Completion

The San Bernardino County Transportation Authority (SBCTA), the County of San Bernardino, City of Fontana, and City of Rialto will improve Cedar Avenue between Bloomington Avenue and Orange Street in the unincorporated community of Bloomington. As a major north-south arterial that experiences high levels of traffic congestion resulting in low levels of service, the project is designed to relieve congestion, enhance safety, and improve traffic operations. The project will:

Widen Cedar Avenue from six lanes to 10 lanes
Provide new bridge railings and sidewalks on Cedar Avenue
Replace Cedar Avenue over the train tracks
Add additional lanes at the on- and off-ramps

Cedar Avenue Bridge Reconstruction

The Cedar Avenue Bridge over the I-10 and the railroad tracks will be widened in two stages. Crews will partially demolish the east side of the bridge in February 2023 and will work to reconstruct and widen bridge through December 2023.

During reconstruction, traffic will be shifted to the opposite side (west half) of the bridge to allow crews to safely widen the structure. To accommodate this shift, one lane will be reduced in each direction on Cedar Avenue between Orange Street and Valley Boulevard. Alternate routes will include Slover Avenue or Valley Boulevard to Riverside Avenue to the east and Sierra Avenue to the west. Traffic delays should be expected during bridge reconstruction, please allow extra time to reach your destination and use caution when traveling through work zones. Following the reconstruction of the east side of the bridge, crews will perform the same activities on the west side of the bridge.

Right-Turn Restriction from Orange Street onto Cedar Avenue

As early as Thursday, March 9, motorists on Orange Street will be prohibited from making a right turn onto NB Cedar Avenue. This configuration will be place for approximately one year while crews work to widen the east side of the Cedar Avenue bridge. The recommended detour route is shown in green on the map below.
