Week of March 1, 2021
BRIDGE WORK
The week of March 1, crews will continue work on the retaining walls along the EB SR 210 Base Line on-ramp and the WB SR 210 on-ramp at Base Line, perform a concrete pour on SR 210 at 5th Street, and begin constructing temporary bridge supports, also known as falsework, at Highland Avenue and Arden Avenue. The following nighttime closures of EB and WB SR 210 are needed to facilitate this work:

  • EB SR 210 Closed from 5th Street to San Bernardino Avenue: Closed nightly from 10:00 p.m. to 5:00 a.m., Tuesday, March 2 through Thursday, March 4 (into Friday morning). DETOUR: Exit EB SR 210 at 5th Street and turn right at the end of the ramp, turn left on Alabama Street, then turn left on San Bernardino Avenue to reenter EB SR 210 via the on-ramp.

ABOUT THE PROJECT
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.
