If you have followed the last two years of transit funding news — Pennsylvania's serial stopgaps, Illinois standing up a new regional authority, the Bay Area putting a sales tax on the November ballot — you have been reading stories about operations: the money that pays drivers, buys diesel, and keeps the lights on in a maintenance bay. The Capital Investment Grant program is the other half of the ledger. It is the federal government's single largest source of money for building new rail lines, bus rapid transit corridors, and capacity upgrades, and it operates on a completely different logic — multi-year, competitive, rated, and governed by a statute most riders have never heard of. It is also, as of this fall, remarkably quiet. Congress appropriated the money. The Federal Transit Administration rated the projects. And then, for well over a year, almost nothing got signed.
Here is how the pipeline actually works, where the valve closed, and why the distinction matters more than the headlines suggest.
What the Capital Investment Grant Program Actually Is
The program lives at 49 U.S.C. §5309 and is universally shorthanded as CIG, though most people still call the whole thing "New Starts" after its largest track. It is discretionary, not formula-based. A transit agency does not receive CIG money because of its population or its route miles; it receives CIG money by entering a structured, multi-year federal process and surviving every gate along the way.
The scale is substantial. The FY2025 CIG appropriation was $3.805 billion, according to the Government Accountability Office's June 2025 review. As of FY2025 there were 93 active CIG projects across 61 project sponsors, a count GAO drew from FTA and APTA dashboard data published in November 2024. APTA maintains a recurring CIG Project Pipeline Dashboard that tracks those projects one by one, including how many federal dollars each sponsor has requested — the closest thing the public has to a live scoreboard.
Three Tracks, Three Thresholds
CIG is not one program but three, divided by size and purpose.
- New Starts covers projects with a total capital cost of $400 million or more, or that are seeking $150 million or more in CIG funds. This is the light rail extension, the new subway line, the full BRT buildout.
- Small Starts covers projects below both of those thresholds — typically bus rapid transit, streetcars, and modest rail extensions.
- Core Capacity is the least understood of the three. It funds work in an existing fixed-guideway corridor that is at or near capacity, and it carries a hard performance requirement: the project must increase corridor capacity by at least 10 percent. Critically, it explicitly excludes projects that are only buying rolling stock or only addressing state of good repair. You cannot use Core Capacity to replace worn-out signals and call it a day; the work has to demonstrably move more people.
That exclusion is the source of a lot of confusion among riders who assume that any big federal transit check is "New Starts money." Most state-of-good-repair work flows through entirely different formula programs.
Two Statutory Phases Before a Shovel Moves
New Starts and Core Capacity projects must pass through two legally defined phases.
Project Development comes first and carries a two-year statutory limit. During it, the sponsor adopts a Locally Preferred Alternative — the specific mode, alignment, and station set chosen out of the studied options — completes its review under the National Environmental Policy Act, and advances design to roughly 10 to 30 percent.
Engineering follows and typically runs two to four years. Here the sponsor pushes design past 90 percent, finalizes its local funding match, and produces a detailed, defensible cost estimate. Only after Engineering can a project receive a construction grant agreement.
Small Starts, by design, skips the Engineering phase entirely and moves from Project Development straight toward construction. That structural shortcut is the single biggest reason smaller projects deliver faster.
How a Project Earns Its Rating
Everything in CIG runs on ratings. Every project is scored Low, Medium-Low, Medium, Medium-High, or High, and a project must hold at least an overall Medium rating to advance toward a construction grant agreement. Below Medium, the process simply stops.
Two Co-Equal Dimensions
The overall rating is built from two halves, weighted equally.
- Project Justification aggregates six sub-criteria: mobility improvements, environmental benefits, congestion relief, economic development effects, land use, and cost-effectiveness.
- Local Financial Commitment evaluates whether the non-federal money is real — committed, available, and backed by an agency with the financial capacity to operate the thing once it opens.
The second half is where a lot of promising corridors quietly die. A region can have a beautifully justified line and still stall because its local revenue source is contingent on a ballot measure that has not passed yet. That is precisely the tension playing out in the Bay Area's SB 63 campaign and in Pennsylvania's repeated failure to establish dedicated transit funding: operating instability is a capital-program problem too.
The Match Math Nobody Expects
Statutorily, New Starts CIG funding is capped at 60 percent of project cost, with total federal participation from all sources capped at 80 percent. Small Starts and Core Capacity can go up to 80 percent CIG.
In practice, those ceilings are theoretical. Across FY2020 through FY2024, New Starts federal shares frequently landed in the 30 to 50 percent range — well below what the law allows. The reason is competitive, not legal: because Local Financial Commitment is half the rating, bringing more local money to the table makes an application stronger. Sponsors voluntarily ask for less than they could in order to score better. It is a quietly elegant incentive, and it also means CIG dollars leverage considerably more local investment than the statute requires.
FFGAs, SSGAs, and the $25 Million Line
The final instrument matters enormously for understanding the current freeze. Any New Starts or Core Capacity project receiving a federal commitment of $25 million or more requires a Full Funding Grant Agreement (FFGA) — a binding, multi-year contract in which the federal government commits to a specific dollar amount over a specific schedule. Small Starts projects use a lighter instrument, the Small Starts Grant Agreement (SSGA).
The FFGA is the moment the money becomes real. Everything before it is process. Remember that distinction; it is the whole story of 2026.
The Clock: Eight to Fifteen Years
FTA's own Annual Report on Funding Recommendations data shows observed concept-to-opening timelines of roughly 8 to 15 years for New Starts projects, and 4 to 7 years for Small Starts. Those are not outliers. They are the norm.
Why Timelines Stretch
GAO's 2020 review (GAO-20-512) found that sponsors of most of the then-66 active CIP projects reported delays in at least one part of the development process. Causes compound: environmental review, local funding referenda, utility relocation, right-of-way acquisition, and the simple reality that a ten-year project passes through at least two or three local political administrations.
What GAO Found in 2025
The most recent review, GAO-25-107672, published June 18, 2025, is titled Capital Investment Grants Program: DOT Should Tailor Technical Assistance Provided to New and Potential Applicants. GAO surveyed all 61 project sponsors and got an 87 percent response rate, and interviewed APTA, the CIG Working Group, and the Eno Center for Transportation.
The headline finding was unglamorous but consequential: more than a third of sponsors said FTA's communication about timelines is not always clear. GAO recommended FTA tailor its technical assistance to new and less experienced applicants, and reiterated an unimplemented 2020 recommendation on timeline transparency. DOT did not concur. For a first-time sponsor — a mid-size city attempting its first BRT line — that opacity is a real barrier to entry.
Do the Predictions Hold Up?
GAO's April 2023 report (GAO-23-105479) found that CIG cost predictions have improved over time, which is a genuinely good-news finding in a field full of cost-overrun horror stories. Ridership prediction accuracy was harder to assess: COVID-19 scrambled the post-opening comparison baseline, since projects opening in 2020-2022 faced demand conditions no forecast anticipated. FTA continues to issue periodic Predicted vs. Actual reports. Worth noting: GAO's CIG review is now a statutory biennial requirement under the IIJA, so this oversight cadence is locked in.
The Quiet Freeze of 2025-2026
Now the part that has transit finance people genuinely unsettled.
Zero New Full Funding Grant Agreements
The New York Times reported on July 27, 2026, under the headline "Congress Budgeted Billions for Big Transit Projects. Trump Isn't Spending It.," that since the administration took office, FTA had not signed a single new FFGA under the CIG program. One characterization quoted in the piece put it plainly: "It's hard to look at the last year and see anything other than a deliberate slowdown of these grants." A construction-industry trade outlet, Westside Construction Group, separately reported that the FFGA drought had stretched past 14 months.
Planetizen, citing the Times reporting in August 2026, described the situation as the administration "simply declining to award over $7 billion" in transit funds Congress had already allocated through CIG. The key nuance: grants are not being formally canceled. The money is simply not being obligated.
The Rewritten Environmental Criterion
Alongside the slowdown came a substantive change in the rules. The November 2025 CIG Policy Guidance redefined the environmental benefits justification criterion. The prior approach relied on vehicle-miles-traveled reductions and the social cost of carbon. The new approach bases the rating on EPA National Ambient Air Quality Standards attainment status: projects in non-attainment areas rate High, projects in attainment areas rate Medium.
This is the clearest documented rollback of a climate-specific metric in the program. It is not nonsensical — air quality non-attainment is a legitimate, legally grounded measure of environmental need — but it systematically advantages corridors in already-polluted regions and removes carbon reduction as a scoring consideration entirely. A further guidance update has been proposed for October 1, 2026.
Forty-Two Senators and $1.9 Billion
On August 13, 2026, Senators Adam Schiff, Alex Padilla, and Elizabeth Warren, joined by 39 Democratic colleagues, published a letter accusing FTA and OMB of "holding Blue State infrastructure funding hostage." They cited $1.9 billion in unobligated and unallocated CIG funds ready to spend, and alleged that red-state projects were advancing while blue-state projects stalled.
That framing is politically potent, and it is also worth testing against the evidence — because the evidence is more complicated.
Austin's Counterexample: The Pipeline Still Moves
If the CIG program were frozen end to end, Austin's Project Connect would not be where it is.
The Highest Rating in the FY2026 Cycle
The Austin Transit Partnership and CapMetro light rail program received a Medium-High project rating — the highest awarded in the FY2026 cycle. It completed its NEPA Final Environmental Impact Statement in January 2026, reportedly the first major New Starts project to hit the two-year statutory NEPA deadline. By spring 2026, it had moved into construction contracting. The roughly $7 billion program is competing for approximately $4 billion in federal funding.
The Bottleneck Is One Signature
Austin demonstrates something important: FTA's technical machinery is still running. Projects are being rated. NEPA documents are being issued — faster than they used to be, in at least one case. Engineering is advancing. Sponsors are still being admitted to Project Development.
What has stopped is the politically controlled step: the decision to sign a new Full Funding Grant Agreement. That is a narrower and more precise diagnosis than "the administration killed New Starts," and the precision matters. A rated, NEPA-complete, 90-percent-designed project that is waiting on an FFGA can be funded very quickly whenever the signature comes. A pipeline that had collapsed at the technical level would take years to rebuild. The current situation is a logjam, not a demolition — which is both reassuring and, for sponsors paying carrying costs on contractor commitments, expensive.
What Happens After December 11
CIG's near-term future is tangled up in the broader reauthorization mess.
A Stopgap, Not a Bill
The Senate passed a stopgap on August 8, 2026, extending IIJA surface transportation programs only through December 11, 2026, without a full reauthorization. That leaves CIG's post-2026 statutory and funding framework unresolved. Advocacy groups estimate that if advance appropriations are not preserved during the extension window, the result would be roughly a 20 percent cut to transit investment and an 83 percent cut to passenger rail investment. We covered the mechanics of that cliff in detail in our piece on the IIJA stopgap and advance appropriations.
The Reform Bill That Isn't Moving
The BUILD America 250 Act (H.R. 8870) would, per APTA's June 15, 2026 fact sheet, reform CIG eligibility and evaluation criteria across all three tracks and authorize $580 billion over five years, including $87.6 billion for transit. It has no Senate companion and remains stalled. Our full explainer on the bill walks through what it would and would not change.
Why the Stakes Are Higher Than the Line Items
APTA's economic case is worth stating plainly, because it reframes a stalled pipeline as something other than a bureaucratic inconvenience. Every $1 billion invested in public transit generates, by APTA's estimates:
- roughly $5 billion in economic returns
- about 41,400 jobs
- $251 million in tax revenue
- $3.6 billion in access value
Apply that to $7 billion in unobligated CIG funds and the opportunity cost is not abstract. It is construction payrolls not met, contracts not let, and corridors not opened — in regions that already voted to tax themselves for the local share.
What to Watch Next
The CIG program is the clearest available test of a question that runs through every story on this blog right now: what happens when the technical consensus on a project is solid but the political will to execute is absent? Illinois answered its version of that question by creating a new governance structure. Pennsylvania has answered it, repeatedly, by punting. At the federal level, the answer so far has been to let a fully functioning process run right up to the final signature and then stop.
Three things are worth tracking over the next several months. First, whether any FFGA gets signed before the December 11 extension deadline — a single signature would change the entire narrative. Second, the proposed October 2026 CIG guidance update, which will show whether the November 2025 criteria changes were a one-time recalibration or the start of a broader rewrite. Third, Austin: if a Medium-High-rated, NEPA-complete, construction-ready project competing for $4 billion cannot get an agreement, the problem is not about project quality at all, and everyone in the pipeline will know it.
For riders, none of this shows up on a schedule board for years. But the mechanics are worth understanding, because when a new light rail line opens in 2035, the decisive moment will not have been the ribbon-cutting or the groundbreaking. It will have been an unglamorous contract signature, or its absence, sometime around now.
