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. Built in 1917, the bridge has reached the end of its useful life.

The project will construct a new three-span, girder bridge west of the existing bridge to 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 because there may be a need, a foundation and substructure for a bridge will be constructed.

The bridge services 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

San Juan Creek Trail Closure

The San Juan Creek Trail/Vereda Bikeway will be closed in the project area, between Camino Capistrano and where the two trails meet west of the railroad. The trail is expected to be closed for up to 30 months.

A detour will be established using Camino Capistrano, Del Obispo Street and the Trabuco Creek Trail. The detour is the safest, most direct route around the closure and has been approved by the City of San Juan Capistrano.
