Which Spanish Fort household will pay more to cross into Mobile in the late 2030s: the one that drives the Bayway every weekday, or the one that crosses a couple of times a week? Under the toll schedule Alabama adopted this September, the second household's bill can keep climbing while the first one's monthly price holds still for a decade.
That gap is written into the financing documents for the I-10 Mobile River Bridge and Bayway project. Crews broke ground on October 2, 2026. ALDOT projects that tolling will begin in late 2031, and no tolls will be collected before the new bridge and the Phase One improvements open. The rates and the rules for raising them are already set, though. If you're comparing Spanish Fort with other Eastern Shore towns and plan to work in Mobile, you can price that commute today.
The Price That Stays Put
At opening, a standard passenger vehicle has four ways to pay, according to AL.com's toll explainer:
- ALGOpass monthly unlimited: $60 a month
- ALGOpass per trip: $3
- Compatible transponder from another toll system: $7.70
- Pay-by-plate: $15.40
ALDOT's own example has a commuter making 44 one-way trips a month, which works out to about $1.36 per trip on the unlimited plan. The bigger detail is what happens to each rate after opening day. The $60 monthly plan is fixed for the first 10 years after tolling begins, which AL.com puts at unchanged through 2041. The $3 per-trip rate doesn't get that protection.
NBC 15's report on the bond documents spells out the formula. Under the toll policy adopted September 8, rates go up automatically every January 1, starting the first year after tolling begins. For the first 10 years, each increase is 5% or the annual rise in the Southern region's Consumer Price Index, whichever is greater. After that, the floor drops to 2.5%, or regional inflation if that's higher. The $60 monthly plan doesn't change during those first 10 years and then follows the same formula.
So the breakeven between paying per trip and buying the pass keeps moving. At opening, the pass pays for itself at 20 one-way crossings a month. Every January, that number drops.
| Annual increases since tolling began | ALGOpass per-trip rate at the 5% minimum | One-way trips a month where $60 pass breaks even |
|---|---|---|
| None, opening rate | $3.00 | 20 |
| 2 | $3.31 | about 18 |
| 4 | $3.65 | about 16 |
| 6 | $4.02 | about 15 |
| 8 | $4.43 | about 14 |
| 10 | $4.89 | about 12 |
The figures in this table are our own arithmetic, using the 5% minimum that the policy sets for the first decade. 5% is the lowest the increase can be. In any year when Southern-region inflation runs higher, the per-trip column climbs faster and the breakeven falls sooner.
Why the Schedule Is Hard to Soften
You might expect a toll schedule to bend to local politics. This one has limits built in. NBC 15 reports that while the federal TIFIA loan is outstanding, the toll authority can't reduce, limit or postpone the increases without the federal lender's approval. The bond documents also allow extra adjustments if revenue falls short of debt-coverage requirements. In that case, the state transportation director can hire an independent traffic-and-revenue consultant and adopt that consultant's recommended rates.
The loan is large. ALDOT says the financing includes a $2.52 billion TIFIA loan, plus bonds sold to investors in September, and together they fund the $3.2 billion Phase One construction cost. AL.com reports an all-in Phase One budget of $4.15 billion once right-of-way, utilities, toll system integration, financing and capitalized interest are included.
The numbers have already moved once. The 2021 framework backed by the Eastern Shore and Mobile Metropolitan Planning Organizations called for a $2.50 maximum trip toll and a $40 monthly unlimited option. The final financing plan set those at $3 and $60. AL.com reports the change came over the summer and traces much of it to rising construction costs. Jack Burrell, chair of the Eastern Shore MPO, described local officials' position in AL.com's July coverage: "If we want a bridge, we have to live with it."
What That Means for a Spanish Fort Comparison
Once the per-trip rate starts climbing and the pass stays flat, the price of a Mobile commute depends more on how often you cross than on how far you drive. Here are two illustrations, each using the 5% minimum:
- A five-day commuter who makes about 44 one-way crossings a month pays $60 at opening and still $60 after the tenth annual increase.
- A two-day-a-week hybrid worker who makes about 17 one-way crossings a month pays roughly $51 at opening on the per-trip rate. By the fourth increase, that same month costs about $62, so the pass becomes the cheaper option. That household's cost still ends up near $60, but it gets there through increases a full-time commuter never pays.
The occasional crosser bears the escalation. That covers the one-day-a-week office visit, the weekend trip to a downtown Mobile event, and anyone who never sets up an ALGOpass account. Visiting family who drive in without a transponder would be billed $15.40 by plate. AL.com notes that pay-by-plate drivers can open an ALGOpass account and pay the $3 rate instead. ALGOpass transponders are expected to be free during the initial rollout.
Spanish Fort sits right on the corridor, and the free routes are part of the decision too. ALDOT says the Wallace Tunnel, the Bankhead Tunnel, the Africatown Bridge and the Causeway will stay toll-free. The Causeway is U.S. 90/98, which AL.com calls the Spanish Fort Causeway. According to AL.com's comparison of the two plans, the 2019 proposal would have tolled the existing Wallace Tunnel, leaving no free route along I-10. The current plan keeps all the free routes the same and tolls only the new infrastructure. That 2019 fight played out partly in Spanish Fort. AL.com reports that a public hearing on the earlier toll plan took place at the Five Rivers Delta Resource Center in August 2019.
When you tour homes, ask how many days a week you'll realistically cross, then check which route you'd use on each of those days. That gives you a clearer cost picture than any single toll rate.
The Five Years Before Anyone Pays
The toll is the long-term cost, and construction comes first. Here's the timeline so far and what's projected:
| Date | Milestone |
|---|---|
| September 18, 2026 | ALDOT announces the bond and federal loan financing is complete |
| September 25, 2026 | ALDOT issues the notice to proceed to the Kiewit Massman Traylor design-build team |
| October 2, 2026 | Groundbreaking; construction expected to take five years |
| January 2027, projected | Start of a separate project widening I-10 in Baldwin County |
| Late 2031, projected | New bridge and Phase One open; tolling begins |
Phase One builds a new six-lane cable-stayed bridge over the Mobile River and restripes the existing Bayway to carry three lanes in each direction. About one mile of the Bayway will be rebuilt to connect to the new bridge. A brand-new Bayway structure is a Phase Two item, to be built as more funding becomes available, with future toll revenue helping pay for it.
The widening project is the one closest to Spanish Fort's own exits. ALDOT's project record lists six-lane widening of I-10 from east of the Bayway at U.S. 98 to east of State Route 181 at the Malbis exit. It shows a projected January 2027 start, a cost of $42,540,924.06, and a traffic impact of "periodic lane closures or lane shifts." ALDOT points drivers to ALGO Traffic for live updates.
If you close on a Spanish Fort home this winter, you'll be commuting through those five construction years without paying a toll. The rates described above start once the bridge opens.
Quick Answers
Is anyone paying a toll on I-10 right now? No. ALDOT says no tolls will be collected during construction.
Does the $60 monthly pass ever go up? It's fixed for the first 10 years of tolling. After that, it follows the same annual formula as the other rates.
Can I use a toll transponder from another state? Yes. Interoperable transponders, including E-ZPass-compatible ones, will work at the $7.70 rate. An ALGOpass account gets the $3 rate.
These toll figures come from published state policy and are general information, not financial or legal advice. Please confirm the current rates and your own commute costs with the official sources before you make a decision.
