Alondra Boulevard Bridge


  • Started: Spring 2012
    Completed: Late 2015

    Cost: $110 million

    Project Overview

    The U-5  Alondra Boulevard Interchange Project was the second of six segments of the I-5 South Corridor freeway widening project to break  ground. It extended from North Fork Coyote Creek to Marquardt Avenue in the City of Santa Fe Springs. Caltrans reconstructed the Alondra Boulevard bridge overcrossing and widened nearly one mile of I-5.

    In April 2012 Caltrans began reconstructing the first half of the 57-year old Alondra Boulevard Bridge and completely demolished the remaining portion in June 2013. The bridge was reopened in August of 2014. It is the largest of three new structures and has been reconstructed and widened from a four-lane to a six-lane bridge, with three lanes in each direction, and lengthened to accommodate a wider freeway. The project added one High Occupancy Vehicle (HOV) and one general purpose lane in each direction, widened shoulders, and constructed a concrete median barrier.
