A crash in the northbound lanes of the Northeast Extension near Quakertown snarled traffic Tuesday morning.
A spokeswoman for the Pennsylvania Turnpike Commission said a contractor was working on the road removing a traffic pattern between milepost A53 and A56.7 when another vehicle struck the truck.
No injuries were reported in the crash, but northbound traffic was at a standstill shortly after 7 a.m. The involved trucks blocked the right lane and right shoulder, and debris blocked the left lane, the spokeswoman said. One truck also had an active fuel leak on the road.
The Turnpike Commission advised northbound drivers in the area to exit I-476 at Quakertown (Exit 44) and take a different route to avoid delays.
