Valley Subdivision Bridge and Culvert Improvements Project

The Southern California Regional Rail Authority is undertaking the Valley Subdivision Bridge and Culvert Improvements Project to ensure the continued reliability of Metrolink passenger service by rehabilitating, replacing in-kind, or abandoning 15 drainage structures located within the existing railroad right-of-way. Work will involve a range of activities including minor regrading, replacement of headwalls and wingwalls, installation of new ballast retainers, and extension of culvert pipes, all scoped strictly within current right-of-way boundaries to avoid expansion or encroachment. The project is designed to preserve infrastructure integrity without altering the surrounding land use or rail alignment. This initiative is part of the agency’s broader State of Good Repair efforts and is being managed by Aaron Azevedo, Director of State of Good Repair, who serves as the primary point of contact for inquiries. The forecasting notice was posted on June 2, 2026, indicating future procurement activity, though no solicitation number or set-aside details are currently available. All work will be confined to California, specifically within the Valley Subdivision area, and no additional federal or state funding mechanisms have been disclosed at this stage.
