OK what is the best route from Salem MA to Plymouth MA with a BIG 5th wheel? Is it better to go the outer belt (I-95) or through Boston (I-93)? Going to be going midweek.
95. You can't go through Boston because of the tunnel as stated above. You're only real route is going down 95/128. Should take about an hour and a half. Don't leave Salem before 10 a.m. and you shouldn't have any issues.
