Train traffic is now traveling over the newly constructed San Juan Creek Bridge in San Juan Capistrano, California.
Following testing over the past weekend, the first passenger trains traveled over the new bridge, built next to the previous bridge, beginning early Monday morning. The new bridge replaces a structure built in 1917 and serves as a key link along the Los Angeles–San Diego–San Luis Obispo rail corridor, one of the busiest intercity passenger-rail lines in the nation, according to an Orange County Transportation Authority (OCTA) press release.
Funded by the Measure M half-cent sales tax for transportation improvements and state and federal funds, the $65 million project enhances the structural integrity of the corridor while reducing ongoing maintenance costs, OCTA officials said.
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.
“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.
