The FY 2025-2026 MPDG program, under the Department of Transportation’s Office of the Secretary, offers three separate grant programs: the National Infrastructure Project Assistance grants program (Mega), the Nationally Significant Multimodal Freight and Highway Projects grants program (INFRA), and the Rural Surface Transportation Grant program (Rural). This opportunity collectively allocates approximately $5.1 billion in funding to support significant surface transportation infrastructure projects, such as highway and bridge improvements, railway-highway grade crossing enhancements, wildlife crossings, public transportation advancements, and more. The MPDG aims to fund projects that demonstrate substantial national or regional impacts or address critical needs in rural transportation infrastructure. The application deadline is set for May 6, 2024.
