Did that years ago, heading from Bayville to Boothbay. Never again, at least not during hours when there is much traffic!!! Any local alternate route is still problematic for you. My suggestion is that you leave home around midnight on Sunday to avoid the traffic. By around 5 AM you should be near New London, where you can pick up 395 (just to the West of New London) to 90 to 495 and then back to 95, avoiding Hartford, Worcester, Providence and Boston. Have fun.
