Train traffic is now traveling over the newly constructed San Juan Creek bridge in San Juan Capistrano, marking a major milestone in OCTA’s ongoing efforts in partnership with Metrolink to enhance rail safety and reliability.
On October 27, the first passenger trains traveled over the new bridge, built immediately adjacent to the previous bridge. The new bridge replaces a structure originally built in 1917 and serves as a key link along the Los Angeles–San Diego–San Luis Obispo (LOSSAN) rail corridor, one of the busiest intercity passenger rail lines in the nation.
“This new bridge represents an important investment in safety and efficiency for the thousands of passengers and freight customers who depend on this rail line every day,” said OCTA Chair Doug Chaffee. “By replacing an aging structure that has served the region for more than a century, we’re ensuring that train service through this area remains reliable and resilient for decades to come.”
The approximately $65-million project, funded by state and federal funds and Measure M, Orange County’s half-cent sales tax for transportation improvements, enhances the structural integrity of the corridor while reducing ongoing maintenance costs.
The new bridge features modern design standards that improve rail operations and safety, including upgraded foundations and improved flood protection for the San Juan Creek channel below.
The San Juan Creek Bridge Replacement Project is part of OCTA’s ongoing commitment to maintaining and modernizing Orange County’s rail infrastructure to support a safe, efficient, and sustainable transportation network.
