SR 210 Lane Addition and Base Line Interchange Underway

April 6, 2020

On February 26, SBCTA, Caltrans and the City of Highland broke ground on the SR 210/Lane Addition and Base Line Interchange project to help eliminate the existing bottleneck in the cities of Highland, Redlands, and San Bernardino.  The project will add one mixed-flow lane in each direction between Highland Avenue and San Bernardino Avenue, auxiliary lanes (merge lanes) between Base Line and 5th Street, and an acceleration lane at the 5th Street eastbound ramp. 

Construction commenced quickly and the team is performing various activities to prepare for the bridge widening needs in the median of SR 210.  Activities in the works include excavating for foundation work at 5th Street/Greenspot Road, Pioneer Avenue, Victoria Avenue, City Creek Road, and Base Line Street, and pile driving and installation of concrete barriers along the freeway and at city streets below the freeway.  Crews are working at night to restripe eastbound and westbound SR 210 between Del Rosa Avenue and I-10 to shift lanes several feet toward the outside of the freeway to allow extra work area in the median.
