We ran into a driver who was picking up in Buffalo NY. He said to us that he had to go around several blocks due to 12'6" bridge clearance. I informed him that NY caculates bridge height from center of hub which would make the actual height 13'6". He argued with me and since NY is no longer on our map, it wasn't worth arguing. I tried looking on NYDOT web sight but couldn't find where the information was. Oh by the way they had been driving for 3 months and were from NY. any advice on what is correct and were i can find the info would be appreciated
