WAUWATOSA, Wis. (AP) - More than 30 vehicles piled up on an icy highway in Milwaukee County.
Two trucks, two buses and other vehicles were involved in the crash on Highway 45 in Wauwatosa about 10:30 p.m. Monday.
The sheriff's department says only one person was injured. The injuries aren't serious.
A bus carrying about 45 students and staff from UW-Oshkosh was involved in the crash. It was returning from a Brewers game.
The university worked with authorities to get a backup bus to Wauwatosa to bring the students home overnight.
A return to freezing temperatures made the roads slick and had sheriff's deputies responding to 43 crashes in Milwaukee County between 10 p.m. Monday and 2 a.m. Tuesday.
