Since opening to the public in 1934, the Mt. Vernon Avenue Bridge has been 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 community, like the bridge, has seen a great deal of change over the past 86 years.

To ensure the safety and longevity of the bridge, the City of San Bernardino and the California Department of Transportation (Caltrans) partnered with the San Bernardino County Transportation Authority (SBCTA) to rebuild the bridge – a process that will span approximately three years. The bridge closed in December 2020 and disassembly was completed in April 2021. Reconstruction of the new bridge will begin in 2022 and the new structure is anticipated to open in 2024.

Pedestrian Detour
To support pedestrians, bicyclists, and the disabled, with a convenient detour option while the bridge is closed, SBCTA has partnered with Omnitrans to offer a complimentary bus service. To access the complimentary bus service:

  • Step 1: CHOOSE where to begin your trip – at the north end of the bridge, go to the bus stop at 5th Street/Mount Vernon Avenue (Route 3/4 or Route 14); from the south end of the bridge, go to the bus stop at 2nd Street/Metrolink Way (Route 1).
  • Step 2: SAY “Bridge Detour” to the bus driver when you board for the complimentary fare.
  • Step 3: TRANSFER at the Transit Center and continue to Route 1 (exit at 2nd Street/Metrolink Way) or Route 3/4 and Route 14 (exit at 5th Street/ Mount Vernon Avenue) to reach the other side of the bridge.
