A tractor trailer accident slowed traffic on Interstate 78 in northern Berks County for much of the day Wednesday.

The truck rolled onto its side in a grassy area off the eastbound lanes of I-78 at mile-marker 16.1, near the Midway interchange, in Bethel Township around noon Wednesday.

The trailer collapsed in a ditch.

The truck's driver reportedly suffered an abdominal injury and was taken to the hospital.

One lane of I-78 East was blocked by emergency vehicles, but both lanes had to be closed when it came time for crews to remove the wreckage.
