First responders are at the location of a fatal flatbed semi rollover crash.

The accident occurred in the westbound lanes on the Creek Turnpike near Aspen in Broken Arrow. Those westbound lanes are closed at this time. Tulsa Fire has been requested to come assist with this crash.

Police say the flatbed semi appears to have gone off the road to the left before rolling over, though they say they do have any witnesses to actually crash at this time.

This is a developing story.
