Kennebunkport to New Bedford: Coastal Maine to Mass Road Trip

This 152-mile drive along US-1 and I-95 South, typically taking 2 hours and 45 minutes without traffic, shadows the historic route of whaling ships and coastal trade. The Kennebunkport River, where the first American shipyard launched in 1603, meets the Atlantic at Walker's Point, while New Bedford's harbor still echoes with the world's largest whaling fleet of the 19th century. The direct stretch of I-95 bypasses the ragged coastline, but savvy travelers will want to peel off onto Route 1A for lobster shacks and marsh views.
