The San Bernardino County Transportation Authority (SBCTA) is pleased to announce the start of construction to replace the Mount Vernon Avenue Bridge (MVAB).
On Monday, December 21, 2020 (subject to change), Mount Vernon Avenue is scheduled to close; there will be no through access permitted across the bridge, between 2nd Street and 5th Street. Please note, businesses will remain open during construction and access to businesses on Mount Vernon Avenue at 2nd Street and 5th Street, and on Mount Vernon Avenue between W. Kingman Street and 5th Street, will be maintained.
Over the next few weeks, crews will prepare for the closure of the Mount Vernon Avenue Bridge (MVAB).
Digital message boards, detour signs, and arrow boards will be installed along the motorist detour route (shown in green on the map below). Work will also be completed to adjust signal timing and roadway striping at key intersections along the detour route, including Mount Vernon Avenue and Rialto Avenue, Rialto Avenue and G Street, H Street and 5th Street, 5th Street and Mount Vernon Avenue, and Mount Vernon Avenue and 2nd Street. Additionally, crews will install fencing and concrete barricades, also known as k-rail, when it comes time to close the bridge to traffic.
When the bridge closes, there will be no direct access for motorists, pedestrians, or bicyclists who wish to cross Mount Vernon Avenue between 2nd Street and 5th Street. 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. Bus stop locations nearest the MVAB are shown on the map below, for Route 1
(Mount Vernon and 2nd Street) and Route 14
(Mount Vernon and 5th Street). Pedestrians wishing to access the complimentary service can board the bus at the stops below. Be sure to mention "Detour/Desvío" to the bus driver upon boarding for the special complimentary fare. For more information about the pedestrian/bicyclist bus detour please contact us at by calling 877-55-SBCTA or email info@goSBCTA.com.
Following closure of the bridge, crews will begin the careful work of disassembling the bridge over a period of a few months, into early 2021. Reconstruction of the new bridge will begin in 2022 and the new structure is anticipated to open to the public in 2024.
