I-10 Cedar Avenue

Project Overview
The San Bernardino County Transportation Authority (SBCTA), the County of San Bernardino, City of Fontana, and City of Rialto are improving 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.
The first stage, crews will complete the east side of the bridge over the I-10 freeway. During this time, traffic will be shifted to the opposite side (east half) of the bridge to allow crews to safely reconstruct the sidewalk and concrete barrier on the west half of the structure. To accommodate this shift, one lane will remain reduced in each direction on Cedar Avenue between Orange Street and Valley Boulevard. Traffic delays should be expected during bridge reconstruction, please allow extra time to reach your destination and use caution when traveling through work zones. Alternate routes will include Slover Avenue or Valley Boulevard to Riverside Avenue to the east and Sierra Avenue to the west. Crews are also completing bridge reconstruction of Cedar Avenue over the railroad tracks.
Following the reconstruction of the east side of the bridge, traffic will shift to the newly constructed portion of the bridge to allow for reconstruction of the west side of the bridge.
