San Juan Creek Bridge Replacement Project

Construction Updates

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.

Project Details

SJC 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.

The project will also:

  •    Construct tracks
  •    Construct a new bikeway underpass
  •    Construct retaining walls
  •    Install new utilities and signals
  •    Remove vegetation

Eastbound Del Obispo Lane Closure the Week of Oct. 6

Crews are currently hauling away track materials through the Del Obispo crossing. Several large trucks are entering via the Del Obispo crossing and exiting at Stonehill Drive. To complete this work safely, the outside lane of eastbound Del Obispo Street, between Paseo Adelanto and Camino Capistrano, will be closed nightly from 9 p.m. to 5 a.m. for approximately one week. Westbound Del Obispo remains open.

This work may be loud. This schedule is subject to change due to change of weather or unforeseen operational issues.

Construction Progress

OCTA, in coordination with Metrolink, is replacing a 108-year-old railroad bridge over San Juan Creek with a new three-span girder bridge that is being constructed west of the existing bridge, built in 1917.

A passenger service outage in late September allowed crews to efficiently perform track-related activities, including removing rail and railroad ties, layering new concrete railroad ties and welding tracks. Another passenger service outage is expected to be planned for later this month to allow for additional track improvements.
