here is the number to a permitting co. that I use when hauling oversize loads. They can give you all the routing for oversize and they'll pull all the permits needed and fax them to you......
1-800-749-6019 they even gave me the routes I needed to take when I haul overheight loads.......

Make sure you check the load rate of your tow truck & trailer hitch, to be sure it can handle the weight. most hitchs are rated for 10,000 lbs you may be over that ? If you get stopped you will not move until you get a truck rated hi enough, along with all proper paper work. Do like they said above and get the permits.

and you have to be inspected at ever state,or DOt will make you park it........now understand I've pulled oversize loads with no permits and got lucky,hell,all the way from texas......but got real nervice to many times....there not real expensive........
