This historic corridor, once part of the Boston Post Road, connects colonial settlements and modern metropolises.

It also crosses the Piscataqua River Bridge, a tied-arch bridge that opened in 1972 and is one of the longest in New England.

I-95 is well-maintained with rest areas roughly every 30 miles. For family suitability, consider the Mystic Aquarium in Connecticut or the Portland Children's Museum. Pet-friendly hotels are abundant, especially along the Maine Turnpike.
