sounded when trains pass through the area.
The public and businesses adjacent to the work area may experience noise and vibration from demolition and drilling activities as well as light from construction operations. Noise may also be generated from construction equipment back-up alarm. The alarms are required by state regulation.
The Public Outreach team regularly hosts project information booths at Descanso Park in San Juan Capistrano. In addition, the team participates in community events.
