An overturned tractor trailer slowed traffic on Route 422 in eastern Berks County.

The accident happened shortly before 3 p.m. Wednesday on 422 West at South Center Road in Exeter Township.

The truck was turning onto 422 when the trailer's load shifted, causing the truck to roll onto its side, police said.

No one was injured.

Westbound traffic was reduced to one lane while crews worked to upright the truck and haul it away.
