I will soon be starting a six month tour of the US and Canada, and will be travelling in a Winnebago Sunstar which is quite big. While I will be on the major routes quite a lot, I also intend to take it off the beaten track. So I’m a little worried about bridges or underpasses with width and weight restrictions. I have a low clearance POI database, but can’t find anything for narrow bridges or bridges with weight limits. If anyone knows of any (in the US or Canada), I would be most grateful if you could post the coordinates here. Many thanks.
