@gedeonm@mastodon.social they need to be at least two semi truck lengths away. With a turnaround. A common problem with can opener bridges.: The trucker knows the bridge is 13.5, and his trailer height is 13. But the bridge is actually over a dip. 30 feet back from the bridge, the rear of that trailer is relatively over 14 feet relative to the over pass. The trailer wedges as the cab reaches the other side because the rear of the truck is higher. Roof of trailer is peeled off
