OZAUKEE COUNTY -- A crash involving a semi-truck closed the southbound lanes of I-43 in Ozaukee County for several hours on Thursday night.
The crash happened on I-43 southbound and Lakefield Road just before 9 p.m.
According to the Grafton Fire Department, a semi-truck -- driven by a 49-year-old Sheboygan man -- lost control and jumped the guardrail on the Lakefield Bridge.
Fuel tanks on the truck were damaged -- causing nearly 200 gallons of diesel fuel to spread across both lanes of the highway.
The freeway reopened roughly three hours later. No injuries were reported.
The crash is under investigation by the Ozaukee County Sheriff's Office.
