Bridge Corrosion Prevention and Repair Act of 2025

HR 4170 requires federally funded bridge projects (including highway and railroad bridges) to use certified contractors trained in corrosion prevention. It mandates that contractors employ workers certified through qualified training programs meeting industry standards (like ANSI/NACE) for tasks like surface preparation, coating application, and hazardous material removal. The bill also expands federal grant eligibility to include corrosion control work on rail bridges and directs the Transportation Secretary to study best practices for inspecting and repairing weathering steel bridges within 18 months. These changes directly affect bridge contractors, federal agencies managing infrastructure funding, and state/local bridge maintenance entities.
