Eastern Parkway is a major east–west boulevard in the New York City borough of Brooklyn. Designed by Frederick Law Olmsted and Calvert Vaux, it was built between 1870 and 1874 and has been credited as the world's first parkway. At the time of its construction, Eastern Parkway extended to the eastern edge of the then-independent city of Brooklyn.
The road begins at Grand Army Plaza (the main entrance to Prospect Park) and runs 3.8 miles (6.1 km) east to Bushwick Avenue. The initial portion of Eastern Parkway, west of Ralph Avenue, consists of a main road and two service roads separated by landscaped medians, which include bike paths and walkways. The section west of Ralph Avenue is a New York City scenic landmark and on the National Register of Historic Places. The part east of Ralph Avenue is narrower and is officially known as the Eastern Parkway Extension.
