PLATTE COUNTY, Mo. — A deadly crash on northbound Interstate 29 just north of Platte City significantly backed up traffic while first responders and investigators worked the scene Wednesday morning.

The crash was reported around 7 a.m. The Missouri State Highway Patrol reports the driver of a commercial motor vehicle struck the rear of a semi.

The driver of the commercial motor vehicle was pronounced dead on the scene. She has been identified as 41-year-old Jill Buxton, of Kansas City, Missouri. She was wearing a seatbelt, according to MSHP.

The northbound lanes were closed for a few hours, but I-29 has completely reopened and traffic is moving normally again.

The driver of the semi was not reported to have injuries.
