National Infrastructure Project Assistance (Mega) Program

General Grant Program Information

The National Infrastructure Project Assistance (Mega) Program was created in the Bipartisan Infrastructure Law (BIL) to fund major projects that are too large or complex for traditional funding programs and are likely to generate national or regional economic, mobility, or safety benefits. It is a highly competitive program.

USDOT is combining three major discretionary grant programs—for the Mega, INFRA, and Rural Surface Transportation Grant (Rural) programs—and two fiscal years of funding into one Multimodal Projects Discretionary Grant (MPDG) opportunity to reduce the burden for state and local applicants and increase the pipeline of “shovel-worthy” projects that are now possible because of BIL.

A benefit-cost analysis (BCA) is required for these grant programs. For more information about BCAs, see What Is a BCA? and USDOT's Benefit-Cost Analysis Guidance for Discretionary Grants.
