low clearance info

They should be in your Rand Mcnally Motor Carrier Atlas... In the front of the book.

 

Rand McNally won't list every single low-clearance, but it'll catch the major ones though you're on your own for secondary roads or many rural routes. That being said, I'd be rather less concerned about hitting a bridge in NM or TX than say, NY or PA.

 

...or Chicago!! Ugh!

 

Do doubt! You could parachute into Chicago blindfolded, hit the ground rolling, simultaneously throw a quarter, and hit a low clearance bridge. That same quarter would ricochet off 6 others before it gets pocketed by a bum.

To the OP. Try a google search for "low clearance - Texas - New Mexico" That worked for me a few weeks ago in Spokane, WA.
