Bus Only

Bus Only Lane

Operations began on March 11, 2018, for the State Route 15 (SR 15) Mid-City Centerline Rapid Transit Stations project, San Diego’s first freeway-level transit station at University Avenue and El Cajon Boulevard along SR 15. 

In addition to the freeway-level transit stations, the project constructed San Diego Metropolitan Transit System (MTS) bus-only lanes within the existing median of SR 15 from just north of Interstate 805 (I-805) to just south of Interstate 8 (I-8) to help improve on-time performance between the existing Rapid and local transit routes. 

The top priority for SANDAG, Caltrans, MTS, and CHP is roadway safety, and every precaution is being taken to ensure the protection of motorists, commuters, and other travelers in the area. 

Using the MTS bus-only lanes and station platforms as intended is the best way to ensure safety for all. 

  • Drivers on SR 15 – Do not attempt to enter the MTS bus-only lanes at any time. Unauthorized vehicles that attempt to travel in these MTS bus-only lanes will be cited with a $401 fine.
  • Transit Riders/Pedestrians – Do not attempt to walk onto the MTS bus-only lanes at any time. Transit riders who walk onto the MTS bus-only lanes are also subject to a fine.
