 Terminal 1 at Minneapolis-St. Paul International Airport is back open after an investigation into a suspicious item. Police shut down Highway 5 leading into the airport just after 5.30 p.m. after the item was found at the north end of the terminal. No one was allowed inside the terminal and the closure resulted in a huge backup along the road until everything reopened about 45 minutes later. Airport police have not released any details about the item or what made it suspicious.
