Andrew Craigie (1754–1819) is best known for serving as the first Apothecary General of the Continental Army during the American Revolution. The one-time owner of the Longfellow House–Washington's Headquarters National Historic Site, Craigie developed much of East Cambridge, Massachusetts and was responsible for the construction of the Canal Bridge connecting East Cambridge and Boston, which later became known as the Craigie Bridge and later was rebuilt as the Charles River Dam Bridge, but which is still also referred to as Craigie's Bridge.

The Charles River Dam Bridge, officially the Craigie Bridge, also called Craigie's Bridge or the Canal Bridge, is a six-lane bascule bridge across the Charles River in the West End neighborhood of Boston. The bridge, maintained by the Massachusetts Department of Conservation and Recreation, carries Massachusetts Route 28 next to the Green Line's Lechmere Viaduct. The Museum of Science is located on the dam and nearby piers. Charles River Dam Road connects Leverett Circle in the West End to East Cambridge, but most of the road is fixed, and the asymmetrically sited drawbridge is a short span entirely on the Boston side of the river.
