Massachusetts Avenue

Massachusetts Avenue is a major diagonal transverse road in Washington, D.C., and the Massachusetts Avenue Historic District is a historic district that includes part of it.
Appearing in Peter Charles L'Enfant's original plan, Massachusetts Avenue crosses three of Washington's four quadrants.[2] It intersects every major north–south street and passes numerous Washington landmarks. It is a landmark itself, long considered the northern boundary of the downtown as well as home of Washington's Embassy Row.
Massachusetts Avenue is tied with Pennsylvania Avenue as the widest road in the District, at 160 ft (50 m). The two roads run in parallel through much of the city, Massachusetts about seven blocks north of Pennsylvania. Massachusetts Avenue was long Washington's premier residential street, as Pennsylvania was once its most sought-after business address. Both streets were named after states with prominent roles in the American Revolution.
The historic district is an 81-acre (33 ha) area that includes 150 contributing buildings and 3 contributing structures. It was listed on the National Register of Historic Places in 1985. It includes multiple properties that are individually listed on the National Register.[1]
