I don't know the volume of traffic that travels on I-287 prior to the Tappan Zee and after but it has to be huge - I've traveled it to and from Florida annually and many many other times and I-287 is always under repair and once you get past the area you wonder if the trailer is still in one piece, I have had mirror's, pictures etc. fall off the walls of our travel trailer. Humpty Dumpty is an accurate description of how you feel once you get on Garden State or NJ Turnpike which is another huge construction zone, but at least they have the traffic moving in that area. With the volume of traffic the highways just don't last a long period of time. Plus the NE winter weather doesn' help, frost heaves etc.
I must be immune to the traffic after all this time - my prayer is that it just keeps moving no matter how heavy it is. I can deal with busy, heavy, and all the words that go along with it, it's the stuck and stopped I have a problem with. We always try to avoid peak times. Most years we leave RI on a Saturday Morning around 5AM and get to the garden state around 8 - 9 and miss the NY work day traffic. Last year we did Rt-301 (DelMarVa) to avoid Baltimore/DC I-95 and it wasn't bad just alot of stop lights in
the beginning. I would definately do it again.
