Too often, federal infrastructure policy prioritizes political goals over Americans’ needs and unnecessarily drives up costs. There are three common federal infrastructure policy problems that Congress should tackle in order to increase the value of America’s public infrastructure stock without increasing the national debt or hiking up taxes for hard-working families: (1) hidden cross-subsidies for low-demand infrastructure; (2) wasteful and unnecessary federal involvement in infrastructure projects; and (3) federal discouragement of state, local, and private-sector infrastructure activity. This Backgrounder presents solutions to these three problems.

Key Takeaways

Federal infrastructure policy should empower states to meet their populations’ unique needs, enhance the public good, and manage taxpayer dollars responsibly.

Too often, federal infrastructure involvement prioritizes political goals over Americans’ needs and unnecessarily drives up costs.

Uncertainty about post-pandemic travel and commuting gives Congress even more reason to limit federal control, curb spending, and reduce regulations.

At the start of the 116th Congress, there was a sense that the divided government would find few areas of agreement regarding legislation. One policy issue that typically enjoys overwhelming bipartisan support is transportation and infrastructure, but even that has succumbed to dysfunction in Congress.

Congress has so far been unable to pass legislation to reauthorize spending from the Highway Trust Fund and water development projects performed by the Army Corps of Engineers. While Congress could still act on water development after the election, the highway bill was given a one-year extension as part of September’s continuing resolution rather than a standard five-year reauthorization.REF

Although this increases the workload for the 117th Congress, it also provides an opportunity for those legislators to address the many dysfunctional aspects of federal infrastructure policy. There are ways to increase the value of America’s public infrastructure stock without increasing the national debt or hiking up taxes for hard-working families. Congress should tackle three common federal infrastructure policy problems to make this happen.

Problem 1: Hidden Cross-Subsidies for Low-Demand Infrastructure

Most federal infrastructure spending flows from the Highway Trust Fund, the Airports and Airways Trust Fund, and the Harbor Maintenance Trust Fund. Currently, each of these funds is governed by statutes that use tax revenue generated from high-demand infrastructure to subsidize low-demand infrastructure.

The federal fuel tax is the primary source of the Highway Trust Fund.REF In theory, this means that drivers are paying for the roads they use. However, roughly 28 percent of spending from the fund is diverted away from highways. The largest of these diversions goes toward urban transit systems, which do not pay into the fund. Other diversions include streetcars, bike paths, and walking paths, which also do not pay into the fund and should not be federal concerns. Over the past several decades, this has meant hundreds of billions of dollars in taxes on drivers to support non-driving infrastructure, even though the vast majority of U.S. travel takes place by car.REF

Several aviation taxes fuel the Airport and Airway Trust Fund, which in turn provides grant funding to airports for infrastructure activity. Statutory formulas dictate most of the grant provisions, and on a per-passenger basis, the grants heavily favor low-traffic airports. This amounts to a transfer from large to small airports, with many airports contributing relatively little to the trust fund while receiving a substantial portion of grants.REF

The Harbor Maintenance Trust Fund, which receives revenue from a tax on cargo ships, has a 10 percent set-aside for “emerging ports.”REF Although “emerging” typically implies growth, in this context, emerging ports simply means low traffic volume and guarantees a subsidy for small ports at the expense of busy ones.REF

The cross-subsidies and transfers are not primarily driven by policy considerations, but rather by political ones. Infrastructure needs are not evenly distributed between states and localities, yet legislation requires broad support to pass into law. As a result, small airports and harbors receive special treatment to win support from members whose districts lack large facilities, and urban members demand the transit set-aside since their constituents drive fewer miles than those in suburban and rural areas.REF

Such political calculations reduce the value of federal infrastructure spending. Rather than prioritizing funding for infrastructure of genuine national need that would not happen without federal involvement, current infrastructure programs are designed to fund the greatest number of discrete projects in the greatest number of locations. Since high-use infrastructure provides the greatest return on investment, this approach is exactly backwards.

Solutions. Congress should remove diversions and set-asides within these infrastructure trust funds. This would include eliminating funding for transit and “transportation alternatives” in the Highway Trust Fund and reforming funding from the Airport and Airway Trust Fund and Harbor Maintenance Trust Fund so that they no longer heavily subsidize small facilities. Such changes would improve the financial health of the trust funds, potentially enable tax cuts, enhance the economic value of spending, and remove arbitrary and unfair transfers between individuals based on the type and location of infrastructure they use.

Achieving these policies will require a concerted effort that brings public attention to the inefficiency and political manipulation inherent in current federal infrastructure programs. An example of this is the movement that led to the reduction and eventual ban on earmarks, which became synonymous with waste and corruption.REF

Problem 2: Wasteful and Unnecessary Federal Involvement in Infrastructure Projects

The most famous example of federal infrastructure is the Interstate highway system, which began with the Federal Aid Highway Act of 1956 and was completed in 1992. While the interstate system does provide significant benefits throughout the country, it is an anomaly when it comes to federal funding of infrastructure.

Most benefits from a typical infrastructure project go to people who live in the immediate area and use the infrastructure regularly. Accordingly, most infrastructure construction and operations are handled by state and local governments along with the private sector. It is rare for an infrastructure project to provide benefits to a wide enough area to necessitate federal involvement.REF

Yet, the federal government currently funds every sort of infrastructure imaginable, often for projects as localized as sidewalks. This leads to a variety of inefficiencies.

In some cases, federal funding is enough to make a dubious project possible. The cost of a federally funded project is distributed over a larger number of federal taxpayers, and thus attracts less scrutiny than one funded at the local level.REF

Federal funding is skewed toward initial construction over maintenance, which is typically covered by state and local governments. State and local officials have short-term incentives to seek federal funds for new projects, but this leads to rising maintenance costs over time.REF

Federal funding for a project triggers several costly regulatory mandates. These include the Davis–Bacon Act, which requires inflated union-rate wages; project labor agreements, which dictate union-style work rules; and Buy American rules, which increase the cost of raw materials.REF

Federal involvement prolongs completion for genuinely worthwhile projects. The process of applying for federal funds and obtaining necessary approvals can add months or even years to the completion date. A significant factor is the outdated and redundant National Environmental Policy Act, which adds costly roadblocks to the approval process even after reforms to streamline the process were implemented by the Trump Administration.REF

While transportation needs vary significantly between regions and localities, federal policy too often involves a one-size-fits-all approach. This includes mandating transit spending nationwide despite the limited use of transit outside New York City.REF Further, emerging trends, such as telecommuting, ride-sharing, and automated vehicles will change travel patterns in unpredictable and unevenly distributed ways. The federal government is less nimble and responsive to such changes than state and local governments or businesses, and thus should not have a primary role in infrastructure decisions.

Solutions. Congress should reduce federal infrastructure spending across the board and cut corresponding taxes on gas, aviation, and ports accordingly. This would empower non-federal actors that have better knowledge of local and regional needs. Congress should repeal the Davis–Bacon Act, Buy American rules, and the National Environmental Policy Act, which would reduce the cost of federally funded projects. The executive branch should repeal Executive Order 13502, issued by President Barack Obama, which mandates project labor agreements on federal projects.REF

Problem 3: Federal Discouragement of State, Local, and Private-Sector Infrastructure Activity

In addition to cross-subsidies and red tape arising from federal infrastructure spending, there are several federal policies that make it more difficult for businesses and state and local governments to raise and spend their own funds.

States are barred from tolling Interstate highways, aside from a handful of legacy roads that were built before 1956. This ban forces states to rely heavily on gas tax revenue, which is problematic as hybrid and electric vehicles comprise an increasing share of automobiles.REF The improving efficiency of electronic tolling means that tolls are much less expensive to implement than they were when the tolling ban was first imposed. Further, tolls are a better way to link the costs and benefits of a highway to its users, rather than gas tax increases that hit drivers regardless of their highway use.REF

The federal government subsidizes state and local infrastructure activity by making interest on qualifying municipal bonds tax-free, which lowers federal revenue by tens of billions of dollars per year.REF There is no limit on this subsidy. Tax-free interest is also available to private-sector surface transportation infrastructure activity through private activity bonds (PABs), which are capped at $15 billion in active bonds.REF The value of this tax subsidy is $100 million per year, a minuscule amount compared to municipal bonds.REF The structure of this lopsided federal subsidy makes infrastructure financing much more affordable for state and local governments than similar competing private-sector projects, serving to constrict private activity.

The federal government limits how airports can monetize their passengers in order to pay for infrastructure projects. Specifically, airports can only impose a Passenger Facility Charge (PFC) of up to $4.50 per person, which has been the case since 2000.REF Critics of the PFC refer to it as a “tax,” but it is in fact a user fee, which is the ideal way to pay for infrastructure. Further, airports face market pressures on pricing, such as competition with other modes of transportation (including nearby airports), meaning there would be natural limits on facility charges without the arbitrary federal cap. The $4.50 limit makes it harder for airports to properly finance activities, such as expansion and modernization, and serves to make airports dependent on federal subsidies from the Airport and Airway Trust Fund.

Solutions. Congress should lift the ban on states tolling Interstate highways, which would reduce state government reliance on Washington and on gas taxes. Congress should level the playing field between municipal bonds and PABs, which would most likely mean increasing or eliminating the $15 billion limit on PABs.REF Finally, Congress should remove the PFC limit, which would enable airports to expand and modernize in years to come. This should be coupled with a reduction in federal aviation taxes and spending.


While it might seem to some that the easiest way for the federal government to enhance the nation’s transportation infrastructure is through an increase in spending and subsidies, the opposite is the best path forward. Many current rules and programs are badly outdated, or serve primarily to enhance political goals rather than the public good, creating tremendous cost and inefficiency. Reducing federal spending and regulation would create space for the private sector, and state and local governments, to increase the quality and capacity of transportation infrastructure that Americans need most.
