SBCTA, Caltrans, and City of Highland celebrate completion of SR 210 Lane Addition and Base Line Interchange Project

On July 21, 2023, SBCTA in partnership with Caltrans and the City of Highland celebrated the completion of the SR 210 Lane Addition and Base Line Interchange Project with a ribbon cutting ceremony along the new Base Line interchange in the City of Highland.

The lane addition on SR 210, improvements at Base Line Interchange as well as the pavement rehabilitation began construction in February 2020. Thanks to a use of state and local (including Measure I) funding, SBCTA, in cooperation with Caltrans and the City of Highland, constructed the three projects concurrently to reduce the overall impact to the public. The project improved the quality of the roads and traffic flow for the residents and businesses of San Bernardino, Highland, and Redlands, as well as an unincorporated portion of San Bernardino County.

The SR 210 Lane Addition and Base Line Interchange Project is entering its final month of construction. In early July, crews restriped the SR 210 lanes to their final configuration between Del Rosa Avenue and the I-10 freeway, adding one mixed-flow lane in each direction between Highland Avenue and San Bernardino Avenue, auxiliary lanes (merge lanes) between Base Line and 5th Street/Greenspot Road, and an acceleration lane at the 5th Street/Greenspot Road eastbound ramp.

SBCTA anticipates regularly scheduled nighttime closures to continue through July, and intermittent nighttime closures to continue through August as crews complete clean-up work throughout the project corridor. All work is expected to be complete by the end of August.
