South Bay Rapid  Construction

Construction is underway on the South Bay Rapid Project, a new level of transit service that will include 12 stations along a 26-mile route from the Otay Mesa Port of Entry to Downtown San Diego via eastern Chula Vista, connecting employment and activity centers in Downtown San Diego and South County. Rapid service in the South Bay is expected to begin in 2018. Ongoing construction may temporarily impact motorists along the South Bay Expressway. 

Construction continues on the South Bay Rapid project in Chula Vista. Work is now underway on the dedicated transit bridge over the South Bay Expressway between Birch Road and Olympic Parkway. As part of bridge construction, the South Bay Expressway will be closed in both directions overnight between Birch Road and Olympic Parkway in Chula Vista on Monday, April 24, from 9 p.m. to 5 a.m., to accommodate installation of falsework, or temporary wood structures used to support the bridge foundation. During the closure, the northbound on- and southbound off-ramps at Birch Road and the northbound off- and southbound on-ramps at Olympic Parkway also will be closed. Additional overnight northbound and southbound lane closures are planned for April 25-27. 

When completed, the new bridge will allow transit vehicles to cross the South Bay Expressway while maintaining high-frequency, limited-stop service. Additionally, the guideway bridge will improve walking and biking access by connecting residents and communities west of the toll road with retail and entertainment options on the east side. As construction of the guideway bridge continues, motorists can expect temporary lane closures, detours, reduced lane widths, some night and weekend work, equipment and signage, and construction vehicles traveling in and out of the median and along the outside shoulder in the construction area.
