(KMOV) – The victim has been identified in a rollover wreck on Highway 40 in St. Charles County Wednesday morning.
The wreck happened on eastbound Highway 40 just west of the Daniel Boone Bridge around 7 a.m.
Officials say Brendan R. Stieben, 20, failed to slow down for congested traffic and swerved off of the road.
The front of his vehicle struck a concrete barrier and overturned several times. Stieben was partially ejected from the vehicle and became trapped.
He sustained serious injuries and was taken to a nearby hospital.
All eastbound lanes of Highway 40 were shut down while emergency crews responded to the scene. The highway was back open by 10 a.m.
