Florida Avenue, Washington, District of Columbia, DC
Significance: Neither L'Enfant nor Ellicott indicated that an avenue was to follow the city boundary. This avenue developed, nevertheless along the outer edge of the planned city squares. Known as Boundary Street until 1893 when it was renamed Florida Avenue, this road follows the path of a natural escarpment. Today it forms the north boundary of the Dupont Circle and Striver's Section National Historic Districts.
Survey number: HABS DC-700
