Mackinac Island remains open as Mackinac Bridge closure affects mainland travel
Mackinac Island is still open to visitors today, but travelers heading to the area should be aware of a significant transportation disruption involving the Mackinac Bridge.
The Mackinac Bridge is closed to traffic in both directions following an emergency incident early Wednesday, September 23. Michigan transportation officials reported the closure during the early morning hours, and there was no immediate estimated reopening time.
The closure is important for travelers because the bridge connects Michigan’s Lower and Upper Peninsulas. However, Mackinac Island itself is not connected to the bridge.
Is Mackinac Island Closed Today?
No. Mackinac Island is not closed because of the Mackinac Bridge incident.
According to the Mackinac Island Tourism Bureau, the island can be reached by ferry, small plane or private boat. There is no bridge connecting the island directly to the mainland.
Mackinac Island State Park also remains open year-round, although individual attractions operate on seasonal schedules.
That means the bridge closure primarily affects people traveling by road between Michigan’s Lower and Upper Peninsulas rather than visitors already on Mackinac Island.
How the Mackinac Bridge Closure Affects Mackinac Island Travel
Visitors driving toward Mackinac Island should pay close attention to their route.
People normally reach Mackinac Island from ferry terminals in Mackinaw City or St. Ignace. The Mackinac Island Tourism Bureau lists ferry service as a primary way to reach the island.
Because the bridge is currently closed, drivers who need to cross between the two peninsulas cannot use the Mackinac Bridge until authorities reopen it.
Travelers should therefore check the latest bridge conditions before beginning a road trip and allow additional time if their plans require crossing the Straits of Mackinac.
Mackinac Bridge Incident: What Is Known
The Mackinac Bridge closure began during the early morning hours of September 23. Michigan Department of Transportation information initially described the situation as an emergency incident, while later reporting indicated that a crash was involved.
Authorities have been managing the scene and investigating the incident. Because details can change as the investigation develops, travelers should rely on current information from the Michigan Department of Transportation, Mackinac Bridge Authority and local authorities rather than unverified social-media reports.
The Mackinac Bridge Authority’s official conditions page showed the bridge closed during the morning. Earlier, the authority had also reported elevated winds in the Straits area.
Can You Still Visit Mackinac Island?
Yes. Mackinac Island remains in its main visitor season in late September.
The Mackinac Island Tourism Bureau says the primary visitor season generally runs through October, with fall bringing cooler temperatures, changing foliage and fewer crowds.
The island’s 2026 seasonal information also shows ferry operators and numerous businesses continuing operations during September and October.
Several attractions continue operating during this period. For example, Fort Mackinac is scheduled to remain open from 9:30 a.m. to 5 p.m. through October 4, with last admission at 4 p.m.
What Visitors Should Do Before Traveling
If Mackinac Island is part of your travel plans today, consider checking these items before leaving:
- Mackinac Bridge status: Confirm whether the bridge has reopened before driving toward the Straits.
- Ferry schedules: Check directly with your ferry operator because schedules can change with weather and operating conditions.
- Road conditions: Allow extra travel time if your route is affected by the bridge closure.
- Attraction hours: September and October have different operating hours from the summer season.
- Weather: Fall weather around the Great Lakes can change quickly, so travelers should plan accordingly.
The Mackinac Bridge Authority also provides live bridge information and recommends that motorists monitor official updates during closures.
Mackinac Island Remains a Fall Destination
Despite today’s transportation disruption, Mackinac Island continues its transition into the fall season.
The island offers biking, hiking, horse-drawn carriage rides, historic attractions, shopping and dining. The Tourism Bureau’s current event listings include activities continuing through September and into October.
The island’s fall calendar also includes the Fall Fudge Festival scheduled for October 2–3, 2026, while several lodging and tourism businesses remain open later into October.
Bottom Line for Mackinac Island Visitors Today
The key distinction for travelers is that the Mackinac Bridge closure does not mean Mackinac Island is closed. The island remains open, but people traveling by car need to account for the current bridge disruption when planning their route to a ferry terminal.
Because the incident is still developing, conditions and reopening information can change. Anyone traveling through the Mackinac area today should check the latest official bridge and ferry information immediately before departure.
