State police have released more information about a fatal accident that closed Route 22 East in Lehigh County for several hours Monday evening.
The accident happened around 4:40 p.m. near mile marker 315 in Upper Macungie Township, near the Interstate 78 split.
According to police, a pickup truck was traveling east on Route 22 in the right lane, and a tractor trailer was parked on the right shoulder of Route 22.
For an unknown reason, the pickup truck left the road and hit the left rear of the tractor trailer, police said.
