All the time. NC once routed me to a bridge to get back on 40. Well I get there and the bridge is actually torn out, like gone, not there. They were rebuilding it.
Called the state and got an alternate route. Luckily I saw the bridge was missing and the road closed before I made the turn. One time Missouri routed my 65 ton load to a 18 ton bridge. It was Saturday before I found that one. Called the troopers, they called someone at the state. They helped be back out and turn around and gave me directions on how to get around it. I would have probably just took my chances, but that bridge legitimately looked like 18 tons was the max.
Pulled a 100 ft long, 14 wide pedestrian bridge on a stretch flat. 2 pilot cars. In Illinois, they routed me down a 2 lane parallel to i57. Came to an old bridge, no shoulder with poles on the end. Half the bridge had been torn down. If it were still 2 lane, I would center it, if it didn’t have the poles, a flat would allow the load to ride over the walls. I called HP. A trooper came out, verified that I was on route. We had to back 2 miles and the state issued another route. I thanked him. If I need HP, I will call without hesitation. Thing is, be absolutely sure that you did your homework.
