Last night I was proceeding east on the pa turnpike when traffic came to a halt, both lanes. Turns out at the entrance to a construction zone the road was narrowing from 3 lanes to 2. Just past the entrance to the construction zone it went from 2 lanes to 1.
Why you ask? A 53ft trailer being hauled by United States Freightways decided to split itself in half and dump its contents all over the highway. What a mess.  It appeared though that no one was hurt.
