President Trump’s administration is proposing substantial cuts to federal transit funding through its FY2027 budget proposal, which would slash public transit funding to $16.3 billion—a 23% decrease from the previous year—while cutting passenger rail funding to $2.8 billion, an 82% reduction. Beyond budget proposals, the administration has already taken concrete action: the White House held up a $16 billion transportation project in New York in February 2026, and the Department of Transportation has clawed back, threatened, or delayed funding for transit grants authorized under the Biden administration. These cuts represent a fundamental shift in federal transportation priorities away from public transit and rail infrastructure toward highway investment.
The most significant structural change involves the proposal to eliminate the mass transit account of the Highway Trust Fund, which historically reserves approximately 20% of gas tax revenues—money that currently flows directly to transit agencies across the country. Additionally, the administration has implemented a freeze on new Capital Investment Grants, meaning no new subways, elevated rails, monorails, or automated light metro systems have been authorized since Trump took office. This combination of budget cuts, funding freezes, and structural elimination of dedicated transit revenue sources creates an unprecedented challenge for cities and transit agencies nationwide.

HOW MUCH FEDERAL TRANSIT FUNDING IS BEING CUT?
The numbers tell a stark story about the scope of proposed reductions. The FY2027 budget proposal cuts public transit funding to $16.3 billion, representing a 23% decrease from the previous fiscal year. For context, this reduction eliminates resources that would have supported bus systems, commuter rail, light rail, and subway operations across hundreds of American cities.
The cuts to passenger rail are even more severe: the proposal reduces rail funding to $2.8 billion, an 82% reduction that would devastate intercity rail service and rail infrastructure modernization projects. These percentage decreases translate into billions of dollars in lost federal support. For example, a mid-sized metropolitan area that received $100 million in federal transit grants under the previous budget would face a cut of approximately $23 million under the proposed FY2027 budget. Smaller cities and rural transit agencies, which often depend more heavily on federal matching funds, face even steeper relative impacts. The combination of transit and rail cuts means that the federal government would be withdrawing over $10 billion in annual support from the transportation systems that move millions of Americans to work, school, and medical appointments.
THE CAPITAL INVESTMENT GRANT FREEZE AND NEW PROJECT AUTHORIZATION
Beyond budget line items, the trump administration has implemented a de facto freeze on new transit projects through its control over the Capital Investment Grant program, which is the primary federal mechanism for funding major public transportation infrastructure. Since Trump took office, no new subways, elevated rails, monorails, or automated light metro systems have been authorized under this program. This freeze blocks funding for projects that have been in planning or pre-construction phases, even those that had secured preliminary federal commitments or passed required environmental reviews.
The practical impact of this freeze is severe for cities with approved or near-approved projects. Transit agencies that spent years—sometimes a decade or more—developing environmental impact studies, securing local funding commitments, and navigating federal approval processes now face indefinite delays. A limitation of the Capital Investment Grant program is that it typically funds only a portion of large projects (usually 50%), requiring local and state governments to cover the remainder. When federal authorization stops, local partners face impossible choices: delay projects indefinitely, seek alternative funding sources, or abandon projects entirely. Cities like Los Angeles, Seattle, and Minneapolis have transit expansion plans that depend on federal grant authority that may not materialize under the current freeze.
THE MASS TRANSIT ACCOUNT ELIMINATION AND GAS TAX REVENUE
The proposal to eliminate the mass transit account of the Highway Trust Fund targets a fundamental source of dedicated transit revenue. Currently, approximately 20% of federal gas tax revenues are set aside for transit agencies through the mass transit account. This mechanism has been in place for decades and ensures that as Americans purchase gasoline, a portion of their gas tax goes to funding the public transportation systems in their communities. Eliminating this account would redirect that revenue exclusively to highway construction and maintenance.
The elimination proposal reveals a significant policy shift: it explicitly deprioritizes public transportation in favor of road infrastructure. If enacted, this change would strip away roughly $3 to $4 billion annually in dedicated transit funding—money that currently flows to transit agencies regardless of other budget pressures. The warning here is that state and local governments cannot simply replace this federal revenue. Most states lack the bonding capacity or political will to impose new dedicated revenue sources for transit, meaning that a permanent loss of gas tax-funded transit money would likely result in service cuts, deferred maintenance, and canceled expansion projects. Unlike general federal appropriations that can theoretically increase or decrease annually, the elimination of a dedicated revenue stream is typically permanent once enacted.
REAL-WORLD IMPACTS ON MAJOR TRANSIT PROJECTS
The $16 billion transportation project in New York that the White House held up in February 2026 exemplifies how the administration’s transit policies translate into consequences for specific infrastructure. This project, though initially funded through previous appropriations, required ongoing federal coordination and support. The hold-up demonstrated the administration’s willingness to use its administrative authority to restrict transit funding even before formal budget proposals take effect. This action sent a clear message to other cities and transit agencies: federal support for transit projects, even those previously approved, cannot be assumed under the current administration.
Beyond New York, the Department of Transportation has clawed back, threatened, or delayed funding for numerous transit grants that were authorized under the Biden administration. This creates uncertainty for projects in their planning or early construction phases. For example, transit agencies implementing new bus rapid transit systems or rail extensions face unpredictable federal funding timelines, making it difficult to lock in construction contracts or maintain worker scheduling. The comparison is instructive: during previous administrations, once a federal transit grant was awarded, the funding process followed a relatively predictable timeline. Under the current policy approach, even awarded funds may face threats or delays, requiring agencies to maintain contingency plans and potentially tap into local reserves to maintain project momentum.
THE EXPIRATION OF THE INFRASTRUCTURE INVESTMENT AND JOBS ACT
A critical deadline looms that will determine the long-term trajectory of federal transit funding: the Infrastructure Investment and Jobs Act (IIJA), commonly known as the Bipartisan Infrastructure Law, is expected to expire in September 2026. When the IIJA expires, Congress will be forced to write the next major federal transportation bill—and the Trump administration will have significant influence over its shape. Given the administration’s stated position on transit funding, there is a substantial risk that the new transportation bill will permanently codify lower transit funding levels and restructure the relationship between highways and transit in federal transportation policy.
The limitation and warning here cannot be overstated: the window for Congress to act before IIJA expires provides an opportunity to reset transit funding policy, but it also creates a critical decision point. If Congress does not act by September 2026 to reauthorize transportation spending with adequate transit funding, federal transportation appropriations could default to lower levels. Transit agencies should begin now preparing budget scenarios that assume federal transit funding could be further reduced after the IIJA expires. Cities and states that depend on federal transit grants should be mobilizing their congressional delegations and stakeholder communities to advocate for robust transit funding in the next transportation bill.
STATE AND LOCAL GOVERNMENT RESPONSES
States and local governments are responding to the threat of reduced federal transit funding in several ways. Some, like California and New York, are exploring state-level dedicated revenue sources for transit—typically sales tax increases or vehicle registration fee adjustments—to backfill lost federal dollars. However, this response has significant limitations. First, not all states have the political capacity to pass new taxes. Second, state revenues cannot fully replace federal funding, particularly in smaller metros and rural areas.
Third, the time required to pass legislation and implement new revenue sources means that gaps will exist between when federal funds are cut and when state funds become available. Other states are making difficult choices about which transit projects to prioritize and which to defer. For example, a state with three proposed light rail expansions might be forced to choose one and abandon the others if federal funding is unavailable. This creates winners and losers among communities within the same state, based not on project merit but on resource constraints. The practical tradeoff is clear: without federal funding support, transit expansion and modernization will slow significantly, while federal highways continue to receive substantial investment.
LOOKING AHEAD AT FEDERAL TRANSPORTATION PRIORITIES
The Trump administration’s transit funding proposals must be understood within the context of broader federal transportation priorities. The administration has signaled strong support for highway infrastructure, border wall construction, and projects that it deems priorities for economic development or national security. This represents a deliberate shift away from the previous administration’s emphasis on climate-related transit investments and urban mobility.
The question now facing Congress is whether it will endorse this reordering of federal transportation priorities or seek a different balance. Forward-looking, the next major federal transportation bill—expected to be debated and passed before or around September 2026—will be the vehicle through which these policy changes either become permanent or are modified. Transit advocates, environmental organizations, city and state governments, and labor unions representing transit workers are likely to mount significant campaigns to preserve federal transit funding. However, the administration’s stated commitment to reducing federal spending and its ideological preference for highway investment suggest that transit funding levels may remain depressed even if Congress provides some restoration from the most severe proposed cuts.
Conclusion
President Trump’s transit funding proposals and current policy actions represent a significant reduction in federal support for public transportation and rail infrastructure. The combination of proposed budget cuts—a 23% reduction in transit funding and an 82% reduction in rail funding—the freeze on new Capital Investment Grants, and the proposal to eliminate the mass transit account of the Highway Trust Fund would fundamentally reshape federal transportation policy. When added to immediate actions like the hold-up of the $16 billion New York project and clawbacks of previously authorized grants, it is clear that the administration is committed to reducing federal transit investment regardless of the budget outcome.
For transit agencies, cities, states, and travelers who depend on public transportation, the critical period is now through September 2026, when Congress will have the opportunity to reauthorize federal transportation funding through the next major transportation bill. The outcome of that legislative process will determine whether federal transit funding experiences a temporary reduction (which could be restored in subsequent appropriations) or a permanent restructuring that prioritizes highways over transit. Tracking the current budget proposals, monitoring federal funding actions, and understanding local impacts will be essential for anyone interested in how federal transportation policy affects their community’s mobility and economic development.
