Today’s Street Level takes us to Columbia Road in Northwest D.C. Columbia Road starts as a residential street, lined with working class homes, not far from the Washington Hospital Center. It runs through a number of different neighborhoods, including recently revitalized Columbia Heights and bustling Adams Morgan, and ends just above Dupont Circle.
At one time, Columbia Road formed the northern border of Columbian College (which we know today as The George Washington University and which has since relocated).
Edited (February 2015): I've just learned courtesy of the Washington Post that Dwight Eisenhower and his wife, Mamie, lived at the Wyoming (in the last picture) from 1927 to 1928 and again from 1929 to 1936 while he was stationed in Washington as an Army major. The Post's slideshow on the homes of the Presidents is fascinating.
