MACKINAW CITY, MI (AP) — Authorities say a bomb threat closed the bridge connecting Michigan’s two peninsulas for about three hours on Sunday afternoon.
The Mackinac Bridge Authority said law enforcement notified them of the threat. The bridge was closed in both directions around 2:15 p.m.
The Michigan State and Mackinaw City police investigated. The bridge authority says nothing was found after an “extensive search.” The bridge was reopened shortly after 5 p.m.
