Via the Brooklyn Daily Eagle:
On Jan. 28, 1975, Ocean Parkway was designated a scenic landmark. Ocean Parkway runs about six miles north to south from Prospect Park to the southeastern edge of Coney Island. In the 1860s, the parkway was suggested in reports to the park commissioners of Brooklyn by Frederic Law Olmsted and Calvert, designers of Prospect Park, who together had drawn up a plan influenced by boulevards in Paris and Berlin. In 1874, construction was begun and completed by 1880. It resembled Eastern Parkway, which extends eastward from Grand Army Plaza, and had a width of 210 feet, a central roadway, two malls, two side roads and two sidewalks and was lined with trees, benches, playing tables and a bicycle path. The neighborhoods it ran through included Parkville and Windsor Terrace. Such new neighborhoods as Kensington were later built along the parkway.
