Why is the speed limit only 65 on this freeway (I95)?
It's only (about) 16 miles, end to end
It serves a heavy amount of tourist traffic
There's a toll booth about halfway through
It has some interesting interchanges in downtown Portsmouth
Judging by all these characteristics, we should be lucky it's 65.
If I-696 in Detroit can be 70, so can I-95 in NH.
The real reason is because most of the Northeast is against anything over 65.

Maine will go 75. Only Maine can handle above 65 in the northeast.

Because that's the law in New Hampshire.

Only north of Bangor where it turns into nothing but trees and the very occasional other car.
I think there are plenty of roads in the northeast that could qualify for at least 70.

Mass Pike west of the 84 split comes to mind, as do several sections of I-91, 93, and 89 in NH/VT. I'd even slap 75mph onto the northern sections of I-91.
I'd also put 65 on some two-lane roads like US-3 in the Connecticut Lakes region of northernmost New Hampshire, and other rural roads like ME-11.
I-91 north of White River Junction or even north of MA 2 or Brattleboro would certiantly qualify
Speed of traffic on the New England interstates is typically in the upper 70s. Vermont is an exception - too many cops. Mass Pike usually ends up in the low to mid 80s, so the speed limit could easily be increased without any safety issues.
95 in NH is fairly crowded, but it does have that nice high speed fastlane toll. Wish that was in more places.
Speaking from experience, the Vermont Interstates can adequately handle 70 MPH. 75 MPH might be a push, between the hills and the moose (especially the moose at night). I'd also keep I-89 near Montpelier at 65 MPH and through Burlington at 60 MPH. I-91 across the White River should probably remain 55 MPH.

moose at night are an advisory concern, as is fog and various other conditions I've encountered on the interstates of Vermont. In ideal conditions, I can do (and have done) 84-85mph safely - less than ideal, I've found situations (fog thick enough to hammer nails with) where 25 seemed to be awfully fast.

It took a long time for the North-East to go 65 when it the 65 interstate limit was first passed in the 80s. Some states like CT did not even implement that until the 90s.
