H.R. 8870 and the 2026 Infrastructure Funding Cliff: What Steel, Aggregate and Short Line Rail Need to Know
A major federal transportation authorization expires September 30. Its proposed replacement promises $580 billion for U.S. infrastructure. Meanwhile, interest rates remain elevated and the Federal Reserve is headed to Jackson Hole. For steel producers, aggregate operations and short line railroads, what happens next could shape infrastructure demand—and the movement of the materials needed to build it—for years.
The next chapter of U.S. infrastructure spending is taking shape in Washington, but it isn’t finished yet.
The bipartisan BUILD America 250 Act (H.R. 8870) would authorize approximately $580 billion for surface transportation programs over five years, including highways, bridges, transit and rail. The legislation includes $473.8 billion in guaranteed Highway Trust Fund funding and $45 billion for bridges, $5 billion more than under the Bipartisan Infrastructure Law.
For industries that supply and move the physical materials behind American infrastructure, those aren’t abstract numbers.
Highways require crushed stone, sand, gravel, cement and steel. Bridges require structural and reinforcing steel, concrete and aggregate. Those materials must be produced, handled, loaded and transported. And throughout the industrial supply chain, short line and industrial rail operations connect quarries, mills, plants, terminals and customers to the broader freight network.
But there’s a problem.
The existing surface transportation authorization under the Infrastructure Investment and Jobs Act (IIJA) expires September 30, 2026, and Congress has yet to send its long-term replacement to the president.
At the same time, businesses are operating in an economy where the Federal Reserve’s target interest rate remains at 3.50% to 3.75%, inflation remains above the Fed’s 2% goal and the cost of capital continues to influence investment decisions.
That makes the current infrastructure debate bigger than H.R. 8870 alone.
For steel, aggregate and short line rail, the question is not simply how much money Washington intends to spend.
It’s how predictable that spending will be, how it will be funded, and whether the industries responsible for supplying America’s next infrastructure cycle will have the confidence and capacity to meet the demand.
What Is H.R. 8870, the BUILD America 250 Act?
Introduced in May, the BUILD America 250 Act is a bipartisan, five-year surface transportation reauthorization proposal covering fiscal years 2027 through 2031.
The House Transportation and Infrastructure Committee approved H.R. 8870 on May 22 after a 14-hour markup by an overwhelming 62-2 vote.
Among the bill’s major proposed investments are:
- $580 billion in authorized and guaranteed transportation funding
- $473.8 billion in guaranteed Highway Trust Fund funding
- $45 billion in guaranteed bridge funding
- $87.5 billion in guaranteed transit funding
- $64 billion in authorized funding for Amtrak and competitive rail grant programs
- $12 billion for a new Surface Transportation Accelerator Grant program available to local communities.
For producers and manufacturers, the significance is clear: a five-year authorization gives states and transportation agencies greater visibility into future funding, which can translate into a pipeline of road, bridge and other construction projects.
And those projects ultimately translate into demand for materials.
What Infrastructure Funding Expires September 30, 2026?
Calling September 30 the expiration date of the entire Infrastructure Investment and Jobs Act can be misleading.
What’s reaching the deadline is the five-year federal surface transportation authorization established by the IIJA for FY2022 through FY2026, including the core federal highway and public transportation programs.
That distinction matters because infrastructure spending doesn’t simply stop nationwide on October 1. Previously awarded IIJA projects and funding streams don’t all vanish simultaneously.
But Congress does need to act on the federal surface transportation programs that reach the end of their current authorization.
And this isn’t unprecedented.
The Congressional Research Service notes that previous major surface transportation authorizations—including ISTEA, TEA-21, SAFETEA and the FAST Act—expired before their successors were enacted. Congress used temporary extensions to keep federal-aid highway programs operating while negotiations continued.
2026 may be headed in the same direction.
On August 8, the Senate passed a continuing resolution by a 90-6 vote that would fund the federal government through December 11 and includes an extension for the nation’s surface transportation programs. The measure still requires House action.
In other words, H.R. 8870 isn’t necessarily dead.
But Congress is running out of time to enact a full five-year transportation bill before the existing authorization expires.
Why Is the 2026 Infrastructure Bill Stalled?
The unusual thing about H.R. 8870 is that the primary obstacle isn’t simply partisan opposition.
A 62-2 committee vote demonstrates unusually broad support for a major piece of legislation.
The challenge is getting from a House committee bill to a final law.
Surface transportation legislation touches multiple programs and jurisdictions, and the House and Senate ultimately have to agree on legislation that can pass both chambers. Funding is also an unavoidable part of that discussion.
The underlying issue is the Highway Trust Fund.
Federal highway programs have traditionally relied heavily on federal motor-fuel taxes. But dedicated revenue has not kept pace with authorized spending. Congress has increasingly used transfers from the Treasury’s general fund to close the gap.
The IIJA alone transferred $118 billion from the general fund into the Highway Trust Fund. Congressional Budget Office projections cited by the Congressional Research Service indicate a potential $149.7 billion shortfall during the five fiscal years following the IIJA’s expiration under existing assumptions.
That creates a fundamental policy question:
How does the United States maintain or increase infrastructure investment without an increasingly large gap between transportation spending and dedicated transportation revenue?
H.R. 8870 attempts to address part of the problem by introducing a new revenue stream for the Highway Trust Fund. But long-term funding remains one of the larger structural questions surrounding federal infrastructure policy.
What H.R. 8870 Could Mean for Aggregate Producers
Few industries are as directly connected to transportation construction as aggregates.
Crushed stone, sand and gravel are foundational materials for roads, bridge approaches, concrete, asphalt and drainage systems.
That makes the scale and predictability of federal highway and bridge funding particularly important to aggregate producers.
The proposed $45 billion bridge investment is notable, but the larger impact comes from maintaining a multiyear federal transportation program. State departments of transportation and contractors can plan projects farther ahead when future federal funding is predictable. Producers, in turn, have better visibility into potential material demand.
There is another important dimension for aggregate operations: transportation infrastructure is both a market and part of the industry’s supply chain.
Aggregate is heavy, and the economics of moving it matter.
Quarries and terminals rely on trucks, conveyors and, in many markets, rail to move enormous volumes of material. Short line railroads can connect aggregate-producing regions and distribution terminals with Class I networks and downstream markets.
That creates an infrastructure cycle:
Infrastructure investment drives aggregate demand. Aggregate demand drives material movement. And efficient transportation infrastructure helps producers move the material needed to build more infrastructure.
For quarry and aggregate operators, H.R. 8870 therefore isn’t just a construction spending story. It is potentially a production, material-handling and transportation capacity story as well.
Why the Steel Industry Is Watching H.R. 8870
Steel has an equally direct connection to the proposed legislation.
The American Iron and Steel Institute has publicly supported H.R. 8870, specifically pointing to the bill’s $45 billion in bridge investment—a 12% increase over prior law—and its continuation of Buy America requirements for iron and steel used in Department of Transportation projects.
Those provisions matter across the domestic steel supply chain.
Transportation projects consume structural steel, reinforcing bar, plate, pipe and fabricated steel products. Bridge rehabilitation and replacement can be especially steel-intensive.
The continuation of Buy America requirements adds another dimension. When federal transportation funding is tied to domestic sourcing requirements, infrastructure policy can influence not just the amount of steel consumed but where that steel is produced.
That means a long-term infrastructure authorization could affect planning beyond the construction industry itself.
Steel mills, processors, fabricators and service centers have their own capital expenditures, material-handling requirements and transportation needs. Increasing infrastructure demand can ripple backward through those operations.
Short Line Rail May Be the Infrastructure Story Worth Watching
Passenger rail—including Amtrak—receives considerable attention whenever federal rail spending is discussed. H.R. 8870 proposes $64 billion in authorized funding for Amtrak and competitive rail grant programs, although that funding does not have the same guaranteed status as the bill’s Highway Trust Fund-backed highway investments.
But for industrial America, short line and regional railroads deserve just as much attention.
Short lines frequently provide the first or last rail connection between industrial facilities and the national freight network.
That can include:
- aggregate quarries and distribution terminals,
- steel mills and processing facilities,
- cement and concrete operations,
- manufacturing plants,
- transload facilities, and
- industrial parks.
Many short line railroads also inherited infrastructure with significant maintenance requirements when lower-density routes were spun off by larger Class I railroads.
The American Short Line and Regional Railroad Association (ASLRRA) has specifically identified investment in track, ballast and bridges as a priority and has highlighted the importance of the Consolidated Rail Infrastructure and Safety Improvements (CRISI) grant program for upgrading and modernizing short line infrastructure.
That makes federal rail policy relevant well beyond Amtrak.
If infrastructure spending increases the amount of stone, steel, cement and other heavy materials moving through the economy, the railroads serving the facilities that produce those materials become part of the infrastructure equation themselves.
Class I railroads remain important to that national freight network, of course. But at the local and industrial level, a short line may be the railroad actually spotting cars at a plant, serving an aggregate terminal or connecting a mill with a Class I interchange.
For industries moving high-volume, heavy commodities, that distinction matters.
Authorization Isn’t the Same as Appropriation
There’s another wrinkle rail operators should watch.
Not every dollar “authorized” by Congress is guaranteed to be spent.
H.R. 8870 proposes approximately $64 billion for Amtrak and competitive rail grant programs, but passenger-rail advocates have already raised concerns that the legislation does not provide the same guaranteed advance funding structure that supported passenger rail investment under the IIJA.
That distinction illustrates an important point for the entire infrastructure debate:
Authorization creates permission to spend. Appropriation provides the money.
For companies making long-term equipment and capacity decisions, predictability can matter almost as much as the headline funding number.
Where Does the Federal Reserve—and Jackson Hole—Fit In?
At first glance, a Federal Reserve symposium in Wyoming might seem disconnected from a surface transportation bill in Washington.
For industrial companies, it isn’t.
At its July 29 meeting, the Federal Open Market Committee maintained the federal funds target range at 3.50% to 3.75%. The vote was 9-3, with three members favoring a quarter-point increase. The Fed also said inflation remained elevated relative to its 2% goal, while capital investment and productivity growth remained strong.
Attention now turns toward the Federal Reserve Bank of Kansas City’s annual Jackson Hole Economic Policy Symposium.
Jackson Hole is not an FOMC rate-setting meeting, but comments from Federal Reserve officials there are closely watched for signals about the direction of monetary policy.
That matters to heavy industry because federal infrastructure funding is only one side of the investment equation.
A five-year transportation authorization can create demand.
But producers and transportation companies still have to decide whether to invest in: new production capacity, plant improvements, locomotives, track, terminals, railcars, cranes, material-handling systems, mobile equipment and automation.
The cost of borrowing affects those decisions.
That creates an unusual economic intersection in 2026:
Fiscal policy is attempting to provide long-term infrastructure investment while monetary policy remains focused on controlling inflation.
For steel mills, aggregate producers and short line railroads, the interaction between the two could be nearly as important as either policy viewed by itself.
Infrastructure Spending Ultimately Has to Become Physical
Washington debates infrastructure in billions of dollars.
Industry builds it in tons.
A federal highway authorization ultimately becomes crushed stone, asphalt, concrete and steel.
Those materials have to be quarried or manufactured.
They have to be loaded.
They have to be transported.
They have to be unloaded and handled.
And that is why the H.R. 8870 debate reaches far beyond Washington.
The bill’s future could help determine the pace of transportation construction for the next five years. The September 30 authorization deadline determines how urgently Congress must act. Federal Reserve policy influences the economics of private investment. And America’s steel, aggregate and freight rail industries provide much of the physical capacity necessary to turn federal infrastructure dollars into completed projects.
The immediate question is whether Congress can move from a bipartisan committee agreement to a final long-term surface transportation law.
The longer-term question may be even more important:
If America commits hundreds of billions of dollars to its next infrastructure cycle, are the industries that produce, handle and move the materials ready for what comes next?
