For an I-75 road trip between Michigan’s Lower and Upper Peninsulas, the cost to cross the Mackinac Bridge is simple for most travelers: $4 for a standard two-axle passenger vehicle. The price changes once you drive a larger vehicle, tow a trailer, use a motor home, or pay by credit or debit card at the booth.
The bridge toll is charged one way each time you cross. Northbound drivers pay when entering the Upper Peninsula, and southbound drivers pay when heading back toward Mackinaw City. The amount is low for a normal car, but trailers and larger rigs can raise the total fast because the bridge prices those vehicles by axle.
What The Toll Costs Right Now
The Mackinac Bridge toll is $2 per axle for passenger vehicles, with a normal two-axle car charged $4 per crossing. Larger vehicles that do not meet the passenger-vehicle category pay $5 per axle.
The passenger rate covers the vehicles most road-trippers use: passenger cars, vans, motorcycles, station wagons, SUVs, pickup trucks, and school buses. A standard SUV or pickup with two axles pays the same $4 base toll as a sedan.
Larger setups need a bit more care. A motor home, tractor trailer, commercial bus, step van, cube van, or similar vehicle falls into the “all others” category unless the Mackinac Bridge Authority classifies it another way at the booth.
Crossing The Mackinac Bridge: Current Tolls By Vehicle
Mackinac Bridge toll costs depend on vehicle class first, then axle count. The table below shows the common crossing situations a traveler is most likely to face.
| Vehicle Or Setup | How The Toll Is Priced | Typical Cost |
|---|---|---|
| Standard passenger car | $2 per axle, normal two-axle passenger rate | $4 |
| SUV or pickup truck | Passenger-vehicle rate when it fits the standard category | $4 |
| Motorcycle | Passenger-vehicle axle rate | $4 for a typical two-axle bike |
| Passenger van | Passenger rate if it is a two-axle, four-tire van not mainly used for cargo | $4 |
| Passenger car towing a small trailer | Lead vehicle sets the rate; trailer axles are charged at the same passenger rate | Usually $2 per total axle |
| Motor home | All-others rate unless classified differently at the booth | $5 per axle |
| Tractor trailer or commercial rig | All-others rate by axle | $5 per axle |
For a simple example, a two-axle car pays $4. A three-axle passenger setup, such as a car towing a one-axle small trailer, is usually $6 because the passenger rate applies by total axle count.
The Mackinac Bridge Authority posts the live fare categories on its official Mackinac Bridge fare schedule, including the passenger-vehicle rate, the larger-vehicle axle rate, and the current payment rules.
How Do You Pay The Mackinac Bridge Toll?
Mackinac Bridge toll booths accept cash, credit and debit cards, Apple Pay, Google Pay, and MacPass. The authority lists cash, Apple Pay, Google Pay, and MacPass as faster booth transactions than credit or debit cards.
A 2.3% fee is applied to credit and debit card transactions. For a $4 passenger-vehicle toll, that works out to about $4.09 if the card fee applies at the booth.
MacPass is the bridge’s prepaid toll account system. MacPass makes the most sense for frequent crossings, repeat Upper Peninsula trips, or drivers who want a faster toll-lane routine without handling cash each time.
| Payment Method | Works At The Booth? | Good Fit |
|---|---|---|
| Cash | Yes | One-time drivers who want the posted toll with no booth card fee |
| Credit or debit card | Yes | Drivers who do not carry cash and accept the 2.3% card fee |
| Apple Pay | Yes | Drivers who want a faster mobile-wallet transaction |
| Google Pay | Yes | Drivers using Android mobile-wallet payment |
| MacPass | Yes | Frequent crossers and prepaid-account users |
| Commercial account setup | Varies by account | Businesses or fleets crossing often |
| Manual booth classification | Yes | Unusual, oversized, or unconventional vehicles |
What Changes The Price When You Tow A Trailer
Towing changes the Mackinac Bridge toll because the total axle count rises. The lead vehicle determines the rate class, and anything being towed is charged at the lead vehicle’s per-axle rate.
A passenger car towing a small trailer usually stays in the passenger-vehicle pricing system, so every axle in the setup is charged at $2. A pickup with two axles towing a two-axle camper would usually have four total axles, which points to an $8 crossing at the passenger rate.
Motor homes have a special rule. When a motor home tows an auto, the motor home is charged under its own vehicle class, while the towed auto is charged at the auto rate.
Tip: Count every axle touching the road before you reach the booth. That gives you a realistic toll estimate before the attendant classifies the vehicle.
Where To Stay Before Or After The Bridge
Mackinaw City is the easiest Lower Peninsula base before a northbound crossing, while St. Ignace works well after crossing into the Upper Peninsula. Staying near the bridge helps if you want an early drive, a sunset view, or a slower stop instead of pushing farther on I-75.
For most travelers, Mackinaw City has the broader mix of pre-bridge motels and waterfront stays, while St. Ignace is better if your next day starts in the Upper Peninsula. Compare nearby stays before locking in your route:
Simple Cost Verdict For Your Crossing
The right Mackinac Bridge toll estimate is $4 for a normal car, SUV, pickup, motorcycle, or passenger van. Budget more if you tow anything, drive a motor home, or bring a commercial-style vehicle.
- Most road trips: plan on $4 each time you cross.
- Passenger vehicle with trailer: count total axles and multiply by $2.
- Motor home or commercial vehicle: count axles and multiply by $5 unless the booth classifies it differently.
- Card payment: add the 2.3% fee to the booth total.
- Frequent crossings: consider MacPass so payment is prepaid and faster at the plaza.
A driver in a normal car can cross the Mackinac Bridge for less than the cost of most roadside snacks. The price only becomes a planning detail when you add axles, tow a camper, or use a larger vehicle class.
