The closures listed below are required next week to facilitate work on the I-10/Cedar Avenue Interchange Project:

The following closures will take place nightly from 9:00 p.m. to 5:00 a.m., Sunday, April 21 through Thursday, April 25 (into Friday morning):

• EB I-10 lane closures between Sierra Avenue and Riverside Avenue, at least one lane will remain open at all times

Construction will generally occur Monday through Friday during daytime (6:30 a.m. to 3:00 p.m.) hours and Sunday through Thursday during nighttime (8:00 p.m. to 5:00 a.m.) hours. At times, this work may be loud or cause dust and vibration. Traffic delays are expected. Motorists are encouraged to plan ahead, allow extra time to reach your destination or use alternate routes if possible.

All construction is dynamic and the schedule is weather-permitting and subject to change. Visit the Google map above (project Google map) for the most up-to-date closures scheduled and available detour routes.

Motorists traveling southbound (SB) on Cedar Avenue are prohibited from making a left turn on to Orange Street.

This configuration started in June 2023 and is expected to be in place for approximately 18 months while crews work to widen the Cedar Avenue bridge. The recommended detour route is shown in green on the map below.

The Cedar Avenue Bridge over the I-10 and the railroad tracks will be widened in two stages. Traffic has been shifted onto the west half of the bridge and crews partially demolished the east half of the bridge in mid April 2023. Work to reconstruct and widen this portion of the bridge will continue through summer 2024.

To accommodate this shift, Cedar Avenue has been reduced by one lane in each direction between Orange Street and Valley Boulevard. 

• Northbound (NB) Cedar Avenue has one through lane (with access to the EB I-10 on-ramp), and one dedicated left turn lane onto the WB I-10 on-ramp.

• S Cedar Avenue has one dedicated right turn lane onto the WB I-10 on-ramp, one through lane, and one dedicated left turn lane onto the EB I-10 on-ramp.

Motorists are encouraged to use alternate routes. Traffic delays should be expected during bridge reconstruction, please allow extra time to reach your destination and use caution when traveling through work zones. While the east side of the bridge is under construction, pedestrian access will be maintained across the west side of the bridge.

Once reconstruction of the east side of the bridge is completed, crews will then perform bridge widening along the west side, tentatively scheduled to begin in summer 2024.

The city of Rialto will hold an Earth Day Event on, April 20, from 8:00 a.m. to 1:00 p.m. Click the image below for more information on events in Rialto.

The I-10/Cedar Avenue Interchange Project is designed to relieve congestion, enhance safety, and improve traffic operations along Cedar Avenue between Bloomington Avenue and Orange Street. The project will widen the I-10 overcrossing and replace the railroad bridge, provide for roadway improvements along Cedar Avenue, and add capacity to the on- and off-ramps from Cedar Avenue to the I-10. During construction activities may include removing and rebuilding of existing and new structures, digging up roads for utility work, pavement and restriping work, installation of new traffic signals, traffic shifts, intermittent lane closures, and ramp closures. Workers and heavy equipment will be present throughout the project corridor and we ask that you allow for extra time to reach your destination as you may experience delays.

Please remember construction is dynamic and the schedule is subject to change.
