Emergency responders survey the scene at a fatal accident on westbound Interstate 70 Tuesday.

A 46-year-old Topeka man was killed Tuesday afternoon after seeking refuge from a rain storm under a bridge on westbound Interstate 70 near Bonner Springs.

Ronald Howard had legally parked his motorcycle under a bridge near mile marker 222 about 2:20 p.m. when a 1992 Mercury driven by a 33-year-old Lawrence man hydroplaned, striking Howard and another motorcyclist, Mary Brauner, 48, Topeka, before skidding into the median.

Another vehicle stopped to assist the victims and was hit by a hydroplaning 2004 Chevrolet Trailblazer, driven by a 44-year-old Lawrence woman, causing the parked car to hit the two victims.

Howard was taken to Kansas University Hospital, where he later died.

A Kansas Turnpike Authority dispatcher said Brauner was transported to Kansas University Hospital, but a nursing supervisor on Tuesday night was unable to confirm her presence or condition.

Traffic was backed up for about half an hour after the accident as emergency crews responded to the accident.
