 The eastern terminus of present-day Fort Washington Way was originally the site of an army fortress, Fort Washington, from 1789 to 1803.During much of the 19th century, the area south of Third Street was a working-class neighborhood, the Central Bottoms, which had 10,000 residents.From the 1870s to the mid-20th century, the Bottoms gave way to warehouses as residents moved to the West End.
