Purple Line Light Rail Project

Purple Line Transit Partners, comprising Fluor, Meridiam Infrastructure Purple Line, LLC, and Star America Purple Line, LLC, reached financial close to design, build, finance, operate and maintain the Purple Line Light Rail project for the Maryland Department of Transportation (MDOT) and the Maryland Transit Administration (MTA).

Fluor is participating in the entire 36-year life cycle of the $5.6 billion project.


Client's Challenge

Located in the Washington Metropolitan Region, one of the most highly congested corridors in the nation, the project includes 21 stations along a 16-mile alignment extending from Bethesda, Maryland, in Montgomery County to New Carrollton, Maryland, in Prince George's County.

This new line will provide connections to several existing transit providers and improve mobility to major economic and job centers, as well as the University of Maryland in College Park.

Fluor's Solution

Fluor is the managing partner of the design-build team, Purple Line Transit Constructors, comprised of Fluor Enterprises Inc., The Lane Construction Corporation and Traylor Bros., Inc. Following the construction, Purple Line Transit Operators, a Fluor-led team comprising Fluor Enterprises, Inc., Alternate Concepts, Inc., and CAF USA, Inc., will provide 30 years of operations and maintenance services.

The Purple Line project is the second transit public-private partnership (P3) project in the United States, following Fluor's success on the pioneering Eagle P3 Commuter Rail Line in Denver, Colorado.



​The Purple Line Light Rail project broke ground in August 2017. ​The groundbreaking was capped off with the sig​ning of the U.S. Department of Transportation Federal Transit Administration's Full Funding Grant Agreement of $900 million from its Capital Investment Grant Program.

Crews began blasting operations in November 2018 and reached a major milestone in December, successfully excavating the first phase of the 1,020-foot Plymouth Tunnel.
