Rand McNally Atlas

in the front of the atlas it should also list all low clearance locations by state and all restricted routes. The STAA authorized routes thing I always have to ask what that means cause I always forget but then again I run a reefer or dry box on the road not oversize stuff

 

Surface Transportation Act.......yes, you are ok on them !!

 

Not always. You can't trust what Rand McNally says. I know of at least one bridge in Pa it calls 12'6" and it's really 11'6". I've been trying to get them to change that for three years and every year it's the same. Obviously it's not on a main route, but they CAN be wrong...

 

Look at the chart called State Access Policies. That states what each state allows you off the designated (orange) network. It doesn't guarantee no low underpasses, tho.... Just that you'll be legal within that many miles off the network. You should also double check the restricted routes/low underpass locations in the state breakdown section. The exception is if you are going to a shipper or receiver. In that case, you are allowed to take the most direct route.
