UPDATE: Semi driver responsible for I-41/US 45 north Tuesday crash ticketed

Updated: 1:16 p.m. July 18, 2018

WAUWATOSA, Wis. (CBS 58) -- The Milwaukee County Sheriff's Office has released more information on Tuesday's rollover crash that caused a full freeway closure.

The incident was reported around 4:20 p.m. when the semi rolled on I-41/US 45 north just south of North Avenue. 

The semi used compressed natural gas as fuel which was leaking and caused the closure of all nearby ramps and southbound lanes. 

During an investigation, deputies determined that when traffic slowed in front of the truck, the driver was unable to slow and hot the car in front of it causing a chain reaction. The semi veered to the left during the crash and hit the median wall crossing all lanes of traffic and flipping on its side.

The semi driver was treated for a minor arm injury and one of the other drivers was treated for back, neck and shoulder pain. 

The semi driver from Waukesha was ticketed for unreasonable speed truck following too closely.
