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 scheduled to perform nighttime utility work as soon as Monday, June 9, from 9 p.m. to 5:30 a.m. for approximately four weeks. Noise and lighting from the operation are expected.
Crews are in the final stages of installing steel beams, work that began in early May, which required drilling 100-foot-long sheet piles along the slope embankment within San Juan Creek. This activity uses vibratory and diesel hammers where the adjacent community may continue to experience noise and vibration. This work is expected to continue through Saturday, June 7.
This work may be loud. Schedule is subject to change due to inclement weather or unforeseen operational issues.

The San Juan Creek Trail is expected to be closed as soon as Monday, June 16 for approximately one week. The closures are Monday through Friday, from 6 a.m. to 5 p.m., and would allow crews to continue construction activities safely around the bikeway underpass. The bike path will reopen at the end of each work day.
Trail users will be detoured to Camino Capistrano, Del Obispo Street and the Trabuco Creek Trail.
Another closure of the trail is anticipated this summer. More information will be available in future communications.
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.
