WASHINGTON — With the looming expiration of the landmark 2021 surface transportation law, Capitol Hill is facing a pivotal legislative test. Lawmakers, policy experts, and industry stakeholders are engaged in tense negotiations to craft a new multi-year surface transportation reauthorization bill before federal funding authority lapses at the end of the fiscal year.
The political and legislative complexities of this high-stakes battle were analyzed on CQ Roll Call’s Political Theater podcast. Editor-in-Chief Jason Dick, staff writer Kelly Livingston, and 535 political analyst Susan Davis broke down the state of play on Capitol Hill, highlighting the sharp policy divides, revenue shortfalls, and procedural hurdles facing the bipartisan coalition needed to pass the massive infrastructure package.
Main Facts: The Race Against the Fiscal Clock
The centerpiece of federal infrastructure policy—the five-year surface transportation authorization enacted under the Infrastructure Investment and Jobs Act (IIJA) of 2021—is scheduled to expire on September 30, 2026. Without Congressional action, the federal government’s legal authority to obligate funds for highways, public transit systems, passenger rail, and road safety programs will end, freezing billions of dollars in federal aid to states and local municipalities.
Key elements of the ongoing debate in Congress include:
- Scope and Scale: The upcoming reauthorization is expected to top $600 billion over five years, addressing formula grants to states, discretionary grant programs, bridge replacements, public transportation modernization, and highway safety initiatives.
- The Revenue Deficit: The Highway Trust Fund (HTF), the primary funding vessel for federal highway and transit spending, faces structural insolvency. Revenue from the federal motor fuels tax remains insufficient to cover projected outlays, forcing lawmakers to decide between alternative user fees, direct general fund transfers, or tax adjustments.
- Policy Friction: Significant ideological splits have emerged between House Republicans and Senate Democrats over funding allocations. Key friction points include electric vehicle (EV) charging networks, climate resilience mandates, transit vs. highway spending ratios, and environmental review processes under the National Environmental Policy Act (NEPA).
- Legislative Timetable: With lawmakers away for the August recess and a crowded autumn calendar, the window for passing a comprehensive, multi-year bill before October 1 is narrow. Analysts note that a temporary, short-term extension may be required to keep federal funds flowing while negotiations continue.
During the Political Theater discussion, CQ Roll Call’s panel emphasized that while surface transportation bills historically enjoy a degree of cross-party cooperation, the broader fiscal environment and stark ideological differences over federal spending make the 2026 reauthorization particularly contentious.

+-------------------------------------------------------------------+Chronology: The Path to the 2026 Infrastructure Deadline
The path to the current reauthorization debate spans five years of implementation, shifting macroeconomic conditions, and changing political dynamics in Washington.
1. November 2021: Enactment of the IIJA
President Joe Biden signed the Infrastructure Investment and Jobs Act (Public Law 117-58) into law after months of negotiations. The $1.2 trillion statute included $550 billion in new federal spending over five fiscal years (FY 2022–2026), marking the largest federal investment in public transit, passenger rail, and bridge infrastructure in decades.
2. 2022–2024: Rollout, Inflation, and Implementation
As the U.S. Department of Transportation (USDOT) rolled out thousands of formula grant allocations and discretionary awards, unexpected macroeconomic headwinds emerged. High post-pandemic inflation substantially elevated construction costs, raw material prices (such as steel, asphalt, and concrete), and labor rates. Consequently, state departments of transportation (DOTs) saw a portion of their increased federal funding offset by reduced purchasing power.
3. Late 2025: Committee Preparation Begins
The House Committee on Transportation and Infrastructure (T&I) and the Senate Committee on Environment and Public Works (EPW), along with the Senate Banking and Commerce committees, initiated listening sessions and field hearings. Industry groups and state officials urged lawmakers to begin drafting the next surface bill early to avoid mid-decade planning interruptions.
4. Spring 2026: Draft Proposals and Partisan Split
In early 2026, committee leaders published competing draft framework proposals. House leaders favored a streamlined bill prioritizing traditional highway paving, rural bridge repair, and regulatory reform, while calling for cuts to dedicated EV infrastructure programs. Senate leaders maintained that any multi-year bill must preserve dedicated funding for carbon-reduction initiatives, transit expansion, and climate resiliency.
5. August 2026: Recess Deadlock and Reauthorization Summit
As Congress adjourned for its summer recess, leadership had yet to bridge the gap on funding mechanisms or policy riders. On the Political Theater podcast, Roll Call journalists noted that while behind-the-scenes staff negotiations continue through late August, the prospect of a frantic September sprint—or a series of short-term extensions—remains high.
Supporting Data: Funding Gaps and Highway Trust Fund Mechanics
The policy struggle over the surface transportation bill is driven by structural financial challenges within federal infrastructure finance.
The Highway Trust Fund Insolvency
The Highway Trust Fund relies primarily on federal excise taxes on gasoline (18.4 cents per gallon) and diesel fuel (24.4 cents per gallon). These rates have remained fixed without adjustments for inflation since 1993.
Gasoline Tax Rate (Fixed since 1993) : 18.4¢ per gallon
Diesel Tax Rate (Fixed since 1993) : 24.4¢ per gallon
Estimated Annual HTF Deficit : $25B - $35B annually
Cumulative General Fund Transfers : > $275B since 2008Because modern vehicles are increasingly fuel-efficient and electric vehicles pay no motor fuel taxes, receipts entering the HTF have consistently fallen short of outlays authorized by Congress. To cover this gap, Congress transferred more than $275 billion from the General Fund of the Treasury into the Highway Trust Fund between 2008 and 2021.
Purchasing Power Deterioration
Data from the National Highway Construction Cost Index (NHCCI) reveals that highway construction costs rose by more than 50% between 2021 and 2025. As a result, states face significantly higher per-mile costs for routine road maintenance, paving, and bridge repairs than when the IIJA was enacted.
+-----------------------------------------------------------------------+
| HISTORICAL HIGHWAY TRUST FUND BALANCES & OUTLAYS |
+-----------------------------------------------------------------------+
| Fiscal Year | Excise Revenue | Authorized Outlays | General Transfer|
+---------------+----------------+--------------------+-----------------+
| 2022 | $48.2 Billion | $68.5 Billion | IIJA Offset |
| 2023 | $47.8 Billion | $72.1 Billion | IIJA Offset |
| 2024 | $47.1 Billion | $75.8 Billion | IIJA Offset |
| 2025 | $46.5 Billion | $78.4 Billion | IIJA Offset |
| 2026 (Est.) | $45.9 Billion | $81.2 Billion | IIJA Expiration |
+-----------------------------------------------------------------------+State Reliance on Federal Funding
Federal funds account for an average of 45% to 50% of state DOT capital outlays for highway and bridge projects, with several rural states relying on federal money for over 70% of their capital construction budgets. Any interruption or delay in federal authorization immediately affects long-term project planning and state contracting schedules.
Official Responses and Stakeholder Perspectives
The debate over the surface transportation reauthorization features a wide range of positions from key lawmakers, executive agencies, and transportation advocacy groups.
Congressional Leadership and Committee Chairs
-
House Transportation and Infrastructure Committee Leadership:
Republican leadership on the House T&I Committee has emphasized spending efficiency, speed of project delivery, and core infrastructure needs."American taxpayers expect their infrastructure dollars to go directly into pavement and concrete, not endless administrative reviews or subsidized programs that do not rebuild our core freight networks," stated House committee leaders during recent hearings. "Our priority for this reauthorization is cutting red tape, streamlining NEPA approvals, and focusing funding on critical roads and bridges."
-
Senate Environment and Public Works Committee Leadership:
Senate EPW leadership maintains that climate resilience and modern transportation networks must remain integrated."We cannot retreat on climate action or modern mobility," Senate leaders countered during joint discussions. "The extreme weather events of recent years demonstrate that building resilient infrastructure isn’t optional—it is essential to economic stability. A modern reauthorization must invest in transit, passenger rail, and zero-emission transit options alongside traditional highway upgrades."
Executive Branch and USDOT
Officials at the U.S. Department of Transportation have called on Congress to avoid multi-year uncertainty and maintain momentum on major capital projects. Transportation leadership emphasized that state DOTs require predictable, long-term funding streams rather than temporary patches to execute complex, multi-year mega-projects.
Industry and Labor Stakeholders
-
American Association of State Highway and Transportation Officials (AASHTO):
AASHTO leadership has warned against relying on short-term funding extensions (Continuing Resolutions), which can disrupt project scheduling."State DOTs operate on multi-year planning horizons. When federal funding is delivered through short-term patches, state agencies cannot comfortably enter into long-term construction contracts. We strongly urge Congress to pass a robust, multi-year bill prior to September 30."
-
American Road & Transportation Builders Association (ARTBA):
ARTBA focused on addressing the erosion of the Highway Trust Fund and purchasing power challenges."Inflation has eroded a substantial portion of the gains from the 2021 bill. Congress must secure a permanent, dedicated revenue model for the Highway Trust Fund that ensures all road users—including electric vehicle drivers—contribute equitably to network maintenance."
-
American Public Transportation Association (APTA):
APTA pushed back against proposals to alter the historical 80/20 funding split between highways and mass transit."Public transportation systems across the country are facing operational budget gaps and essential capital replacement backlogs. Reducing the proportion of transit funding in this reauthorization would undermine urban mobility, exacerbate traffic congestion, and hit working families hardest."
Policy Implications and Strategic Outlook
As the September 30 deadline approaches, lawmakers face critical structural choices that will shape federal transportation policy for the rest of the decade.
1. The Solvency Dilemma: Finding New Revenue Streams
Congress must resolve how to fund the gap between highway excise tax receipts and projected spending. Options under consideration include:
- EV Registration Surcharges: Implementing an annual federal registration fee or kWh charging fee for electric vehicles to balance user-fee contributions.
- Vehicle Miles Traveled (VMT) Fee: Expanding pilot programs for a nacional mileage-based user fee system, though administrative complexity and privacy concerns present obstacles to full implementation.
- General Fund Transfers: Continuing direct transfers from general revenues, which increases the federal deficit but avoids tax rate adjustments.
2. Regulatory Reform vs. Environmental Oversight
The balance between environmental review and construction timelines remains a core policy division. Conservative proposals favor strict time limits on environmental impact statements and judicial review, arguing that delays add costs to public projects. Progressive proposals emphasize environmental justice assessments and public comment periods, maintaining that thorough reviews protect vulnerable communities and prevent long-term environmental damage.
3. State Budget Stability and Mega-Project Planning
Failure to enact a long-term reauthorization bill before October 1 could disrupt construction schedules across the country. If Congress relies on a series of short-term extensions, state DOTs may delay advertising new project bids, deferring major bridge overhauls, interstate expansions, and transit corridor modernizations.
4. Macroeconomic and Workforce Impacts
The transportation construction sector remains a key source of high-wage jobs in civil engineering, manufacturing, and trade labor. Policy shifts or funding shortfalls in the reauthorization bill could directly affect hiring schedules, supply chain infrastructure investments, and regional economic performance.
Legislative Next Steps
With limited legislative days remaining before the end of the fiscal year, pressure is building on House and Senate leadership to finalize a bi-cameral compromise. As analyzed on CQ Roll Call’s Political Theater podcast, the coming weeks will reveal whether Congress can forge a bipartisan path forward on surface transportation, or if Capitol Hill will be forced to rely on a temporary stopgap measures as the September 30 deadline arrives.
