I-10 Cedar Avenue
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 complete the east side of the bridge over the I-10 freeway in Summer 2025.
During reconstruction, 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.
Following the reconstruction of the west side of the bridge, crews will complete work on the railroad bridge through Winter 2026, rehabilitate Cedar Avenue from Winter 2026 to Spring 2027, and implement erosion control measures at the interchange by Mid-2027.
Left-Turn Restriction: Southbound Cedar Avenue on to Orange Street
Motorists traveling southbound on Cedar Avenue are prohibited from making a left turn on to Orange Street while the Cedar Avenue Bridge is under construction. The recommended detour route is shown in green on the map below.
