Routing through towns with low bridges

I hope that someone can offer me some advice on how to get the information that I am lacking.

I deliver to stores which are commonly in non-truck friendly towns, quite often in spots in the northeast where people otherwise wouldn't go in with anything bigger than a straight truck. I can get good directions for most of my stops, but I have a few where I keep running into low bridges and truck restricted routes. Last one had me sitting in the middle of the road, where there was no way I could safely back up the mile to the last intersection, with a bridge in front of me that I could only clear by less than an inch after I dumped my airbags.

The way I route isn't really out of line at all, or at least I think it isn't, although I will admit that I am totally self taught on how to do it. I will pull up directions for the major roads on the GPS and double check them with the atlas, but I stop using the GPS when I get into local areas. I pull up directions on the Qualcomm, double checking them on a map (including clearances and restrictions), and call the shipper/receiver if there is any doubt about it being a good route. 99% of the time that will easily put me right at their front door and I can follow the same route out back to the interstate.

Problem comes when there are no directions in the Qualcomm and the shippers directioins are worthless, or even worse route me under a low bridge or expect me to make turns impossible in a sleeper cab with a 53' trailer. I do my best to stick to what I see mapped as truck routes, but I have encountered several low bridges on these routes, which makes no sense to me.

So, how do you find a safe path through small towns in the northeast when no directions are available and the low clearances aren't listed in the atlas?

 

My question is about the times when the shipper/receiver is of no help. That usually works, but my question is about the times when it doesn't.

Never thought to call the police, but it does make sense. I only know how to get to me receiver in Norwalk, CT because of the cop I flagged down and got an escort from. Receiver tried to send me through a residential neighborhood, including a turn that was impossible in my truck.

 

Wouldn't get me the same sort of screwed up directions, with no note of low bridges, that I'd get from my GPS or by looking at a map?

My problem is not really finding a route to the location. It's more in how to figure out where these low bridges not listed in an atlas and not noticed by the shipper/receivers driving in their four wheelers, so that I can route around them.
