The truck overturned sometime before 4 p.m. on Dec. 12, according to traffic advisories.

All of the southbound lanes of the turnpike are closed just after interchange four for Route 73 in Mount Laurel Township.

SkyForce10 was over the scene just before 5 p.m. where a truck with a green cab and a white trailer could be seen laying on its side and blocking all of the lanes.

It appeared as though at least three other cars had damage in connection to this crash.

Traffic looks like it is backed up for over one mile on the southbound side of the highway.

No word yet on what caused the truck to overturn or if anyone was hurt.
