Rosecrans/Marquardt Grade Separation Project

The Rosecrans/Marquardt Grade Separation Project will improve the safety and track flow of the Rosecrans Avenue and Marquardt Avenue intersection. Located in the City of Santa Fe Springs, the Rosecrans/Marquardt grade crossing is traversed by more than 100 freight and passenger trains, and 45,000 vehicles in a twenty-four-hour period. The intersection has been identified by the California Public Utilities Commission as the most hazardous grade crossing in the State. Providing a grade separation will significantly improve safety, eliminate delays, and enhance the environment.

The proposed project will grade separate the Rosecrans/Marquardt intersection from the existing diagonal at-grade crossing and substantially enhance the safety and traffic flow on surface streets. The proposed project would elevate Rosecrans Avenue to an overpass, which would allow critical improvements along the roadway and BNSF Railway (BNSF) right-of-way to occur.

This project is led by Metro in cooperation with the City of Santa Fe Springs, City of La Mirada, BNSF, California Department of Transportation (Caltrans), Amtrak, California Public Utilities Commission (CPUC), Metrolink, California High-Speed Rail Authority (CHSRA), and the Federal Railroad Administration (FRA).

The Rosecrans/Marquardt Grade Separation Project was selected for a $15 million 2016 Transportation Investment Generating Economic Recovery (TIGER) grant. FRA is administering TIGER funds for the construction of the Project.

Environmental Assessment (EA)

This project was environmentally cleared under the California Environmental Quality Act (CEQA) with a Statutory Exemption filed with the California Governor’s Office of Planning and Research in February of 2016.

Metro is currently working with FRA to prepare an Environmental Assessment (EA) for the project to comply with the National Environmental Policy Act (NEPA). The NEPA process must be completed before any construction work can begin.

The Draft EA will be available for a thirty-day comment period, from May 16 to June 15, 2018. The Draft EA will be available to review online at Metro’s project website. A copy of the document is also posted here.

After the comment period is over, Metro and FRA will continue the NEPA process to finalize the document.
