for the
Charles River in
Boston, Massachusetts as bordered by Nashua Street Park on the south and
Charles Hayden Planetarium to the north and positioned just west of the Charles River Dam Bridge. The first bridge on the site was known as the Canal Bridge, named after the
Middlesex Canal which ran from the Charlestown Mill Pond to Middlesex Village in East Chelmsford Massachusetts; later p/o Lowell. 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. 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. Residential cross streets were constructed and some were named after investors (Otis, Thorndike, and Gore). The bridge was sold to the Hancock Free Bridge Corporation in 1846, and became toll-free on January 30, 1858. The current bridge was constructed in 1910, along with the dam that turned the lower Charles River from a tidal
estuary into a fresh-water basin. This reduced the problematic odor from raw sewage flowing into the river by keeping the formerly tidal lands covered with water. It was completed on June 30, and greeted with a two-hour fireworks display that Fourth of July. Thousands of people watched from the new Boston Embankment (the early
Charles River Esplanade), which took the place of the former tidal flats. Construction of the
Museum of Science began on the dam in 1948, and finished in 1951. The Massachusetts Department of Transportation completed a 2-year project to rehabilitate the Craigie Bridge and to completely replace the drawbridge in 2011. The project required the closure of the Boston-bound lanes from November 6, 2010, through mid December 2010, and again from early February 2011 through mid-April 2011, necessitating traffic detours. This was paid for out of borrowed funds as part of the statewide
Accelerated Bridge Program. In November 2018, a Boston University graduate student was killed by a dump truck while bicycling on the bridge as both turned right onto Museum Way. The next month,
MassDOT announced that dedicated bicycle signals and protected bicycle lanes would be added in summer 2019, dropping automobile traffic to two lanes in each direction. == See also ==
