An elderly man was killed in a single-vehicle crash on Lake Shore Drive, just east of Airport Road in Waco shortly after 3 p.m. Friday.

The cause of the crash was not immediately clear, but police said the victim was the driver. No passengers were in the vehicle nor were any other vehicles involved, Waco Police Sgt. Patrick Swanton said.

Westbound traffic from N 19th Street was being diverted, while first responders were on scene.

Authorities urged drivers to expect delays or seek alternative routes.

A Waco Police accident reconstruction team will investigate the crash to try to determine what happened.
