The Midpoint Assessment
The Infrastructure Investment and Jobs Act, signed into law in November 2021 with $550 billion in new federal spending above baseline levels, has reached its midpoint. According to the White House infrastructure implementation tracker and agency-level disbursement data, approximately $284 billion has been disbursed or formally committed to specific projects through March 2026.
That leaves roughly $266 billion still to flow over the remaining authorization period, which runs through fiscal year 2026 for most programs, with some extending to FY2028 and beyond for broadband and certain competitive grant categories.
The halfway mark is a useful moment to assess what has actually happened — which programs have moved money efficiently, which have lagged, where the construction work is concentrated, and what the second half of IIJA spending is likely to look like for contractors.
Where the Money Has Gone
The $284 billion in disbursed or committed funds breaks down roughly as follows across major program categories:
Highways: $110 Billion
The Federal Highway Administration programs account for the largest share, which is by design — highways received the biggest allocation in the law. The bulk of this money has flowed through formula programs to state DOTs, which have in turn let contracts through their normal procurement processes. Formula funds are the most predictable and fastest-moving category because they follow established distribution channels. States receive their apportioned share annually and have well-developed systems for programming and obligating those funds.
Transit: $47 Billion
Federal Transit Administration programs have disbursed approximately $47 billion, split between formula grants to transit agencies and competitive Capital Investment Grants for major new projects. Several large transit projects have received full funding grant agreements during this period, including extensions and new light rail lines in multiple metro areas.
Broadband: $35 Billion
The Broadband Equity, Access, and Deployment (BEAD) program and related initiatives have committed approximately $35 billion, though actual construction spending has lagged commitments significantly. NTIA allocated BEAD funds to states in 2023 and 2024, but states then had to develop plans, run their own competitive processes, and award subgrants to internet service providers. As of early 2026, most states are still in the subgrant award phase, and physical construction of broadband networks is only beginning to ramp in a handful of states.
Water Infrastructure: $32 Billion
EPA programs including the Drinking Water State Revolving Fund, Clean Water State Revolving Fund, and targeted lead service line replacement funding have moved approximately $32 billion. The lead service line replacement program has been particularly active, with the EPA estimating that over 300,000 lead lines have been replaced or are under contract nationally.
Bridges: $22 Billion
The Bridge Formula Program and competitive bridge grants have committed roughly $22 billion. The Federal Highway Administration reports that more than 7,800 bridge projects have received funding, ranging from small rural bridge replacements to major rehabilitation projects on Interstate structures. The backlog of structurally deficient bridges has declined from approximately 43,000 to an estimated 39,500 during this period.
Other Programs: $38 Billion
The remaining funds are spread across airports (FAA), ports and waterways (Army Corps of Engineers), electric vehicle charging infrastructure (FHWA/Joint Office), rail (FRA), resilience programs, and environmental remediation. These programs vary widely in their disbursement rates, with airport infrastructure moving relatively quickly and EV charging infrastructure proving more complex to deploy than originally anticipated.
State-Level Distribution
Total IIJA disbursements by state follow a predictable pattern: the largest states receive the most total dollars because formula allocation is based on factors like highway lane-miles, bridge count, transit ridership, and population.
The top five states by total IIJA funds received through early 2026:
- California: approximately $38 billion
- Texas: approximately $34 billion
- New York: approximately $26 billion
- Florida: approximately $19 billion
- Pennsylvania: approximately $17 billion
On a per capita basis, the picture looks different. Smaller states with large geographic areas and extensive highway networks receive disproportionately more:
- Alaska: approximately $5,800 per capita
- Wyoming: approximately $4,200 per capita
- Montana: approximately $3,600 per capita
- Vermont: approximately $3,400 per capita
- North Dakota: approximately $3,100 per capita
For contractors, the per capita data highlights where federal infrastructure spending has the greatest relative impact on local construction markets. In Alaska and Wyoming, IIJA funds represent a substantial share of total construction activity. In California and Texas, the absolute dollars are larger but represent a smaller share of their overall construction economies.
What Has Worked and What Has Lagged
Formula Programs: On Track
The highway and transit formula programs have performed largely as expected. State DOTs and transit agencies have established processes for receiving and spending federal funds, and the increased IIJA allocations have flowed into existing procurement pipelines. Highway construction activity has been robust, with FHWA reporting a 14% increase in the total value of highway contracts let since IIJA's passage compared to the prior four-year period.
Competitive Grants: Slower and More Complex
The competitive grant programs — RAISE grants, INFRA grants, Mega grants, Bridge Investment Program competitive grants — have moved more slowly. These programs require applications, review processes, negotiations, and environmental clearances that take 12 to 24 months before construction can begin. They also tend to fund larger, more complex projects with longer design and construction timelines.
For smaller contractors, competitive grants are also harder to access. The application process is resource-intensive, and many of the funded projects are large enough to require bonding capacity and experience levels that favor major contractors.
Broadband: Behind Schedule
The BEAD program is substantially behind the original timeline. The program's structure — federal funds to states, states develop plans, states award subgrants, subgrantees build networks — created a multi-year administrative process before any fiber gets buried. Industry groups estimate that peak BEAD-funded construction activity will not occur until 2027 or 2028, well behind initial projections.
For contractors with trenching, boring, and fiber installation capabilities, the broadband buildout represents a significant future opportunity, but patience is required. The work is coming, but it is arriving later and will ramp more gradually than many expected.
EV Charging: More Difficult Than Expected
The National Electric Vehicle Infrastructure (NEVI) program has struggled with supply chain issues, permitting complications, utility interconnection delays, and site acquisition challenges. Deployment of NEVI-funded chargers along Interstate corridors has been slower than the initial 2024 target. The construction scope per site is modest (typically site work, electrical service, and equipment installation), but the cumulative volume across thousands of planned sites represents meaningful work for electrical and site contractors.
What the Second Half Looks Like
The remaining $266 billion will not flow at a uniform rate. Several factors will shape the pace and distribution of second-half spending.
Acceleration in Highway and Bridge Spending
State DOTs are now fully in execution mode on their IIJA-enhanced programs. The initial year or two involved planning, design, and procurement setup. Construction activity on IIJA-funded highway and bridge projects will be at or near peak levels through 2027.
Broadband Ramp-Up
BEAD-funded broadband construction is expected to begin ramping significantly in late 2026 and peak in 2027-2028. This will create demand for directional drilling crews, fiber splicers, and related trades, particularly in rural areas.
Competitive Grant Project Construction
Many of the large competitive grant projects awarded in 2023 and 2024 are now moving through design and into construction. These projects will generate peak construction spending in 2026-2028.
Political and Administrative Variables
Federal infrastructure spending is always subject to political dynamics. Administration changes, congressional appropriations decisions, and agency staffing levels can accelerate or slow disbursement rates. The IIJA's funding is authorized and largely appropriated, which provides more certainty than annual discretionary programs, but implementation pace can still vary.
What Contractors Should Know
The Money Is Real and Flowing
Despite bureaucratic delays in some programs, $284 billion has moved from the federal treasury to projects on the ground. This is not theoretical funding — it represents actual construction contracts, actual jobs, and actual revenue for contractors.
Formula Funds Are the Easiest Entry Point
For contractors looking to capture IIJA-funded work, state DOT and transit agency procurements funded by formula programs are the most accessible. These follow established procurement rules, have predictable timelines, and include small contractor set-asides in most states.
Competitive Grants Favor the Prepared
Contractors who want to work on larger competitive grant-funded projects should track awards through the USDOT project dashboard and develop relationships with the project sponsors (typically state DOTs, transit agencies, or local governments) well before construction procurement begins.
DBE and Small Business Requirements
Most IIJA-funded projects carry Disadvantaged Business Enterprise goals, typically 10% to 15% of contract value. Some programs include specific small business set-asides. For qualifying firms, these requirements create protected market share on federal-aid projects.
Bonding Capacity Matters
Federal-aid construction projects require performance and payment bonds. Contractors should ensure their bonding capacity is sufficient to pursue the project sizes they are targeting. The surety industry has generally been supportive of capacity increases for qualified firms, but this requires advance planning.
The second half of IIJA spending will generate hundreds of billions of dollars in construction activity across highways, bridges, transit, water, broadband, and other infrastructure categories. The contractors who capture that work will be those who are tracking the pipeline, maintaining their qualifications, and positioning their capacity where the money is flowing.
