TOWN OF NEWARK, Wis. -

Highway 81 west of Beloit was shut down following a fatal traffic crash involving a semitrailer carrying liquid fertilizer, according to a release.

The two-vehicle crash happened near Kauffman’s Country Store at 9550 West Highway 81 around 2:10 p.m., officials said.

A Pontiac operated by Barbara J. McConnell, 71, of Beloit, was stopped in traffic facing east and waiting to turn into a private driveway, according to the release. The semitrailer, operated by Willard T. Trewyn, 75, of Janesville, was heading east and was unable to avoid hitting the Pontiac stopped in traffic.

The semitrailer clipped the right rear corner of the Pontiac, lost control, rolled over and stopped in the south ditch of Highway 81, investigators said.

Trewyn was pinned inside the cab of the semitrailer and had to be extricated by emergency personnel, according to the release. Trewyn was pronounced dead at the scene.

McConnell and her two passengers did not suffer any injuries in the crash, deputies said.

Officials estimated 200-300 gallons of liquid fertilizer was spilled, but there is no health or safety risk to the public. The Department of Agriculture and the Wisconsin Department of Natural Resources were notified of the spill.

As of 9:30 p.m. Wednesday, Highway 81 was still closed.
