A Doolittle man was killed in a crash in St. Louis County Sunday morning.

According to a Missouri State Highway Patrol report, Teddy B. Bass, 56, of Doolittle was eastbound on the Interstate 44 ramp to Interstate 270 at 11:35 a.m. Sunday, when the 2007 Kenworth T600 he was driving traveled off the south edge of the road. Bass then allegedly over-corrected, causing the vehicle to travel off the north side of the road before striking a highway sign.

Bass was transported to Mercy Hospital by the Fenton Fire Protection District. He was pronounced dead at 12:34 p.m. by Dr. Dennis Kiethley.

The major crash investigation unit also responded to the scene.
