Kennebunkport to Provincetown: Ultimate Road Trip Guide

The route from Kennebunkport, Maine to Provincetown, Massachusetts spans roughly 140 miles, but the journey can take 5 to 7 hours depending on traffic and stops. Much of the coastal route follows US Route 1 and then Interstate 95 south, before cutting across the Cape Cod Canal on the Bourne Bridge. The most direct driving time is about 3.5 hours without stops, but the real draw lies in the detours. A notable local driving quirk: the Bourne and Sagamore bridges frequently back up, especially on summer weekends, making the rotary at the Sagamore Bridge a notorious bottleneck. For an immersive experience, plan a full day to explore the diverse ecosystems and cultural hubs along the way.
