The Charles River Dam Bridge, officially the Craigie Bridge[1] , also called Craigie's Bridge or the Canal Bridge, is a six-lane bascule bridge across the Charles River, connecting Leverett Circle in downtown Boston, to Monsignor O'Brien Highway in East Cambridge, Massachusetts. The bridge, maintained by the Massachusetts Department of Conservation and Recreation (DCR, formerly the MDC), carries Route 28 next to the Green Line's Lechmere Viaduct. The bridge is fully within Boston, with the city line to the north, at the center of the original river. The Museum of Science is located on the dam and nearby piers.
The original lock for the Charles River was just west of the Charles River Dam Bridge, but the lock services was relocated east to the Charles River Dam and incorporated as three parallel locks on the site of the old Warren Bridge.
The former lock at the Charles River Dam Bridge now allows water and small ships to flow freely. Taller ships require the opening of the drawbridge, operated by the Massachusetts State Police.
History
The first bridge on the site was known as the Canal Bridge, named after the Middlesex Canal which ran from the Mystic River to Lowell.[2] (It was not named after the short Lechmere Canal which is now near the Cambridge side of the bridge, but did not exist at the time.) As an investment, businessman Andrew Craigie purchased the largely undeveloped farmland on the Cambridge side around Lechmere Point from various owners (including Mary Lechmere and heirs) in preparation for building the bridge. The investors incorporated in 1807 with a charter to build a bridge from Leverett Street in the West End, Boston to the eastern end of Lechmere Point. One-third of shares were owned by the Middlesex Canal Corporation. [3]
The bridge opened in 1809, and came to be known as Craigie's Bridge. The construction of the bridge prompted the laying out of roads to the center of Cambridge (now Cambridge Street, running to Harvard Square) and Somerville/Medford (Bridge Street, now Monsignor O'Brien Highway/Massachusetts Route 28). Craigie and associates, who formed the Lechemere Point Corporation, benefited from the building boom that followed, spurred on by their efforts to expand the public street grid.[4] Residential cross streets were constructed and some were named after investors (Otis, Thorndike, and Gore)[5][6] The bridge was sold to the Hancock Free Bridge Corporation in 1846,[7] and became toll-free on January 30, 1858.[8]
The current bridge was constructed in 1910.
Construction of the Museum of Science began on the dam in 1948, and finished in 1951.
