Metro - Division 20 Portal Widening & Turnback Facility

Metro is anticipating a greater demand for frequency of the Red and Purple lines, with the extension of the Purple line currently in construction. The purpose of this $500 million project is to reduce the minimum headway for the Red and Purple lines from five minutes to two minutes.

The project aims to accommodate increased service levels on the Metro Red/Purple Lines. To achieve this, Metro is planning facility improvements, including a widening of the heavy rail tunnel south of the US-101 freeway (Portal Widening) and a new turnback facility (Turnback Facility) in the Division 20 rail yard. With these improvements, new tracks and switches will allow for improved service times at Union Station and throughout the Metro Red/Purple Line system.

Metro Red and Purple Lines currently carry more than 140,000 passengers each day, with ridership expected to grow by 49,000 when the Metro Purple Line is extended to the Veteran Affairs West Los Angeles Medical Center. Many Red/Purple Line trains switch tracks before entering Union Station, which is the reason that some trains operate more slowly coming in and out of the station. This project will allow switching to take place after riders get on or off trains, allowing for faster service times. It will also help to ensure safety and reliability on the system, a sufficient capacity to serve future passengers and a more effective operation of Metro's expanding subway network.

KKCS is responsible for preparing the Construction Staging Schedule and cost estimates for the project.
