?What?s that scraping sound??
There is a bridge in Durham NC that is famous for destroying Trailers and tall vehicles, It has its own web page its called the 11 foot 8 bridge. They have placed warning lights that flash and all kind of signs warning people but they still crash.
Here are some crashes:
It had a covered entrance way that the school buses dumped off kids at.
My crew just finished installing the overhead lights and we watched the General contractor's men measure and put up the signs for overhead clearance.
The "going in" side of the covering was 11' 9", and so it was marked as such.
Because of the upward slope of the grade the "leaving out" side of the covering was only 11' 2".
I asked the GC, "won't it be better to mark both sides at the lower measurement????"
He thought I was crazy, and couldn't see the logic in my question.
The engineers need to be protecting the users from having to kae the decision if they gave enough clearance.
