*In addition to regularly scheduled nightly closures, the WB SR 210 on- and off-ramps at San Bernardino Avenue will be closed for 55-hours from Friday, April 14 at 10:00 p.m. to Monday, April 17 at 5:00 a.m. during the WB SR 210 55-hour directional freeway closure.

Please note, nighttime lane/ramp closures may occur intermittently along EB and WB SR 210, between Del Rosa Avenue and I-10, Mondays through Saturdays (into Sunday mornings), from 8:00 p.m. to 6:00 a.m. No two consecutive ramps will be closed at the same time. In addition, crews will continue daytime and nighttime construction activity along SR 210 as well as on local city streets.

Please note, Highland Avenue and Arden Avenue will not be closed simultaneously.

In August 2022, the EB SR 210 crossover lane was removed, and the traffic was shifted to the newly paved lanes on EB SR 210.

As part of this new transition, crews installed concrete barriers along EB SR 210 from San Bernardino Avenue to the EB/WB I-10 connectors to safely separate travel lanes from adjacent work areas. In this configuration, motorists entering EB SR 210 using the on-ramp at San Bernardino Avenue are not able to access the EB I-10 connector and will be automatically directed onto WB I-10. This configuration will be in place for approximately four to five months. 

EB SR 210 to EB I-10 Suggested Detour: 

• From San Bernardino Avenue travel south on Tennessee Avenue and turn left onto the EB I-10 on-ramp to access the freeway. 

Construction of new sound walls and/or retaining walls is underway throughout the project corridor. This work is ongoing Mondays through Saturdays during daytime hours (6:00 a.m. to 4:00 p.m.) and intermittently during nighttime hours (9:00 p.m. to 5:00 a.m.). 

For more information on sound wall and retaining wall construction, please call (877) 55-SBCTA or email info@goSBCTA.com.

The SR 210 Lane Addition and Base Line Interchange Project is designed to provide increased traffic flow throughout this corridor. To eliminate the existing bottleneck and provide lane continuity, the SR 210 will be widened from Sterling Avenue to San Bernardino Avenue in the cities of San Bernardino, Highland, and Redlands, as well as an unincorporated portion of San Bernardino County. Base Line Interchange will also be widened from Buckeye Street to Seine Avenue in the City of Highland, which will include widening three of the four interchange ramps. As the SR 210 Lane Addition and Base Line Interchange projects aligned geographically and shared similar delivery schedules, they were combined for the design, right-of-way, and construction phases to save cost and expedite the schedule. In addition, pavement rehabilitation work was added through a cooperative agreement with Caltrans that includes new concrete pavement between 5th Street and Lugonia Avenue. Adding the pavement rehabilitation work during the Lane Addition and Base Line Interchange projects means one less project that the community will have to navigate around in the future.

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