Mackinac Bridge was just closed for 30 hours. That’s a new record. Officials are optimistic that the bridge is now cleared of ice and won’t need to close again.

The Mackinac Bridge has closed again because of ice falling off the suspension bridge that connects both of Michigan's peninsulas via Interstate 75. Mackinaw City Police Department issued a notice to the public at 9 a.m. Tuesday, informing motorists of the conditions reported by the Mackinac Bridge Authority. A reopening time was not known.
