SR 210 Lane Addition and Baseline Interchange Project Ribbon-Cutting Ceremony

July 10, 2023

On Friday, July 21, 2023, SBCTA will celebrate the completion of the SR 210 Lane Addition and Base Line Interchange Project.

The project, which broke ground in February 2020, is entering its final months of construction. Crews have striped 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.

Regularly scheduled nighttime closures are anticipated to continue through July, and intermittent nighttime closures will continue through August as crews complete clean-up work throughout the project corridor. Details about nighttime closures are available on the project page of the website. All construction work is expected to be completed by the end of August.

The public is encouraged to join in the celebration of this transportation accomplishment at the upcoming Ribbon-Cutting Ceremony!

When: 10 a.m., Friday, July 21, 2023

Where: 27727 Base Line, Highland (Pluto Street cul-de-sac adjacent to ARCO); parking available on Pluto Street
