Just a reminder to know the height of your rig

Like one post already said, repaving changes the clearance but not the sign. SOP is to lay 2 inches asphalt each time a road is repaved, and the 3rd time, all the asphalt has to be grinded off before repaving. So the clearance can be 2-6 inches off, unless your going to put all your faith in DOT and contractors to follow SOPs and change signs each time.

I know for a fact that the clearance signs in our TxDot district indicate the clearance as being 3" lower than it actually measures on most bridges. A little buffer if you will. Our signs are definitely changed if there is a need to keep the clearance shown on signs plus at least some buffer. Most of our work under bridges consist of a mill and inlay which doesn't decrease the clearance in most cases.
