First time traveling from NJ to Maine

Adding an odd but of information, the Pallisades Parkway is fine for 13' all the way to the Tappan Zee as well.

I took that to the rest of what everyone is saying.

You're in for a treat in Maine. One if the best spots in the USA. Enjoy!

North part of the GSP has some bridges with under 13' clearance at the sides, you have to be VERY careful about what lane your in. As said, do NOT try the Merrit - its a no-go.

Take the GSP to I-287 North, follow either over the Tapanzee (now renamed) to 84 or my preference is to take the NYS Thruway up to I-90 East towards Boston, pick up 495 AROUND Boston to 95 North. There is a Cabelas off 495 in Mass that you can boondock in. Used to even have a dump station but we never used it.

Basically seconding Lumpty's post.

We find 84 through CT to be a bear, always hit traffic. You won't enjoy 95 traveling north of NYC towards Boston.

After numerous trips to Maine, we prefer to drive a touch further and avoid the traffic delays, rough roads and aggravation that the other routes always provided to us.

We are at GSP exit 105. RVs are OK the full length of the GSP. No trucks allowed north of exit 105. When we go to Maine, we take the GSP to I287 over the Tappan Zee Bridge to I684 to I84 to I90 to I495 to I95 into Maine.

Between about exit 135 and 150 there are some arched bridges with low sections on the shoulder of the GSP, although I don't think any are less than 13ft even at the shoulder. No issue with height if you stay one lane from the right or left in that section. These bridge heights are well signed.

Thank you Lumpty for info on Merritt. What about the northern part of Garden State Parkway?

Ctrl DOT says "Vehicles over 8 feet (2.4 m) in height, weighing more than 8,000 pounds (3,600 kg), towing a trailer, or containing more than four wheels are not allowed on the parkway." So maybe you shouldn't go that way.

Do NOT take the Merritt! Major height restrictions, a tunnel and narrow lanes and no sight distance. Anything larger than a car, pickup or SUV is illegal.

As alternate routes, 287 over the Tappan Zee to 684 to 84, or a longer but never any traffic way is the Thruway north towards Albany then pick up the Mass Pike extension. 60 miles further to the Mass Pike - 84 interchange but frequently less travel time.
