commuting around Boston University's main campus, also known as the Charles River Campus, and is frequented by pedestrians, cars, motorcycles, vespas, bikes, skateboards, scooters, both the inbound and outbound MBTA Green Line B branch trains (running above ground), both the inbound and outbound MBTA #57 & #57A buses, the Boston University Shuttle, charter buses, and trucks alike. Walking from one end (Kenmore Square) to the other end (Packard's Corner) or vice versa takes about 25–35 minutes. There are nine MBTA Green Line B branch stops between Kenmore Square and Packard's Corner (inclusive) within these 1.5 miles and they are very commonly used for transportation from one end of campus to the other, and beyond. Moving farther from the city and closer to the outskirts and the suburbs, the Kenmore Square stop is followed by Blandford Street, Boston University East, Boston University Central, Boston University West, St. Paul Street, Pleasant Street, Babcock Street, and Packard's Corner. Together, these nine stops are renowned for representing Boston University's presence in and around this 1.5-mile stretch of Commonwealth Avenue. In addition, a majority of the BU student body, which consists of approximately 33,000 enrolled undergraduate and graduate students, resides alongside these stops, creating a particular neighborhood that identifies this area. History The Commonwealth Avenue Mall was designed by Arthur Delevan Gilman. Frederick Law Olmsted designed the Newton portion of Commonwealth Avenue and included the parkway as part of the Emerald Necklace park system. The first statue on the Commonwealth Avenue Mall was erected in 1865 at Arlington Street. The Newton end of the roadway was constructed in 1895 with a line of the Middlesex and Boston Street Railway in the median. In 1923, the stretch of Commonwealth Avenue between Warren Street and Sutherland Road became the first street paved with concrete in Boston. Streetcar service was cut back to its present terminus at the Boston border in 1930 and buses last ran on Commonwealth Avenue in 1976. An amusement park and ballroom known as Norumbega Park was built at the end of the line on the Charles River in 1897 to increase streetcar patronage. The eastern half of the Newton section of the road is listed on the National Register of Historic Places as the Commonwealth Avenue Historic District. The mall that includes the landscape features, monuments, street furniture and fences that are bounded by Kenmore Street, Arlington Street and Commonwealth Avenue was designated
