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.

Final Initial Study with Mitigated Negative Declaration/Environmental Assessment with Finding of No Significant Impact RAMP CLOSURES FOR NIGHTTIME PAVEMENT WORK ON CEDAR AVENUE
WHAT’S HAPPENING: Crews are scheduled to perform nighttime pavement work on Cedar Avenue as part of the I-10 Cedar Avenue Interchange Improvements Project. Work will include removing the top layer of existing pavement and placing new asphalt.
To safely complete this work, traffic on Cedar Avenue will be maintained by shifting vehicles between the inside and outside lanes as crews work in phases. During construction hours, the Westbound (WB) I-10 on- and off-ramps at Cedar Avenue and the eastbound (EB) I-10 on-ramp at Cedar Avenue will be closed while this work is performed. The eastbound (EB) I-10 off-ramp at Cedar Avenue will remain open; however, motorists will only be able to turn right onto southbound Cedar Avenue. Posted detour signs will guide drivers around the ramp closures.
WHEN: Nighttime pavement work is scheduled nightly from 8:00 p.m. to 5:00 a.m., Wednesday, July 22, through Friday, July 24 (into Saturday morning).
WHAT TO EXPECT: Construction activities may generate noise, dust, vibration, and increased truck traffic in the work area. Crews may utilize paving equipment, excavators, loaders, haul trucks, water trucks, rollers, and other construction vehicles. Motorists should expect traffic delays, follow posted detour signage, and allow additional travel time when traveling through the area.
LANE AND RAMP CLOSURES ON EB I-10
- EB I-10 Lane Closures (Between Sierra Avenue and Pepper Avenue): Nightly Lane closures will take place from 9:00 p.m. to 5:00 a.m. Sunday, July 19 through Thursday, July 23 (into Friday morning). At least one lane will remain open at all times.
