Downtown Sun Prairie Closed Today After Fatal Gas Explosion

A large swath of downtown Sun Prairie remained closed this morning in the wake of a gas leak explosion Tuesday evening that leveled a downtown Sun Prairie bar, caused a massive fire at a pizza restaurant, killed a firefighter and critically injured another. A police officer, three firefighters, and seven civilians also were injured.

WE Energies spokeswoman Amy Jahns said workers for a contractor apparently punctured a 4-inch natural gas main, sending gas leaking into a building ahead of the explosion. All 12 gas lines in the area were shut off by about 9:30pm. Just after 10pm Tuesday, firefighters were still putting out a blaze that began after a gas leak rupture at about 6:20pm that led to an explosion about 40 minutes later in the 100 block of West Main Street in downtown Sun Prairie. Sun Prairie Police Lt. Kevin Konopacki said an evacuation began after the gas leak was reported, and the time between the gas leak and the explosion likely prevented more injuries.
