San Juan Creek rail bridge strengthens Southern California corridor
29.10.2025
The San Juan Creek rail bridge has officially opened in San Juan Capistrano, marking a major milestone for the Orange County Transportation Authority (OCTA) and Metrolink as they continue to modernize Southern California’s rail network.
This is reported by the railway transport news portal Railway Supply.
San Juan Creek rail bridge — scope and funding
OCTA and Metrolink replaced the original bridge built in 1917, which had exceeded its service life and required modernization.

The new structure supports both passenger and freight traffic while ensuring safer, more reliable operations through the area.
According to OCTA, the total project investment reached $65.6 million, financed through Measure M — Orange County’s voter-approved half-cent sales tax for transportation — with additional state and federal participation.
Construction progressed efficiently, minimizing disruption to rail service on one of the busiest coastal routes in the United States.
San Juan Creek rail bridge — significance for the LOSSAN corridor
The bridge forms part of the Los Angeles – San Diego – San Luis Obispo (LOSSAN) corridor, which serves millions of passengers annually and provides a crucial freight connection along California’s coast.
By upgrading this key link, OCTA and Metrolink enhance network reliability and strengthen climate resilience for future operations.
Train traffic began running over the new bridge in late 2025 following successful testing.
Demolition of the 1917 structure is scheduled for spring 2026, once all operations have fully transitioned.
This replacement marks another step in OCTA’s long-term plan to improve rail safety, efficiency, and environmental sustainability across Orange County.
