Patsaouras Transit Plaza

Patsaouras Transit Plaza is a bus station on the east side of Union Station in Downtown Los Angeles, near the El Monte Busway. It was originally named the Gateway Transit Plaza but was renamed after Nick Patsaouras, former Rapid Transit District board member who was an advocate for public transportation.

The Metro Headquarters Building is located at the northern end of the plaza.

J Line platform


A new transitway station for the J Line and other transit buses operating on the El Monte Busway, including the Silver Streak, was built south of the Patsaouras Transit Plaza in the median of the El Monte Busway, after years of delays and budget increases.

The station allows buses traveling in both directions on the busway to serve Union Station with a minimum of delay for passengers for other destinations. A bridge allows for passengers to walk directly from the Patsaouras Transit Plaza to the busway station, thereby eliminating a long, convoluted walk across the Union Station property to the former stop located on the El Monte Busway at Alameda.

Construction on the station started in early 2017. Work on the station was halted on April 24, 2018, when archaeological and Native American artifacts were discovered at the site. Archaeological investigation field work was completed nearly a year later on April 12, 2019. Construction resumed in May 2019, with construction completed on November 1, 2020.

The project cost $51 million, well more than double the original estimate. The project was funded by tolls collected as a part of the Metro ExpressLanes project and a grant from the U.S. government.
