Rosecrans/ Marquardt Grade Separation

The Rosecrans/Marquardt Grade Separation Project will improve the safety and track flow of the Rosecrans Av/ Marquardt Av intersection. Located in the City of Santa Fe Springs, the Rosecrans/Marquardt grade crossing is traversed by more than 112 freight and passenger trains, and 45,000 vehicles in a 24-hour period. With such heavy through traffic, this intersection has been identified by the California Public Utilities Commission (CPUC) 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 this intersection from the existing diagonal at-grade crossing and substantially enhance the safety and traffic flow on surface streets. It will also improve the efficiency of train movements along the rail corridor.

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

Project Milestones

The 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 preparing an Environmental Assessment (EA) for the Project under the National Environmental Policy Act (NEPA). Metro expects the EA will be completed as anticipated early as Summer 2018, along with an associated Finding of No Significant Impact (FONSI).

Following the completion and filing of an Environmental Assessment Document, the project will move into pre-construction preparations, assuming all funds for property acquisition and construction are secured.
