Mackinac Bridge Closed for Second Time in Two Days After Falling Ice From Suspension Cables Creates Dangerous Driving Conditions in Michigan
MICHIGAN — The Mackinac Bridge was shut down again late Thursday night after officials warned that ice falling from the suspension cables posed a serious threat to drivers, marking the second closure in as many days.
The latest shutdown was announced around 9:23 p.m. Eastern on February 20, 2026, as freezing conditions continued to impact the structure and surrounding roadway.
Second Closure Issued Late Thursday Night
Officials confirmed the bridge was closed after renewed reports of ice shedding from the massive suspension cables. A nighttime camera view showed slick pavement and wintry buildup along the bridge deck as traffic was halted.
This was not a routine traffic pause. The decision was made out of caution after falling ice created unpredictable and potentially life-threatening conditions for vehicles traveling across the span.
Why Falling Ice Forces Immediate Action
Large suspension bridges like the Mackinac Bridge are especially vulnerable during winter storms. Ice can accumulate along cables, towers, and other elevated components. When temperatures fluctuate or winds increase, chunks of ice can suddenly break free and fall onto the roadway below.
Even small pieces of falling ice can damage vehicles, while larger sheets pose significant danger to drivers. Because there is no way to fully control when ice will drop, closures are often the safest and fastest response.
Travel Disruptions Across the Straits
The Mackinac Bridge is a critical link between Michigan’s Upper and Lower Peninsulas. When it shuts down, there are no simple alternate routes, leading to significant travel disruptions for commuters, commercial drivers, and long-distance travelers.
Motorists were advised to delay trips and monitor conditions before attempting to cross once the bridge reopens.
What Happens Next
Reopening decisions depend on changing weather conditions and whether ice continues to fall from the cables. Crews monitor wind, temperature, and roadway safety before allowing traffic to resume.
Even after reopening, drivers may experience slower traffic or temporary restrictions while crews ensure conditions are safe.
