VIDEO:Some 7 hours and 45 minutes after it closed down, Highway 53 just south of Eau Claire has reopened.
Crews spent the majority of the day cleaning up after a truck hauling 26,000 pounds of ammonium nitrate, 300 gallons of diesel and an unknown amount of dynamite tipped over.
"When these materials are mixed together, they can be ignited and have some explosive properties to them and that is why we took all the steps that we could to minimize and mitigate the incident," said Allyn Bertrang, deputy chief of the Eau Claire Fire Department.
The incident also caused traffic to back up near Golf Road and Highway 93.
