The Mackinac Bridge, a 5-mile-long suspension bridge connecting Michigan's Upper and Lower peninsulas, has been closed due to hazardous weather conditions in the Straits area. Strong winds, snow, sleet, and freezing rain have created whiteout conditions, making the bridge impassable. Bridge cameras show blank images as the bridge disappears behind the blowing snow.

Why it matters

The Mackinac Bridge is a vital transportation link between the two halves of Michigan, and its closure can have significant impacts on travel and commerce in the region. Whiteout conditions pose a serious safety risk to drivers, making it necessary to shut down the bridge until the weather improves.

The details

The Mackinac Bridge Authority announced the closure on Wednesday morning due to the current weather conditions. The National Weather Service reported wind gusts of up to 44 mph in the Straits area, along with a mix of snow, sleet, and freezing rain. Bridge cameras that normally show five different angles of the bridge are now displaying blank images as the structure disappears behind the blowing snow. Motorists approaching the bridge are instructed to reduce their speed to 20 mph and prepare to stop, with bridge personnel stationed at both ends to provide instructions.

  • The Mackinac Bridge was closed on Wednesday, February 18, 2026 due to the severe weather conditions.
