Temperatures bouncing above and below freezing over the next few days could create hazardous fog and icy roadways for travelers, Dane County Emergency Management officials said Tuesday.
The warning follows a 29-vehicle crash Monday morning on Highway 18/151 that killed one woman and injured several others in the town of Verona. Foggy conditions and speed factored into the fatal crash, the Dane County Sheriff's Office said.
The Dane County Medical Examiner's Office on Tuesday identified the woman killed in the crash as Catherine M. Hoelzel, 53, of Blanchardville.
The Department of Emergency Management warned that a melting and freezing cycle forecast for the next five days could produce hazardous conditions for motorists.
"Drivers must exercise great caution when maintaining control of their vehicle because road conditions can change with the crest of a hill or the surrounding ground cover," the department said in a statement.
Drivers are urged to slow down when traveling through fog and provide additional stopping distance from vehicles in front of them.
The county plans to make sure roads are able to properly drain water produced by melting snow.
Due to foggy conditions, more than 100 vehicles were involved in several crashes on Jan. 7, 2008 along a stretch of Interstate 39/90 that sent more than 50 people to the hospital, according to the emergency management department.
