The Infrastructure Investment and Jobs Act is not a future promise. It is active law with active money flowing through active contracts right now. As of early 2026, $312 billion of the $550 billion in new federal spending has been disbursed to states, municipalities, and federal agencies — and construction firms of every size are collecting it.
I have spent the last four years tracking IIJA funding flows, and the pattern is clear: the contractors who understand how the money moves are winning work. The ones waiting for projects to "show up" on their usual bid boards are missing billions in opportunities that flow through channels they have never monitored.
This guide breaks down every major IIJA funding category, shows you exactly where to find contracts, and identifies the project types where small and mid-size contractors have the best shot at winning.
Where the IIJA Money Stands in 2026
The numbers first. The IIJA authorized $1.2 trillion in total infrastructure spending over five years. That headline number includes two components that contractors need to understand separately.
The first is $550 billion in genuinely new spending — money that would not have existed without the bill. This is the portion that created new programs, expanded existing ones, and opened up project categories that were previously unfunded or underfunded. As of April 2026, approximately $312 billion of this new spending has been disbursed to recipient agencies and programs.
The second component is roughly $650 billion in baseline reauthorization — funding that extends existing transportation and infrastructure programs that Congress renews periodically. This money matters too, but it was largely expected by the industry. The new spending is what changed the game.
Here is the critical timeline context: IIJA was signed in November 2021 with most formula funding authorized through federal fiscal year 2026 and discretionary grant programs extending through 2028. We are now in the peak spending window. FY2025 and FY2026 represent the highest annual obligation rates for most major programs. If you are not pursuing this work now, you are sitting out the peak.
The $238 billion in new spending that has not yet been disbursed is not at risk. It has been appropriated by Congress. No additional legislative action is needed to release it. The only question is how fast agencies can process applications, make awards, and execute contracts — and that pace has been accelerating every quarter.
The 5 Biggest Funding Categories
Not all $550 billion in new spending is construction work. Some funds research, workforce development, and planning. But the construction-heavy categories are enormous.
1. Roads and Bridges — $110 Billion
The Federal Highway Administration received the largest single allocation: $110 billion split between formula funding distributed to every state DOT and competitive discretionary grants like the Bridge Investment Program and INFRA grants.
The bridge numbers alone justify attention. The United States has 42,966 structurally deficient bridges according to FHWA's National Bridge Inventory. The IIJA's Bridge Formula Program allocated $27.5 billion specifically for bridge repair and replacement — the single largest dedicated bridge investment in American history. Every state DOT has increased its bridge program in response.
Road work under IIJA goes beyond resurfacing. The law funds complete street reconstructions, highway capacity projects, wildlife crossings, and resilience improvements (raising roads above flood levels, reinforcing coastal highways). The National Highway Performance Program alone received $148 billion over five years in combined new and baseline funding.
2. Public Transit — $89.9 Billion
The Federal Transit Administration's $89.9 billion funds bus rapid transit systems, light rail extensions, subway station modernization, and fleet electrification. Major construction projects include the Gateway Program tunnel between New York and New Jersey ($12.3 billion federal share), Los Angeles Metro's Purple Line extension, and dozens of bus rapid transit corridors in mid-size cities.
For contractors, transit work means station construction, tunnel boring support, utility relocation, platform rehabilitation, and systems installation. The FTA's Capital Investment Grant program has a pipeline of 40+ projects in various stages of approval, most entering construction between 2025 and 2028.
3. Water Infrastructure — $55 Billion
The EPA received $55 billion for water infrastructure — the largest water investment since the Clean Water Act. This breaks into three main buckets.
Lead pipe replacement received $15 billion on its own. The EPA's revised Lead and Copper Rule requires water utilities to replace all lead service lines within ten years. That means millions of individual pipe replacements — small-diameter plumbing work, street cuts, service connections. This is not mega-project work. It is high-volume, distributed construction spread across thousands of municipalities.
Drinking water system upgrades received $11.7 billion through the Drinking Water State Revolving Fund. Wastewater and stormwater infrastructure received $12.7 billion through the Clean Water State Revolving Fund. The remaining funds cover emerging contaminants (PFAS treatment), water recycling, and dam safety.
4. Broadband — $65 Billion
Broadband might not sound like construction work, but $42.5 billion of the broadband allocation flows through the BEAD (Broadband Equity, Access, and Deployment) program — and every dollar of it requires physical construction. Someone has to trench the conduit, pull the fiber, set the poles, build the huts, and install the electronics.
States completed their broadband planning phase in 2024-2025 and are now entering the construction phase. This means RFPs for fiber installation are hitting state broadband office portals right now. The construction is predominantly underground utility work (directional boring, trenching, vault installation) and aerial construction (pole attachment, strand installation, fiber lashing).
5. Electric Grid and Clean Energy — $65 Billion
The Department of Energy received $65 billion for grid modernization, transmission line construction, clean energy demonstrations, and EV charging infrastructure.
The EV charging station construction program alone has $7.5 billion in funding. The National Electric Vehicle Infrastructure (NEVI) formula program is building charging stations along designated Alternative Fuel Corridors in all 50 states. Each station requires electrical work, concrete pads, canopy construction, and utility connections — projects typically ranging from $100,000 to $500,000 per site.
Transmission line construction under the Grid Resilience and Innovation Partnerships (GRIP) program has awarded $10.5 billion across three rounds of funding. These are major infrastructure projects — steel tower erection, conductor stringing, substation construction — with individual project values from $50 million to over $1 billion.
How to Find IIJA-Funded Contracts
This is where most contractors lose the thread. IIJA money does not all flow through a single portal. It fragments across federal agencies, state DOTs, municipal water utilities, state broadband offices, and dozens of other intermediaries. Here is the map.
Federal direct contracts appear on SAM.gov. Filter by NAICS codes in the 23xxxx series (construction) and look for funding references to IIJA, BIL (Bipartisan Infrastructure Law — the bill's other name), or specific program names like BFPP, NEVI, or BEAD. The Buildermuse bids page aggregates active federal construction solicitations from SAM.gov and makes them searchable.
State DOT pass-through is the biggest channel for roads and bridges. FHWA distributes formula funds to state DOTs, which then let their own contracts through their state procurement portals. Every state DOT has a letting schedule published months in advance. If you are not checking your state DOT's upcoming lettings page monthly, you are missing the majority of highway and bridge work funded by IIJA.
Municipal water and wastewater projects funded through the State Revolving Fund loans appear on local agency bid boards. The chain is: EPA sends money to state environmental agencies, which loan it to cities and counties, which then bid the construction work locally. Check your state's SRF program website for a list of funded projects — then monitor the corresponding municipal procurement sites.
Broadband BEAD projects flow through state broadband offices. The National Telecommunications and Information Administration (NTIA) allocated BEAD funds to each state, which created broadband offices to manage the program. Those offices are now releasing construction RFPs. Find your state broadband office at BroadbandUSA.gov.
Energy and grid projects come through DOE grant recipients, which are typically utilities, cooperatives, or state energy offices. These entities then subcontract the construction. Monitor the DOE's Grid Deployment Office announcements and your local utility's procurement pages.
State-by-State: Where the Most Money Is Going
IIJA funding is not distributed equally. Formula allocations follow existing federal formulas (highway lane-miles, bridge conditions, transit ridership, water system needs), and discretionary grants go to the states and projects that submit the strongest applications.
The top five states by total IIJA formula allocation over five years:
- California: $44.6 billion — largest total allocation, with massive transit, highway, and water projects. The largest per-project average in the country due to the state's preference for mega-projects.
- Texas: $35.4 billion — largest highway allocation of any state, driven by lane-miles and population growth. Heavy emphasis on rural broadband.
- New York: $26.9 billion — dominated by the Gateway Program and MTA capital work. Transit allocation alone exceeds most states' total IIJA share.
- Florida: $19.1 billion — highway resilience (flood-proofing I-75, raising coastal roads) and water infrastructure dominate.
- Pennsylvania: $17.8 billion — the highest per-capita allocation for bridge work in the nation, reflecting its 3,353 structurally deficient bridges (most of any state).

What Small Contractors Should Target
The headline IIJA projects — $12 billion tunnels, $4 billion highway widenings — grab attention but exclude 95% of contractors. The real opportunity for small and mid-size firms is in the thousands of projects under $5 million that collectively represent hundreds of billions in spending.
Lead pipe replacement is the single best opportunity for small plumbing contractors. Cities are hiring contractors for $50,000 to $500,000 jobs replacing lead service lines — individual residential connections from the water main to the house. Chicago alone needs to replace 400,000 lead lines. Newark, Milwaukee, Pittsburgh, and dozens of other cities have active programs. The work is repetitive, manageable, and the demand will persist for years.
Sidewalk and ADA compliance projects are flowing from FHWA's Transportation Alternatives Program. Municipalities are spending $1 million to $5 million per project on curb ramp installations, sidewalk replacement, and pedestrian infrastructure. These are concrete and site work contracts perfectly sized for local contractors.
Bridge preservation — not replacement — is a massive subcategory. Deck overlays, joint replacements, bearing replacements, rail upgrades, and scour countermeasures are all $500,000 to $2 million projects that state DOTs bid regularly. You do not need to build a whole bridge. You need to keep existing bridges from deteriorating further.
EV charging station installation runs $100,000 to $500,000 per site. The work is electrical (service upgrades, charger installation, panel work) plus civil (concrete pads, canopy foundations, striping). Electrical contractors with commercial experience can pursue these directly.
Rural water system upgrades funded through the Drinking Water SRF are often awarded to local and regional contractors because the projects are in areas that national firms find uneconomical to mobilize for. A $1.5 million water treatment plant upgrade in a town of 3,000 people is not attractive to a firm with $200 million in revenue — but it is a solid project for a contractor doing $5 million to $15 million annually.
Bonding and Capacity for Infrastructure Work
Federal construction contracts over $150,000 require performance and payment bonds under the Miller Act. State and local projects funded with federal dollars typically impose the same requirement. If you cannot get bonded, you cannot bid.
The Small Business Administration's Surety Bond Guarantee Program helps contractors who cannot obtain bonds through standard channels. The SBA guarantees bonds for contracts up to $10 million ($20 million for some federal contracts), reducing the surety's risk and making it easier for small firms to qualify.
Building bonding capacity is a deliberate process. Start with projects in the $1 million to $3 million range. Complete them on time and on budget. Your surety evaluates your track record, financial statements, and work-in-progress capacity. As your history grows, your single-project and aggregate bonding limits increase. Most contractors can grow from $3 million to $10 million in bonding capacity within two to three years of consistent performance.
Many state DOTs operate Mentor-Protege programs specifically designed to help small, disadvantaged, and emerging contractors build capacity on infrastructure projects. Larger firms sponsor smaller firms, providing project management support, equipment access, and subcontracting opportunities on set-aside work. These programs are underused. If you qualify as a DBE (Disadvantaged Business Enterprise), SBE (Small Business Enterprise), or similar designation in your state, the Mentor-Protege path is one of the fastest ways to build an infrastructure resume.
The Buy America Requirements
IIJA significantly strengthened Buy America provisions. All iron, steel, manufactured products, and construction materials used on federally funded infrastructure projects must be produced in the United States. This is not new for highway work (Buy America has applied to FHWA projects for decades), but the IIJA extended it to programs that previously had no domestic sourcing requirement — including water infrastructure, broadband, and energy projects.
The practical impact on contractors is real. You must verify material sourcing early in the project lifecycle — ideally during estimating and procurement, not after you have committed to a supplier. Submitting a mill certificate showing foreign-origin steel at the shop drawing review stage will result in rejection, rework, and delay.
The waiver process exists but is getting stricter. The Build America, Buy America Act allows federal agencies to grant waivers when domestic products are not available, are unreasonably expensive (typically more than 25% premium), or when compliance would be inconsistent with the public interest. The Office of Management and Budget reviews waiver requests, and approval rates have declined since 2023.
The cost implication is straightforward: domestic materials cost more. Domestic hot-rolled structural steel runs 8-15% above import prices. Domestic ductile iron pipe carries a 10-20% premium. Factor this into your estimates. Check current material prices to track domestic steel, lumber, and concrete costs before finalizing bids.
Timeline: What Is Coming in 2026-2028
Contractors planning their pipeline for the next two to three years should understand which IIJA programs are peaking, which are ramping up, and which are winding down.
FHWA Bridge Formula Program: Year 4 of 5. This is peak funding for bridge repair and replacement. State DOTs have their bridge programs fully staffed and are letting contracts at the highest annual rate since the program began. If you do bridge work, the next 18 months are the window.
EPA Water Infrastructure: Year 3 of disbursement through State Revolving Funds. The programs are now fully operational — the early administrative delays are behind us. States are drawing down their allocations and cities are bidding projects. Lead pipe replacement programs are entering their highest-volume phase.
BEAD Broadband: States completed planning in 2024-2025 and are entering the construction phase. The first large-scale fiber installation contracts are being awarded now, with construction continuing through 2028-2029. This is a new market that did not exist at this scale three years ago.
Grid Resilience (DOE): GRIP and other grid programs are entering Phase 2 construction awards. The first round of planning and engineering grants has produced shovel-ready transmission and distribution projects. Construction awards will accelerate through 2027.
EV Charging (NEVI): States are in Year 3 of their buildout plans. The initial focus on interstate corridor stations is giving way to community charging in urban and rural areas. The second wave of construction is starting.
This is not slowing down. Most major IIJA programs have two to three years of peak spending remaining. The contractors who position themselves now — building relationships with state agencies, growing bonding capacity, and monitoring the right bid channels — will have a multi-year pipeline of publicly funded work.
The infrastructure bill was designed to create sustained construction demand over a decade. We are in the middle of that decade. The money is real, the projects are real, and the contractors who understand the system are building their businesses on it.
FAQ
Is the infrastructure bill still being funded?
Yes. The IIJA was signed in November 2021 with funding authorized through 2026 for formula programs and 2028 for discretionary grants. As of early 2026, $312 billion of the $550 billion in new spending has been disbursed. The remaining $238 billion in new spending is appropriated and flowing. No Congressional reauthorization is needed until 2027 at the earliest, and most discretionary programs have awards extending through 2028.
How do I find infrastructure contracts in my state?
Start with your state DOT website for highway and bridge work — every state DOT publishes upcoming lettings and bid solicitations. For water and wastewater projects, check your state's EPA revolving fund program, which maintains a list of funded projects and awarding municipalities. For broadband, check your state broadband office (find it at BroadbandUSA.gov). For federal direct contracts, use Buildermuse's federal bid tracker, which aggregates SAM.gov construction opportunities across all states and NAICS codes.
Do I need special certifications for infrastructure work?
Requirements vary by project type and funding source. Federal highway work requires contractors to be prequalified with FHWA or the relevant state DOT. Water and wastewater projects may require specific state environmental or utility contractor certifications. Nearly all federally funded construction requires prevailing wage compliance under Davis-Bacon. Performance and payment bonds are mandatory for federal projects over $150,000 under the Miller Act. Check your state's contractor licensing board for state-specific requirements.
What is the average profit margin on infrastructure projects?
General contractors typically earn 5-10% net margin on public infrastructure work. Specialty subcontractors in electrical, mechanical, paving, and concrete can earn 10-18% depending on market conditions and project complexity. Public infrastructure margins run lower than private commercial work, but the tradeoff is significant: payment is backed by government funding (zero bad-debt risk), project volume is predictable years in advance, and prevailing wage requirements reduce underbidding pressure from low-cost competitors. For many contractors, the reliability and volume of public infrastructure work produces better annual revenue than chasing higher-margin private projects.
