TULSA - The driver of a flatbed semi rolled on Interstate 244 near Utica Avenue Wednesday morning, dumping near 20 tons of cinder blocks onto the highway and creating a major traffic snarl.
Lt. George Brown of the Oklahoma Highway Patrol tells KRMG the driver swerved to miss a metal ladder that someone had apparently lost from a vehicle.
When he swerved, his load shifted and the truck overturned.
Early in the incident, troopers say it will take hours to clean up the mess and get traffic flowing smoothly again.
The inside (left) lane remains open westbound, but the outside lanes are closed.
Drivers are urged to avoid the area if possible.
No one was hurt in the incident.
