FlatironDragados’ LA Rail Projects: Southeast Gateway & Link Union Station
FlatironDragados wins $10.5M Southeast Gateway Line preconstruction contract, boosting Los Angeles rail infrastructure.

Introduction
FlatironDragados has been awarded contracts by the Los Angeles County Metropolitan Transportation Authority (METRO) for two rail infrastructure projects, including preconstruction services for the Southeast Gateway Line and the Link Union Station project. The Southeast Gateway Line’s total construction cost is expected to exceed $500 million.
Southeast Gateway Line Project
The Los Angeles County Metropolitan Transportation Authority (METRO) has awarded FlatironDragados contracts for two rail infrastructure projects. FlatironDragados, in partnership with Herzog, will undertake the preconstruction services for the Southeast Gateway Line Enabling project. This initiative involves the relocation of heavy freight rail lines and utilities, paving the way for the future development of 14.5 miles of new light rail in southeast Los Angeles County. The preconstruction contract is valued at $10.5 million and is focused on early design coordination and construction planning. The overall construction for the Southeast Gateway Line is projected to exceed $500 million.
Scope of the Southeast Gateway Line
This project will encompass utility relocations, rail installations, the construction of a new light rail bridge and freight bridge, a pedestrian bridge over the freeway, and a new station located at the I-105 freeway. Upon completion, the Southeast Gateway Line Programme aims to enhance transit access for multiple cities, including Bell, Bellflower, Cerritos, Cudahy, Downey, Florence-Firestone, Huntington Park, Los Angeles, Paramount, South Gate, and Vernon.
Link Union Station Project
Additionally, FlatironDragados has been selected for the preconstruction services phase of the Link Union Station project, which focuses on modernising the historic Los Angeles Union Station. The preconstruction contract for this project is valued at $7 million and will support ongoing collaboration with Metro on design and construction planning. The Link Union Station project aims to create “run-through tracks” within an elevated rail yard, which is expected to increase the station’s capacity by up to 200%.
Project Goals and Objectives
This enhancement is expected to improve transit connectivity, accommodate Amtrak and Metrolink services, and prepare the corridor for future high-speed rail operations. The planned improvements will allow trains to enter and exit from both ends of the station, thereby reducing congestion and improving operational flexibility. In 2023, METRO approved a master cooperative agreement with the City of Inglewood for the 1.6-mile Transit Connector Project.
Conclusion
FlatironDragados has been awarded contracts by the Los Angeles County Metropolitan Transportation Authority (METRO) for the Southeast Gateway Line and the Link Union Station project. The preconstruction contract for the Southeast Gateway Line is valued at $10.5 million, and the total construction cost is expected to exceed $500 million. The Link Union Station project’s preconstruction contract is valued at $7 million.
