OCTA and Metrolink have begun the San Juan Creek Bridge Replacement Project, which will replace the 107-year-old railroad bridge over San Juan Creek in San Juan Capistrano. The project will enhance safety and reduce maintenance needs and the new bridge will meet current design and bridge-load standards. Construction is expected to be completed in 2026.
Once the new bridge is completed, the existing bridge will be demolished and a new foundation and substructure will be constructed in its place for a potential second bridge. San Juan Creek is home to environmentally sensitive wildlife and habitat and the area is difficult to access for construction, so if a future need arises for a second bridge the supporting infrastructure will be in place.
A segment of the San Juan Creek Trail/Vereda Bikeway beneath the bridge is expected to be closed intermittently during construction. A detour has been established using Camino Capistrano, Del Obispo Street and the Trabuco Creek Trail. Sign up for construction alerts to receive the latest information regarding the trail closure.
The $65.6 million project is funded by OC Go, also known as Measure M, a half-cent sales tax for transportation improvements in Orange County, as well as state and federal funds.
For more information, visit the project webpage or stop by project booths over the next few months at Descanso Park or Doheny State Beach to talk with members of the Outreach Team. If you have any questions, email SJCBridge@octa.net.
