MINNEAPOLIS (WCCO) – A portion of the southeast corner of the Minnesota State Fair cattle barn collapsed Tuesday evening.

Officials say the collapse occurred due to the weight of snow on the roof. Firefighters were on scene Tuesday night.

The part of the structure that collapsed was used to house State Fair trailers and other equipment, the St. Paul Fire Department said.

According to the State Fair website, the 117,450-square-foot cattle barn is nearly a century old. The brick structure can house 1,000 head of cattle.

In a statement, the Minnesota State Fair says the rest of the building remains structurally sound.
