Rising waters on the Baraboo River could force portions of Interstates 39 and 90/94 to shut down on Thursday.
The Department of Transportation has been monitoring water levels in Columbia County, in the area where the Interstates divide. If the river continues to rise, several sections could be shut down.
The areas currently at risk are northbound I-39-90-94 at WIS 60 near Lodi, eastbound I-90/94 at US 12, and southbound I-39 at US 51 near Portage.
Jan Klawitter at the state Emergency Operations Center says the DOT has been trying to use sand bags to keep the water off the roadway. But if water levels continue to climb, they will act to keep motorists safe.
Klawitter says officials are planning alternate routes, which will be released if a closure is needed.
Flooding has already closed hundreds of roads across the state.
