TOLEDO, Ohio (WTVN) - The State Highway Patrol reports accidents involving several tractor-trailers shut down the Ohio Turnpike in both directions midway between Toledo and Cleveland on Wednesday.

"It's a 2-mile long scene approximately 50 cars are involved," said Highway Patrol Sgt. Vincent Shirey.

Three people were killed in the pile-up. A trooper was also hurt when he was pinned between two vehicles at the scene.

"He is conscious. He sustained injuries in the abdomen and lower extremities," Shirey said.

Emergency crews had to wait several hours to take Tpr. Andrew B. Clouser to a Toledo hospital. He is 29 years old and has been on the Patrol for a little over a year.

The crash happened around 1:25 p.m., shutting down all lanes of the Ohio Turnpike just south of Sandusky.

5 accident re-constructionists and 20 state troopers have been going vehicle-to-vehicle checking on stranded motorists.

The Turnpike says another pileup has the westbound lanes of the toll road blocked in Lorain County. 30 more vehicles were reported in a pile-up on I-480 near Cleveland.

A big dose of heavy, blowing snow is hitting much of northern Ohio.

"Weather has been a problem in the northern part of the state this afternoon," said Shirey. Along with the trooper hurt on the turnpike, four other Highway Patrol cruisers have been struck on northern Ohio highways.

Many counties along the top edge of the state from the Indiana state line to Sandusky are telling drivers to stay off the roads unless they are emergency or essential personnel.

The Ohio State Highway Patrol says at least four other troopers were struck, all while in their cruisers, around northern Ohio on Wednesday.
