LA County Metropolitan Transportation Authority El Monte Station Expansion

El Monte, California

The El Monte Transit Center, the largest transit center west of Chicago, no longer provided the quantity of bus berths and support facilities necessary to adequately service the increased demand on the center. These issues, coupled with the local traffic congestion hindering bus access to and from the site, meant that Metro needed a more safe and efficient facility.

Maintenance Design Group’s solution structured the phasing of the project, which started with temporary facilities constructed on an existing parking lot. The existing El Monte Transit Center structures were then demolished to make room for the new facility that doubled transfer capacity. The Transit Station design permits patron access to all bus berths without crossing bus circulation paths. To lessen auto/bus congestion by vertical separation, the underground concourse level can be accessed by a bus tunnel. The tunnel also separates all buses from the City grid at this critical juncture. The placement of the Station allows for a future intermodal relationship between it and a future Metro Rail line station.

The facility also accommodates a diverse program of uses, including Metro and regional bus service, as well as Metro’s Fly-Away service and Greyhound service. The facility was designed to accommodate CNG-fueled vehicles by natural ventilation, and includes a state-of-the-art gas detection system.
