Buses on Shoulders Demonstration Project

The I-805/SR 52 Bus On Shoulder Demonstration project has concluded. Caltrans is beginning construction of the HOV/Express lanes along I-805 North (north of SR 52) in the median (HOV lane) and the transit shoulder lanes on the outside shoulder would not provide a location for emergency stops along this section of the freeway.

SANDAG is working with MTS, Caltrans and the U.S. Department of Transportation to implement a new bus on shoulders project along I-805 from Chula Vista using shoulder sections not planned for immediate construction. The new service will provide a time competitive transit alternative for travel between Chula Vista, City Heights, and the UTC area.
