Division 20 Portal Widening & Turnback Facility Project Map

Metro is making key improvements at the Division 20 Rail Yard, located just south of Union Station near the Arts District, to support faster and more frequent subway service. The Division 20 Portal Widening & Turnback Facility Project adds new trackwork and expands train storage and turnaround capabilities for the B and D Lines.

These upgrades will reduce delays and allow more trains to run during peak hours—which is especially important as ridership grows with the opening of the D Line Extension to the Westside.

Work includes widening the portal tunnel entrance, reconfiguring existing tracks, adding new turnaround facilities, and modifying portions of the yard to support more efficient operations. Additional elements include new power substations, updates to the 1st Street Bridge, and on-site enhancements like lighting, landscaping, and cultural resource mitigation.

The project directly supports future service expansions and helps Metro meet growing demand with more reliable, high-capacity subway service.
