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.
