The Ohio State Highway Patrol says a truck crashed onto I-475 south from Nebraska Ave. in Springfield Township around 10:30 p.m. on Saturday.
Nebraska dead-ends at the expressway just east of McCord and picks up on the other side.
One person had to be taken to the hospital although their condition is unknown at this time.
A neighbor who lives on Nebraska Avenue between I-475 and McCord says cars frequently speed down this stretch of Nebraska.
A mound at the end of the street is supposed to act as a barrier to the highway from the dead-end street.
The same neighbor says multiple cars have crashed into the mound or driven over it onto the highway since he has lived there.
Debris from numerous cars can be seen in the area where Saturday's accident occurred.
The accident slowed traffic on the expressway as crews worked to clean up the mess.
