Memorial Drive

Memorial Drive is a 3.9-mile parkway along the north bank of the Charles River in Cambridge, Massachusetts. It runs parallel to two major Boston parkways - Soldiers Field Road and Storrow Drive - which lie on the south bank of the river. The western terminus is in West Cambridge at Greenough Boulevard and Fresh Pond Parkway. The eastern terminus is at Main Street and the Longfellow Bridge near Kendall Square. Memorial Drive is designated as U.S. Route 3 for most of its length, except the easternmost 0.7 miles which are designated as Massachusetts Route 3 . Route 2 is cosigned with US 3 on Memorial Drive between the western terminus and the Boston University Bridge.

Formerly known as Charles River Road, the road was officially renamed "Memorial Drive" in 1923, when Charles River Park was taken over by the Metropolitan District Commission. It is named in honor of those who died in World War I.
