Opportunity Information: Apply for NIPA 23 24 MEGA
The Mega Grants opportunity is part of the U.S. Department of Transportation's push, under the Bipartisan Infrastructure Law, to move more large, ready-to-advance transportation projects from planning into construction. DOT is packaging this funding through a combined Multimodal Projects Discretionary Grant (MPDG) approach, which rolls multiple major discretionary programs into one application framework. The idea is to cut down on application burden for state and local governments while building a stronger pipeline of "shovel-worthy" projects. In practical terms, the program is aimed at investments that can create well-paid jobs, strengthen economic growth, reduce transportation-related emissions, improve safety, increase system resilience, and expand transportation options, especially in rural areas and communities that have historically been underserved. DOT also frames these investments as a way to strengthen supply chains and reduce costs that ultimately affect American households.
At the center of this specific opportunity is the National Infrastructure Project Assistance (MEGA) program, which was created specifically because some infrastructure projects are simply too large, too expensive, or too complex to fit neatly into traditional transportation funding programs. MEGA is designed to fund major, high-impact projects that matter at a national or regional scale, especially those that span multiple jurisdictions (for example, crossing city or county lines) or function as part of a larger regional network. Another key feature is that projects can be multimodal, meaning they can involve more than one type of transportation system. Eligible project types are broad and include highways and major roadway improvements, bridges, freight and goods movement projects, ports, passenger rail, and related public transportation infrastructure that rises to the level of national or regional significance.
A major defining feature of MEGA is the scale of projects it targets. DOT expects to split the program's funding roughly into two tiers based on total project cost: about half of the funding is intended for projects with costs greater than $500 million, and about half is intended for projects costing more than $100 million but less than $500 million. This structure signals that the program is specifically aimed at big-ticket capital projects, not smaller standalone improvements. The opportunity listing also shows a very high potential maximum award size (an award ceiling of up to $1 billion), reinforcing that MEGA is built for unusually large infrastructure needs.
Eligibility is also intentionally broad so that different types of public entities can apply or partner depending on how a project is structured. Eligible applicants include a state or group of states; metropolitan planning organizations; local governments; political subdivisions of a state; special purpose districts or public authorities with transportation functions (including port authorities); Tribal governments or consortia of Tribal governments; partnerships between Amtrak and one or more eligible public entities; and groups or coalitions made up of any of the eligible entity types. U.S. territories are explicitly eligible as well, which matters for major port, aviation-adjacent ground access, and freight projects in territorial jurisdictions.
From the source details provided, this is a discretionary grant (meaning awards are competitive rather than formula-based), offered as a grant funding instrument, administered by DOT (Agency code 69A345, Office of the Under Secretary for Policy). The opportunity number is NIPA 23 24 MEGA, it was created on June 26, 2023, and it listed an original closing date of August 21, 2023. DOT also points applicants to prior-year selections as a reference point, with FY22 award information available on the DOT MEGA grant program page, which can be useful for understanding the kinds of projects that have been competitive and the typical scope of funded work.Apply for NIPA 23 24 MEGA
