Concrete Barrier Protrusion

Question
State
Description Text	What is the maximum protrusion along a concrete median barrier that would be acceptable? We have some sections of median barrier wall that no longer line up with the light pole foundations. There is now a snag point where a vehicle sliding along the wall would hit. For some reason, I thought that 1" was allowable. Does it matter if the edge is beveled?

Response
Response (active)	Previously, MwRSF provided guidance noting that it was preferred to have the maximum lateral barrier misalignment limited to 1" or less. In addition, I believe that it would be preferred to utilize chamfered corners or edges to assist in mitigating vehicle snag on any exposed sharp edges. I have attached a pdf copy of a prior Pooled Fund Progress Report and Consulting Summary which contained this general guidance.
