Federal transportation spending on bicycles and walking infrastructure amounts to just 1.5% of the total federal transportation budget. To put that in perspective: even though biking and walking account for 12% of all trips Americans take, these modes of transportation receive roughly one-eighth the funding they should relative to their use. The disparity becomes even starker when you compare bike funding directly to highway spending.
While billions flow annually into road construction, maintenance, and expansion, the dedicated programs for cycling infrastructure scrape by on comparatively pennies—a gap so wide it reflects a fundamental mismatch between how Americans actually move and where the government invests its transportation dollars. This isn’t a rounding error or a temporary shortfall. The Transportation Alternatives program, which is the primary federal funding source for bike lanes, trails, and pedestrian safety projects, receives only 2-3% of surface transportation funding under current law. That means a city hoping to build a protected bike network might spend months chasing a grant that would fund maybe five miles of lanes, while a single highway expansion project consumes ten times the budget with far less administrative burden.

Why Is Federal Bike Funding So Far Behind Highway Spending?
The disparity traces back to decades of federal transportation policy built around the automobile. When the Interstate Highway System was authorized in 1956, it fundamentally shaped how Washington allocated transportation money: highways got baseline funding as a national priority, while everything else—transit, cycling, walking—had to justify itself as an alternative or special interest. That hierarchy persists today. The Federal Highway Administration, the agency responsible for overseeing $40+ billion in annual transportation spending, was essentially created to build highways. Shifting even a small percentage of that funding to other modes requires Congress to explicitly reallocate money, which means taking it from highways. Politically, that’s a nonstarter in most states.
The funding mechanism itself favors highways. The federal gas tax, which fills the Highway Trust Fund, was last increased in 1993. That means it hasn’t kept pace with inflation or transportation needs for over 30 years. Meanwhile, bike and pedestrian programs depend on discretionary appropriations—funding that has to be fought for annually and is often the first target when budgets tighten. A city applying for federal highway money can count on a predictable stream of funding year after year. A cycling advocate applying for a bike lane grant might be competing against dozens of other cities for a limited pool, knowing that next year’s funding could be cut by half.
What Does 1.5% Actually Mean for Cycling Infrastructure?
At the ground level, this funding gap means most American cities can’t build the cycling infrastructure they want. A protected bike lane costs roughly $500,000 to $1 million per mile depending on local factors. If a city secures a federal grant for $2 million, that’s enough for two to four miles of protected bike lanes—in a metropolitan area covering hundreds of square miles. Compare that to a single highway interchange project, which frequently costs $50 million to $100 million but serves significantly fewer trips per dollar spent. One highway project could have funded fifty miles of cycling infrastructure.
The limitation becomes apparent in how slowly networks expand. Cities like Portland and Minneapolis that have made cycling a priority still have significant gaps in their networks—stretches where riders must navigate dangerous intersections or share space with traffic. Those gaps exist not because the cities don’t want the infrastructure but because they lack the federal funding to connect the pieces. Meanwhile, rural areas and lower-income neighborhoods are often excluded entirely from cycling investment because they lack the local funding match required for federal grants. A wealthy suburb might have the tax base to contribute 20% of a bike lane project and qualify for 80% federal funding. A lower-income neighborhood might lack the local resources to compete for the same grant, effectively pricing them out of cycling infrastructure investment.
The Transportation Alternatives Program Is the Dedicated Bike Funding Pipe
The Transportation Alternatives program is technically the primary federal mechanism for funding bike lanes, trails, pedestrian projects, and safe routes to schools. Established in 1991 and expanded through subsequent transportation reauthorization bills, it’s the closest thing the federal government has to a dedicated cycling funding program. But even this program is starved relative to need. At 2-3% of surface transportation funding, Transportation Alternatives money is distributed across all 50 states and thousands of eligible projects. The competition is fierce, and success rates are low.
The program operates as a competitive grant system, which means cities and states have to write applications, demonstrate local support, show how a project serves a documented need, and prove they have funding to match the federal contribution. For a well-resourced city with a professional planning staff, this is manageable. For smaller towns and rural areas, the application process alone is a barrier. A cash-strapped municipality might not have staff to spend weeks preparing a grant application for a project that might not be funded anyway. This administrative burden effectively ensures that cycling infrastructure investment is concentrated in places that already have resources, widening the equity gap.
September 30, 2026—When Federal Transportation Funding Runs Out
The entire federal transportation funding law expires on September 30, 2026. This reauthorization moment is when Congress decides whether funding for highways, transit, biking, and walking stays the same, increases, decreases, or disappears entirely. It’s also when politicians and advocacy groups get to fight for their priorities. In previous reauthorizations, bike and walking advocates have made modest gains—securing the Transportation Alternatives program, establishing safe routes to schools funding, and incorporating cycling into planning requirements. But those gains are always tenuous because they depend on political will.
In early 2026, House Transportation and Infrastructure Committee Chair Rep. Sam Graves (R-MO) made his position clear: “We’re not going to be spending money on bike paths or walking paths.” He called for a “traditional highway bill” focused on roads and bridges. This statement crystallized what many cycling advocates feared—that the next reauthorization could slash or eliminate dedicated funding for bicycling and walking infrastructure. Unlike highway funding, which has broad bipartisan support and powerful construction industry backing, cycling funding lacks that political firepower. A highway contractor contributes to campaigns and employs workers in every congressional district. Bike lane contractors are smaller and more diffuse.
Over 1,100 Organizations Signed a Joint Letter to Protect Bike Funding
The threat of funding cuts has galvanized an unusual coalition. More than 1,100 organizations—including major bicycle manufacturers like SRAM, Shimano, and Trek, plus retailers, health organizations, environmental groups, and local advocacy nonprofits—signed a joint letter warning Congress about potential cuts to federal bike lane, trail, and road safety funding. These aren’t fringe voices. SRAM and Shimano are among the world’s largest component manufacturers. Trek is one of the largest bike brands globally. They signed because they understand that federal bike infrastructure funding directly affects bike sales.
When cities build protected bike networks, more people ride bikes and buy bikes and gear. The coalition represents a rare moment of unity across the cycling industry. Manufacturers, retailers, and advocacy groups that sometimes compete or disagree on other issues came together with a single message: protected federal funding for cycling and pedestrian infrastructure is essential for the industry and for public health. But even this unified front faces an uphill battle. Industry voices have less political weight than highway construction interests, and a single powerful senator or representative opposed to bike funding can block progress. The letter signals that the fight for September’s reauthorization will be serious and contested.
What Actually Gets Cut When Bike Funding Shrinks?
When cycling funding is constrained, specific projects disappear. Safe routes to schools programs, which fund infrastructure improvements around public schools to enable kids to walk and bike safely, are often among the first cuts. These programs directly prevent child injuries and deaths—children hit by cars is the leading cause of unintentional injury death for kids ages 5-14. When the program is underfunded, schools in lower-income areas that can’t afford to construct sidewalks and crossings on their own fall behind. Multi-use trail projects also disappear. Trails provide recreation, transportation, health benefits, and property value increases—studies consistently show that homes near quality trails appreciate faster than comparable homes elsewhere. But a trail requires land acquisition, grading, paving, and maintenance.
A 10-mile regional trail might cost $3-5 million. Without federal funding, most regions can’t build it. The result is uneven geography: wealthy areas build trails, lower-income areas don’t. Bike lane projects in dense urban areas also suffer. Protected bike lanes that separate cyclists from traffic cost $500,000-plus per mile. Many cities can build 1-2 miles per year with grants. If funding is cut by half, that’s one protected lane instead of two—progress slows, and the network remains fragmented and incomplete.
The Equity Problem Nobody Talks About
The 1.5% funding figure masks an even deeper equity issue: cycling infrastructure investment is concentrated in places that are already wealthy and educated, while cycling is most essential in lower-income areas where car ownership is lower. In wealthy suburbs, families can afford cars. In dense urban neighborhoods and lower-income areas, more people depend on bikes and transit. Yet federal cycling funding often goes to communities that are already served by strong advocacy groups, professional planning departments, and local funding capacity. A wealthy college town might secure a federal grant for a trail because university planners know how to write the application. A lower-income neighborhood might have more people who actually need to bike but lack the institutional capacity to compete for federal money.
The federal funding structure also reinforces this disparity through matching requirements. Many grants require 20-30% local funding match. A wealthy city can easily cover the match with tax dollars or private donations. A lower-income municipality can’t. This effectively means that poor communities are priced out of federal cycling infrastructure investment, even though residents of those communities often depend most heavily on bicycles as primary transportation. The 1.5% figure, low as it is, understates the real inequity because it’s not evenly distributed—it’s concentrated where wealth and political power are highest.
