A street in Superior, Wisconsin, has been closed down after authorities received a "credible" bomb threat.
The announcement was made by Mayor Jim Payne, who said the threat relates to the new fire hall on Tower Avenue.
Superior Police Department confirmed it is "dealing with a possible homemade explosive device on the sidewalk just north of the Superior Fire Department Headquarters on Tower Ave."
Tower Avenue has been closed in both directions as a result of the threat, Paine posted at around 10 a.m.
"Please stay away from this site and use an alternative route," Paine wrote.
"The State Bomb squad is en route and will clear the device in a few hours. Scary start to October, I know, but we should be back to regular business soon."
The threat comes after a challenging week for Superior, which has been dealing with flooding problems in the city and wider Douglas County, after the nearby Nemadji River rose more than six feet in 24 hours.
