Not a lot of time to mess around with alternate routes. Do I-95. There are a few alternatives that will avoid the big areas. DO NOT go down the Cross Bronx to the GWB. From Worcester, take the Pike to I-84 to I-684 and the Tappan Zee, then down the Garden State Parkway to I-95/I-295 to the Delaware Mem. Bridge. You can grab US-301 just on the other side of the Delaware and run that down to Fredricksburg VA area to avoid Baltimore/Wash DC and pick up I-95 in Fredricksburg or Richmond.
Pick your time to go down the GSP (Sunday morning was a breeze) and you won't have any issues.
