(KMZA)--A bicyclist was seriously injured late Sunday night after he was struck by a semi-tractor trailer on U.S. 36 Highway in Marshall County.

The Kansas Highway Patrol says 55-year-old Richard Kempher, of Omaha, Nebraska, was westbound in the driving lane when a westbound semi struck his bicycle around 11:30 about 8 miles east of K-148 Highway.

Kempher was transported by helicopter to Bryan Medical Center West in Lincoln with what the patrol described as disabling injuries.

The semi driver from South Charleston, Ohio, was not hurt.

The Patrol says Kempher was wearing a helmet, reflective vest, and had lights on a backpack and reflective lights on his bike.
