Centerline project mapConstruction is underway on the SR 15 Mid-City Centerline Rapid Transit Stations project, which will build San Diego’s first freeway-level transit stations along State Route 15 (SR 15) at University Avenue and El Cajon Boulevard. The project also will construct transit-only lanes within the existing median from just north of I-805 to just south of I-8. This will help improve on-time performance between the existing Rapid and local transit routes. The new stations will be open in 2017.

As crews work to build the new station platforms and dedicated Rapid transit lanes, nearby residents and businesses can expect intermittent noise during the day and at night in construction areas. Motorists and transit riders can expect intermittent traffic delays and are encouraged to give themselves more time to reach their destination. For transit information visit

SR 15 Commuter Bikeway

In conjunction with the transit stations project, SANDAG and Caltrans broke ground in March 2016 on a $14 million bike project along the SR 15 corridor. The SR 15 Commuter Bikeway will be a safe and direct bike route connecting Mid-City communities with the major retail, commercial, education, and entertainment destinations in the city’s Mission Valley community. The bike path is anticipated to open in spring 2017. View more information on this project.
