NEW: Upcoming Construction Activities At 12th & Imperial Transit Center 

The week of March 11, SANDAG will begin work at the 12th & Imperial Transit Center in Downtown San Diego to replace concrete pavers on the platforms. Work will take place Monday through Friday, 7 a.m. to 3:30 p.m., and is expected to be completed this summer.

Construction will be completed in phases to allow passenger loading onto the Trolley throughout the project. Phase 1 work will begin at the east and west platforms. Once crews complete work at the two outer platforms, they will move to the center platforms in Phases 2 through 4. Regular Trolley service will be maintained at all times. 

Signage will be in place to direct pedestrians. Riders are encouraged to take extra precaution when exiting the train and transferring at the station.    


Project Overview

After more than 30 years of successful operation, the San Diego Trolley has completed a sweeping overhaul of its Blue and Orange Lines and freight line facilities. With the $660 million project complete, passengers and freight carriers enjoy more efficient and reliable services.

TrolleyThe project included: raising platforms, replacing old rail and overhead wires, retrofit/replacement of traction power substations, and improving switching, signaling, and crossovers. New low-floor Trolleys and new station amenities were all part of the project to update the system.
The realignment of the Green Line now allows riders to travel from Mission Valley to the Convention Center or PETCO Park without transferring.
