Bath, ME to St. Michaels, MD: A 600-Mile Coastal Road Trip Guide

Leaving Bath, Maine (pop. 8,500) at the head of the Kennebec River, you begin a 600-mile southward journey to St. Michaels, Maryland on the Eastern Shore. The iron bridge crossing the Kennebec in Bath dates to 1927 and stands as one of the oldest continuous truss bridges in New England—a fitting start for a route steeped in maritime history.

Your primary roads will be I-95 South, I-295, I-95, and I-95/US 1 until the New Jersey Turnpike, then US 50 and US 301/MD 835. Expect 9 to 11 hours of driving without stops, but plan for at least 10–12 hours with breaks. How to find the best stops and hidden gems between cities is key to making this drive memorable.

The first leg from Bath to Boston hugs the coast via I-95 and offers glimpses of the Atlantic through patches of pine and granite. You will see the transition from Maine's rocky shores to Massachusetts' sandy beaches.
