Santa Margarita River Bridge Replacement 

SMRBThe Santa Margarita River Bridge dates back to 1916 and is located north of the City of Oceanside within the U.S. Marine Corps Base Camp Pendleton.

This project will replace the existing steel truss single-track railroad bridge across the Santa Margarita River with a new reinforced concrete double-track bridge. Replacement of the bridge with a new bridge constructed with modern materials will substantially reduce future maintenance needs and associated cost.

In addition, adding the second main track will provide more operational flexibility by allowing trains to meet and pass, thereby improving schedule reliability.The bridge’s existing timber trestle approach structure also will be replaced with a pre-cast box girder trestle approach.

Project Updates

The new double-track rail bridge was completed and opened for service Monday, Nov. 18, 2013. TheSMRB bridge Amtrak Pacific Surfliner train rolled over the old steel-truss bridge for the last time around midnight on Friday, Nov. 15. The old bridge, which is visible from Interstate 5, just north of Oceanside, will be demolished in the coming months. The new concrete bridge was completed during the rail shutdown of November 16-17, 2013, and SANDAG appreciates the patience of rail passengers who used bus services throughout the weekend.

The new rail bridge is one of many that will be modernized in the corridor as we work to double-track the corridor to improve the reliability and on-time performance of passenger and freight rail on San Diego’s coastal rail line.
