A practical 2026 guide to how Georgia may fund a $1.8B I‑75 project — bonds, tolls, grants or taxes — and what each means for your wallet.

Will Georgia Fund $1.8B With Bonds or Taxes? A Taxpayer’s Guide to State Infrastructure Funding

Hook: If you commute I‑75, pay Georgia sales tax, own property or follow municipal bonds, a proposed $1.8 billion unclogging of I‑75 in Atlanta could change your pocketbook and your commute. This guide breaks down the most likely funding paths — bonds, tolls, federal grants and taxes — explains what each means for Georgia taxpayers, and shows how similar projects were financed and what lessons to apply in 2026.

Why this matters now (2026 context)

In January 2026 Gov. Brian Kemp proposed spending $1.8 billion to add toll express lanes on I‑75 through Henry and Clayton counties — a high‑profile example of states wrestling with how to pay for large transportation projects amid higher borrowing costs and tight federal grant competition. After the post‑pandemic surge in congestion and several multi‑year toll projects around Atlanta, Georgia faces a familiar choice: shift costs to users, borrow now and spread costs across generations, rely on federal grants, or raise local/state taxes. Each choice has direct tax implications and long‑term fiscal tradeoffs for residents.

Funding options and how they work

1) Municipal bonds (state or revenue bonds)

How it works: The state issues bonds to investors to raise the full project cost up front. Bonds are repaid over time with interest from a designated revenue stream or the general fund.

General obligation (GO) bonds: Backed by the state’s full faith and credit — typically repaid from general revenues (income, sales taxes). They usually carry lower interest rates because of strong security.
Revenue bonds / toll revenue bonds: Repaid from tolls or user fees. They do not depend on the general fund but rely on traffic and toll forecasts.
Special obligation / availability bonds: Paid from specific state transportation revenues or availability payments to a private operator.

What it would mean for taxpayers: If Georgia issued GO bonds, debt service would be paid from the general fund — potentially crowding out other spending or increasing pressure to raise taxes in the future. If revenue bonds are used, toll payers shoulder most of the cost; taxpayers are insulated unless tolls fall short and the state steps in. Either way, issuing $1.8 billion when borrowing costs are higher than a few years ago could raise decades of interest expense.

2) Toll funding and public‑private partnerships (P3s)

How it works: The state either operates toll express lanes and issues revenue bonds secured by tolls, or partners with a private firm that finances construction in exchange for toll revenue or availability payments.

State‑operated toll lanes: Georgia already uses Peach Pass and express lanes; expanding these keeps control public but requires accurate traffic modeling.
P3 / concession model: A private investor builds and operates lanes, often for many decades. The private partner bears upfront cost and some operational risk but expects long‑term payments.

What it means for taxpayers: Tolls are direct user fees: commuters who use the lanes pay. This reduces general taxpayer exposure but raises equity concerns for lower‑income commuters and can shift congestion to untolled lanes. P3 deals can accelerate delivery but may lock the state into long payments or higher tolls long term — think Indiana Toll Road (2006) or some problematic US express‑lane concessions that required renegotiation.

3) Federal grants and discretionary programs

How it works: Federal funds (e.g., IIJA/BIL programs such as INFRA, RAISE and formula highway funds) cover part of a project. Grants rarely cover 100% of major urban highway builds and are competitive.

2026 nuance: By late 2025 many states tapped initial IIJA funding; discretionary grants remained available but competitive. Georgia could secure a sizeable federal chunk, but the state would likely still need state or local matching funds.

What it means for taxpayers: Federal dollars reduce the share Georgia must raise. They also often bring compliance and reporting obligations. But because federal grants aren’t guaranteed and take time to apply for, they are rarely the sole solution to immediate project financing.

4) Taxes and local funding (TSPLOST, sales tax, etc.)

How it works: Georgia has local options like the Transportation Special Purpose Local Option Sales Tax (TSPLOST) and county SPLOST levies. Regions vote to impose a supplemental sales tax dedicated to transportation projects.

What it means for taxpayers: A TSPLOST spreads costs among consumers in the region, including visitors, not just commuters. Because sales taxes are regressive, lower‑income households can bear a higher relative burden. Voter approval is typically required; that creates political accountability but makes certainty lower.

Realistic scenarios for Georgia’s $1.8B I‑75 plan

Given Georgia’s recent pattern of building express lanes and Gov. Kemp’s explicit reference to toll lanes, the likeliest paths blend toll financing with bonds and targeted local/state contributions:

Primary route: Toll revenue bonds + state credit support. The state issues toll revenue bonds backed by projected Peach Pass revenues and may reserve some state highway funds as a liquidity backstop.
Supplemental route: Federal grant match + local TSPLOST contribution. Georgia secures a federal competitive grant for a portion of the cost and uses local TSPLOST proceeds for matching funds.
Alternate: P3 concession or availability payment model. A private partner designs, builds and operates the lanes for a set term; the state makes availability payments or allows tolling revenue sharing.

Completely funding $1.8B through direct general‑fund appropriations or a broad state tax increase is politically unlikely in 2026 given budget pressures and competing priorities.

What the numbers can look like — an illustrative bond scenario

To make the implications concrete: if Georgia issued $1.8 billion in 30‑year fixed‑rate bonds at a 4.5% effective interest rate, the annual debt service would be roughly $110 million per year — or about $3.3 billion total paid over 30 years (principal + interest). That’s an illustration: actual rates, terms and amortization will affect the final cost.

Takeaway: Borrowing smooths the upfront hit but nearly doubles program cost because of interest. If the state covers that debt service from the general fund, it competes with K‑12 education, Medicaid, and public safety for space in the budget.

Historical precedents and lessons

Georgia’s own experience

Georgia has expanded express lanes over the last decade through Peach Pass and the GDOT/SRTA partnership model. These projects used a mix of toll revenue bonds, federal grants and state appropriations. The key lessons: traffic can take longer to build than projected, and revenue shortfalls often require contingency plans.

Out‑of‑state cautionary tales

I‑77 HOT lanes (North Carolina): A concession model with a private operator faced public backlash and legal disputes over toll rates and traffic impacts, illustrating political risk in P3s.
Indiana Toll Road lease (2006): A long‑term concession generated significant near‑term cash for the state but passed future toll control to a private operator for decades — a caution about irreversible deals.
Urban express lane projects (various states): Several states issued toll revenue bonds based on optimistic traffic forecasts, then needed public subsidies when user adoption lagged.

Tax implications for Georgia residents

If bonds are GO bonds or paid from the general fund

GO bonds increase the state’s debt obligation. To cover debt service the legislature may reallocate spending or consider tax increases (sales, income or selective surcharges). For individual taxpayers, the most direct impacts can include:

Pressure on future budgets that could limit services or trigger tax adjustments.
Potential effects on credit ratings if Georgia’s overall debt profile worsens; higher borrowing costs across future issuances could raise taxes indirectly.

If revenue/toll bonds or tolls are used

Toll financing shifts costs to commuters using the new lanes. Toll payments are not tax deductible for most commuters. For people who avoid the lanes, the fiscal impact is indirect — reduced strain on state budgets — but equity effects matter: lower‑income commuters who can’t afford tolls may face longer drives or no access to faster lanes.

If TSPLOST or sales taxes fund the match

Regional sales tax increases spread costs among shoppers and visitors, not just commuters. However, sales taxes are regressive — hitting lower‑income households relatively harder. If you live in a county that votes on a TSPLOST referendum, your ballot will matter.

Municipal bond investors

If Georgia issues tax‑exempt municipal bonds, interest income is generally exempt from federal income tax and may be exempt from Georgia state taxes for Georgia residents. That makes municipal bonds attractive to income‑seeking investors — but they carry credit, interest‑rate and project risks. Revenue bonds tied to tolls typically trade at higher yields due to user‑revenue risk compared with GO bonds.

Practical, actionable guidance for taxpayers and investors

Commuters: Track the I‑75 proposal closely. If toll lanes are built, evaluate commuting options (carpooling, transit) and estimate monthly Peach Pass costs. Use your commute time and likely toll costs to decide whether a toll lane saves value.
Voters in the region: Watch for TSPLOST referenda and county commission meetings. Local votes decide whether the burden shifts to sales taxes.
Property owners: Monitor county bond referenda and potential reallocations in the state budget that could affect local service funding.
Investors in municipal bonds: Read any bond official statement (OS) before purchase. For revenue bonds, look at traffic projections, debt service coverage ratios, and any state backstop. Consider laddered muni funds or insured muni issues if you want to reduce single‑issuer risk.
Tax planners: If you expect to buy Georgia muni bonds, confirm state tax treatment of interest. Consult a CPA for how bond interest fits into your taxable income profile.
Active citizens: Attend GDOT or county hearings, submit comments on traffic and equity impacts, and ask for independent traffic modeling and contingency plans for revenue shortfalls.

Questions to ask as this proposal moves forward

Will the project be financed with GO bonds, revenue bonds, a P3, or a mixture?
How much federal grant money is expected and what contingencies exist if grants fall short?
What are the toll rate assumptions and the break‑even traffic projections?
Are there explicit protections for low‑income commuters or alternatives like expanded transit?
How will this issuance affect Georgia’s bond ratings and future borrowing costs?

What to watch in 2026

Watch three moving parts: legislative authorization (can the state legally issue the chosen debt type?), federal grant awards through 2026 discretionary cycles, and GDOT traffic modeling updates. The municipal bond market’s appetite in 2026 — shaped by interest‑rate policy, state credit spreads and investor demand for tax‑advantaged income — will determine borrowing costs. Public sentiment and regional votes on any TSPLOST will determine how much cost is shifted to sales taxes.

“Tolls can protect general taxpayers but create equity and long‑term cost questions; bonds smooth upfront costs but carry interest that doubles program cost over decades.”

Bottom line

Georgia’s $1.8 billion I‑75 proposal will almost certainly be financed through a hybrid approach: tolling and revenue bonds anchored by smaller federal grants and possible local sales‑tax matches. That arrangement protects most non‑users from direct charges but shifts the burden to commuters and future toll payers. If the state leans on general obligation borrowing or a local TSPLOST, broader taxpayer pockets will contribute — either today via sales taxes or tomorrow via diverted general revenues.
