SANTA MARGARITA – On Monday, May 13, 2024, the County of San Luis Obispo will begin work to replace the bridge on El Camino Real at Santa Margarita Creek between Santa Margarita and Atascadero.

The public can expect reduced speeds and delays of up to 10 minutes through the construction zone until November 2024.

This project will replace a bridge that has reached the end of its useful life and will improve roadway safety by providing a new center turn-lane and adding wider paved shoulders for vehicle and bicycle safety. Work will also include a left-turn lane at the intersection of Asuncion and Santa Margarita roads and the reconstruction of a portion of those roads near the bridge.  

The first part of the project will involve constructing a temporary detour bridge adjacent to the existing bridge, which will take approximately one month. Once the detour bridge is in place, traffic will be diverted around the existing bridge through a 15-mph detour. After the existing bridge is demolished, the new bridge will be constructed in its place. Traffic will be re-routed onto the new bridge and the temporary bridge will be removed in the Fall of 2024. 

In addition to the bridge replacement, the project will relocate a portion of the Nacimiento Water Pipeline from the existing pipe bridge into the new bridge structure. 

Souza Construction has been awarded a contract for $6.9 million to perform the work. The project is funded by the Federal Highway Administration via grant funding administered by Caltrans and local funds.
