A crash involving a tractor and a tractor trailer sent the semi truck plummeting off of Route 30 Bypass in Pennsylvania on Thursday afternoon. 

The crash happened at about 1:10 p.m. on the Route 30 Bypass above Old Mill Road in Sadsbury Township, Pennsylvania. 

According to ABC 6, authorities were called to the scene when a tractor trailer went off of the highway and landed on Old Mill road below. 

No information on injuries or the cause of the wreck has been released, but footage of the crash scene shows the semi truck nose down on the roadway below with the back end of the trailer resting on the highway overpass. A green tractor can also be seen damaged on the side of the roadway, with marks leading from the tractor to the balancing tractor trailer. 

The westbound lanes of the Route 30 bypass are closed at Airport Road until further notice.
