Hannibal MO to Rochester NY to Saguenay Quebec Canada

Do yourself a favor when in Canada, it's the 401 east in Ontario which becomes the 40 in Quebec. AVOID AT ALL COSTS going through Montreal by taking the 30 EST/ EAST. There is a toll but it is only on the new bridge, I don't know what it would be for your rig but it was only $2 when I went with the car. Stay on the 30 until you see a sign for the 20 EST/EAST. 20 east to the 73 which takes you back over the St Laurence near Quebec City. 73 in Quebec will get you to the 40 north of the City.
Safe travels.
