The Mackinac Bridge in Michigan has been closed due to hazardous ice conditions, with falling ice chunks posing a threat to drivers. This is the second time the bridge has been closed this week, with previous closures due to high winds and poor visibility. The Mackinac Bridge Authority is monitoring the situation and will provide updates on when the bridge may reopen.

Why it matters

The Mackinac Bridge is a critical transportation link between Michigan's Upper and Lower Peninsulas, and its closure can have significant impacts on travel and commerce in the region. Falling ice is a recurring issue for the bridge, and authorities must balance public safety with the need to keep the bridge open as much as possible.

The details

The Mackinac Bridge Authority closed the 5-mile-long bridge on Thursday, February 19th, due to the potential of falling ice. Fallen ice chunks have caused damage to vehicles in the past, and with the bridge's height of 100 feet, there is a risk of injury or even fatality to drivers. On average, falling ice closures last around 5 hours and 54 minutes.

  • The Mackinac Bridge was closed on Thursday, February 19th, 2026 at 9:55 a.m. due to hazardous ice conditions.
  • On Wednesday, February 18th, 2026, the bridge was closed for over two hours due to high winds and poor visibility.
