Construction crews continue to work within the BNSF Railyard as part of the Mt. Vernon Avenue Bridge project. Crews are currently building bents that will support the spans of the new bridge and are working on installing utilities. This work requires using a method known as cast in drilled hole (CIDH), drilling approximately 30’ holes into the ground, which will then be filled with concrete.

Since opening to the public in 1934, the Mt. Vernon Avenue Bridge (MVAB) was an iconic structure, bridging San Bernardino communities to the north and south and serving as a vital link for residents, visitors, students and businesses. The Mt. Vernon Avenue Bridge is a complex bridge replacement project that spans over one of the largest rail yards in the region. An iconic structure in San Bernardino, the Mt. Vernon Avenue Bridge connected communities on the west side of San Bernardino for nearly 90 years, serving as a vital link for residents, visitors, students, and businesses.

To ensure the safety and longevity of the bridge, the City of San Bernardino (City) and the California Department of Transportation (Caltrans) partnered with the San Bernardino County Transportation Authority (SBCTA) to rebuild the bridge. Improvements at the south end of the bridge will include retaining walls along both sides with 3rd Street closed during construction but opened to traffic permanently after construction is complete. On the north side retaining walls will also be constructed along both sides of the transition between the bridge and W. Kingman Street. Where Mount Vernon Avenue reconnects to W. 2nd Street and W. Kingman Street new curbs and gutters will be installed. Reconstruction of the new bridge will begin in 2023 and the new structure is anticipated to open in 2025.
