Bangor to Calais on Maine Route 9 ?

If you take 395 from Bangor to holden, you will bypass in town traffic, and there is an Irving station/circle k on 1a in holden with very good access for large rigs. Continue east on 1a for a couple miles then turn left on 46, it is only 5 miles or so over to rt 9 and you will have bypassed almost all of the 35mph and 40 mph zones through brewer and Eddington. There is a Walmart in brewer not far from 395 if you need any supplies or overnite parking.
