Congress Punted on Transit Funding — And the Fine Print Could Cost Agencies Billions

On August 8, 2026, the Senate did what Congress almost always does when a big transportation bill is about to expire: it punted. Rather than reauthorize the Infrastructure Investment and Jobs Act — the sweeping 2021 law that has bankrolled everything from rural bus replacements to the Second Avenue Subway extension — lawmakers passed a 10-week continuing resolution stretching IIJA's surface transportation programs to December 11, 2026. The House concurred, the President signed, and Washington moved on. But buried in what looks like a routine "status quo" extension is a technical omission that transit finance officers have been dreading for months. Unless the fine print is fixed, the stopgap amounts to an effective 20% cut in transit investment and an 83% cut in passenger-rail investment — not because Congress voted to cut anything, but because it forgot (or declined) to preserve the one budgetary mechanism that lets multi-year capital projects actually happen.

The Deadline Congress Missed

IIJA, signed on November 15, 2021, was always going to expire on September 30, 2026. That date has been on every transit CFO's calendar for nearly five years. The pipeline for a replacement bill did exist: in May 2026, the House Transportation and Infrastructure Committee, chaired by Rep. Sam Graves, advanced the BUILD America 250 Act (H.R. 8870) by a bipartisan 62–2 vote. The $580 billion, five-year package is imperfect — it cuts guaranteed transit authorizations by about 14% from IIJA's inflation-adjusted baseline and, more alarmingly, zeroes out all guaranteed passenger-rail funding — but it exists. I unpacked it in detail in a previous post.

The Senate never produced a companion. The Environment and Public Works Committee, chaired by Sen. Shelley Moore Capito, has not started markup — a reflection of both the Senate's crowded fall calendar and the absence of the same bipartisan pressure that drove the House bill. With the clock at zero, the stopgap was the only politically viable move. But a stopgap is not neutral — it interacts with IIJA's underlying budget architecture in ways that most headline coverage has missed.

What Actually Got Extended

The continuing resolution keeps the Federal Transit Administration writing formula-grant checks at current-year rates. Section 5307 urban formula money keeps flowing to New York, Chicago, Los Angeles, and everywhere in between. Section 5311 rural formula grants keep small operators solvent through the fall. FY26 apportionments — $14.6 billion in FTA formula funds, a 5% increase over FY25 — have already gone out.

What the stopgap does not clearly extend is the machinery for committing federal dollars to projects that won't break ground for years. That's where the trouble lives.

The Advance-Appropriations Problem, in Plain English

To understand why a 10-week extension can cause a multi-year problem, you have to understand one of the least glamorous concepts in federal budgeting: advance appropriations, sometimes called contract authority.

Most federal spending works on a one-year cycle: Congress appropriates money for FY2027, agencies spend it in FY2027, done. Advance appropriations flip that. They are budget authority provided now, in current law, that automatically becomes available for obligation in a future fiscal year — without requiring a separate annual vote. IIJA structured tens of billions of transit and rail dollars this way, precisely because building a light rail extension or replacing a fleet of railcars is not a one-year project.

Why Transit Cannot Function Without It

Consider what actually happens when a city wants to build a subway extension, a BRT corridor, or a commuter-rail infill station:

• Planning, environmental review, and engineering take 3 to 10 years.
• The FTA's Full Funding Grant Agreement (FFGA) — the legal instrument that commits federal money to a Capital Investment Grants (New Starts) project — is signed years before shovels move.
• Agencies then sell municipal bonds against expected federal draws, at interest rates that reflect the certainty of those future dollars.

Every link in that chain requires legally authorized out-year funding. Without advance appropriations, the FTA cannot sign new FFGAs. Underwriters cannot price bonds against uncertain future discretionary appropriations. Boards cannot approve budgets for projects whose federal match might evaporate.

A standard CR at current-year rates does not automatically carry forward IIJA's advance-appropriations structure. Unless the stopgap text explicitly preserves those provisions — and the August 8 bill does not, cleanly — the pipeline for new multi-year capital commitments simply stops filling. Nothing gets canceled. Nothing gets defunded on paper. It just quietly freezes.

Where the 20% and 83% Numbers Come From

Transportation for America and APTA have both warned that the effective investment gap during the extension period comes to roughly 20% for transit and 83% for passenger rail. Those aren't cuts to headline authorization numbers — they measure the delta between what agencies expected to be able to obligate under IIJA's advance-appropriations regime and what a stripped-down CR actually delivers. For Amtrak in particular, where the vast majority of federal support flows through advance appropriations, an unpatched stopgap effectively turns the spigot down to a trickle.

The Programs on the Line

The Congressional Research Service and FTA's own program documentation make clear how uneven the exposure is across IIJA's transit portfolio.

The state-of-good-repair line is particularly painful in context. The National Transit Database pegs the current SOGR backlog at $105.3 billion — $69 billion for rail and $32 billion for bus. Every quarter that Section 5337 commitments stall is a quarter that backlog grows.

What This Looks Like at the Agency Level

Federal budget mechanics get abstract fast. The consequences do not.

SEPTA and MTA: Different Scales, Same Squeeze

Philadelphia is already living the worst-case scenario. In August 2025, SEPTA implemented the most severe service cut in modern American transit history: 32 bus routes and 5 Regional Rail lines eliminated, plus a 9 p.m. rail curfew, in response to a $213 million operating deficit. Pennsylvania still has no dedicated recurring state transit funding — a fight tracked at length in this post on the FY27 budget deadline and this one on dedicated funding. Any effective federal cut is additive to a system that has already run out of runway.

The MTA, by contrast, is the largest single FTA formula recipient — well over $1.5 billion a year. A 20% effective cut translates to more than $300 million annually against its $68.4 billion 2025–2029 capital plan. Manhattan's congestion pricing program, now dedicating roughly $1 billion a year to the MTA capital program (see year-one results), provides partial insulation. It does not close the gap on the multi-year capital side, where FFGAs for East Side Access follow-ons and Second Avenue Phase 2 depend on federal certainty.

BART, WMATA, MBTA: Structural Deficits Meet Federal Fog

BART is staring down a $375 million structural operating deficit. Farebox recovery has collapsed from 71% pre-pandemic to about 30% in FY25, while ridership has slid from 118 million annual trips to 52.7 million. The agency's near-term lifeline is a November 2026 ballot measure under California SB 63, the Connect Bay Area Act, which would levy a half-cent sales tax across four Bay Area counties and a 1-cent tax in San Francisco, projected at roughly $980 million a year across five counties. The ballot mechanics and funding structure are covered in depth in the balanced FY27 budget and the SB 63 measure itself. Federal capital uncertainty is not the biggest thing on BART's plate right now, but it makes every long-range plan wobblier.

WMATA is running a ~$750 million operating gap with fare recovery around 24%. The MBTA projects a $600 million deficit by FY2028, with fare recovery near 17% and an active FTA safety consent agreement forcing capital spending it cannot delay. Both agencies rely on Section 5337 State of Good Repair funds committed multiple years out — precisely the flows the stopgap freezes.

CTA: The Illinois Cushion

Chicago is the outlier in a good way. The Illinois NITA Act, enacted in June 2026, provides roughly $1.5 billion a year in dedicated state funding across the RTA system — the kind of durable local commitment SEPTA and BART are still fighting for. The mechanics are explained in this post. CTA is still exposed on the federal capital side, but its operating base is the most secure among peer legacy systems.

Amtrak: Record Ridership, Cliff-Edge Funding

Amtrak just posted its best year ever: 34.5 million passengers in FY25, up 5% year over year; $2.7 billion in revenue; 6.9 billion passenger-miles. It is mid-delivery on the Airo trainset replacement program with Siemens (more in this post) and continuing to grow its state-supported corridor network, including the two-year-old Borealis service. The BUILD America 250 Act would zero out guaranteed rail funding entirely. The stopgap, by failing to preserve advance appropriations, previews what that world feels like — an 83% effective haircut on the money Amtrak was counting on to match state corridor investments and finish fleet replacement.

A History Lesson: The SAFETEA-LU Gap

None of this is unprecedented. SAFETEA-LU, the predecessor surface transportation law, expired on September 30, 2009. Congress passed 10 short-term extensions over 33 months before MAP-21 was finally enacted in July 2012. The Eno Center for Transportation, which analyzed the episode in detail, concluded that each successive extension narrowed the political window for the next — urgency dissipated, but the policy problems compounded.

During that 33-month stretch:

• No new multi-year capital agreements could be signed.
• The New Starts pipeline stalled; projects in engineering could not advance to FFGAs.
• Major light rail and BRT projects experienced 18-to-36-month delays.
• States and localities bridged federal uncertainty with local financing at higher interest rates, quietly transferring costs from the federal balance sheet to municipal ones.

The parallels to today are uncomfortably tight. The BUILD America 250 Act is roughly the analog of what MAP-21 eventually became — a bipartisan committee product waiting for a Senate that isn't ready. The 10-week CR is extension number one.

The Path to December 11 — and Beyond

Four plausible scenarios sit on the table for the next 10 weeks.

Option A — Full reauthorization by December 11. The BUILD America 250 Act clears the House floor, the Senate produces a companion, conferees resolve differences, and a five-year bill is signed. Very low probability. Senate EPW has not begun markup.

Option B — Amended stopgap that explicitly preserves advance appropriations. The advocacy community's minimum ask. Could move via unanimous consent if leadership signs off. Moderate probability with sustained pressure from APTA, T4America, and agency CEOs.

Option C — Another short-term extension. The SAFETEA-LU playbook. Most likely near-term outcome.

Option D — Full lapse. Formula grants stop, no new project agreements can be signed, contract authority evaporates. Technically possible; politically untenable. But "politically untenable" has aged badly in recent Congresses.

Underneath all four options is a harder deadline: the Highway Trust Fund is projected to hit insolvency by roughly Q2 FY2027 without action, according to CBO. Transit shares that fund's Mass Transit Account. No amount of clever CR drafting fixes a trust fund running dry.

What Readers Can Actually Do

If you care about transit — whether you ride SEPTA, wait for a BART train, or just want your city's bus system to keep the doors open — the next 10 weeks matter more than most people realize. A few concrete steps:

• Watch the December 11 vehicle. Whether it preserves advance appropriations is a single technical question worth more than any headline authorization number in the interim.
• Follow APTA and T4America action alerts. Both organizations have direct channels to committee staff and deploy grassroots pressure effectively at exactly these moments.
• Contact your lawmakers. If your senator sits on EPW or your representative on House T&I, a constituent message specifically referencing "advance appropriations" and "FFGA authority" lands very differently than a generic pro-transit note.
• Track your local agency's capital plan. Boards are already stress-testing project timelines against federal uncertainty; public comment periods this fall will shape which projects survive.

Congress did not cut transit on August 8. It did something subtler and, in some ways, more consequential: it left the machinery of multi-year investment in a state of suspended animation. The systems most exposed — SEPTA, BART, Amtrak, MBTA — are the ones already balancing on the thinnest financial margins. The broader fiscal cliff has not gone away. December 11 will tell us whether Washington remembered to bring a bridge.
