I designed large packaged systems that we had to design with the transport means in mind and where it was headed. The shipping department handled all the logistics with the truckers. Before a loaded truck left the shop, we had the driver up top with a tape measure and to also check maximum with and overall length. We noted these dimensions on the way-bill so that he was fully aware of his load size.
One time we had an oversize load hit a bridge (it was over height, width, length and weight). It was winter, so we had to watch the axle load limits on certain roads coming from Toronto to the Texas Gulf Coast. The driver decided to get off his designated route and visit a girlfriend and found a bridge he would not fit under. It cost his insurance and trucking company about $350,000 for repairs on the equipment in 1977. The trucking company said he would never drive again in North America.
So, measure your rig yourself and watch the low clearances.
