The National Culvert Removal, Replacement, and Restoration Grant Program (Culvert Aquatic Organism Passage (AOP) Program) is a competitive grant program that awards grants to eligible entities for projects for the replacement, removal, and repair of culverts or weirs that meaningfully improve or restore fish passage for anadromous fish.
On June 25, 2024, FHWA announced the availability of at least $196 million for FY2023 Culvert AOP grants as part of the FY23-26 Culvert AOP NOFO. The deadline to apply for FY23 funding via Grants.gov is Monday, September 23, 2024, at 11:59 p.m., EDT.
