Traveling up 87 between NY metro and the Adirondacks.
The pinch point is on 87 south of Albany.
So you think people will be taking the week off?
For what it's worth, I generally avoid the interchange between the NY Thruway and I-87 by taking I-787 and RT7.
So driving north on Sat and back Wed, 7/4 or north on 7/4 and back on Sun? If that's the case then I would opt for leaving early on Sat morning. Traffic headed back towards NYC on Sunday is likely to be bad by mid-morning and continue until pretty late in the evening. Will have the people who took off the entire week, the latter part of the week, or just the weekend.
Even for people who only take part of the week off, I think most will want to be settled somewhere before dinner on the 4th. All depends on how they want to celebrate that evening.
Drove south from last Saturday. Started just south of Hartford. Far more traffic in CT and around NYC/NJ now that it's past Memorial Day. That's why I usually drive the longer way going thru PA on I-81 even for going to Boston from NC during the summer. Takes the same amount of time and no tolls.
