New Bridge in San Juan to Improve Rail Reliability Along LOSSAN Corridor

Train traffic has begun operating across the brand-new Suan Juan Creek Bridge in San Juan Capistrano, marking the replacement of a bridge that had been in place for more than 100 years.

The new bridge was installed as part of a project led by the Orange County Transportation Authority (OCTA) in partnership with Metrolink, and is expected to strengthen rail reliability along Southern California’s Los Angeles–San Diego–San Luis Obispo (LOSSAN) rail corridor.

Constructed adjacent to the original bridge (which was built in 1917); the new 65 million USD bridge was funded through a combination of local, stage and federal sources, including Orange County’s voter-approved Measure M half-cent sales tax for transportation improvements.

The project also included the installation of upgraded foundations and improved flood protection for the San Juan Creek below.

OCTA Chair Doug Chaffee., said:

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.

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.
