the section of Q Street NW in Dupont Circle that is slightly north of the section in Georgetown. In order to accommodate the bridge's approach and to keep the street continuous within Georgetown the Dumbarton House, then known as Bellevue, was moved about northward from its original site in the middle of the current Q Street to its present position on the north side of the Street. The District requested bids to construct the bridge in June 1913, but none of the four bids were within the appropriated budget. The plans were modified so that there would only be five spans rather than seven in order to save costs. The project went out to bid again in November. A.L. Guidone won the construction bid. Its four buffalo sculptures, the largest cast in a single piece of bronze, are by Alexander Phimister Proctor, who also designed the lions on the Sixteenth Street Bridge. The budget to build the bridge was set at $275,000. Construction of the bridge began on March 14, 1914. Construction of the bridge was completed by October 1915, although it took two more months to grade and pave the roads leading up to the bridge. Opening The bridge was officially opened at 4 p.m. on December 24, 1915. It was then known as the Q Street Bridge. The bridge was lit by incandescent lamps. The Commissioners of the District of Columbia officially gave it the name of Dumbarton Bridge on June 5, 1916. According to the Commissioners' written statement, "Dumbarton bridge commemorates the name of the tract of land upon which was laid out the easterly part of Georgetown, and to which Ninian Beall received letters patent from the British crown." The Dumbarton Bridge was added to the National Register of Historic Places on July 16, 1973. See also List of bridges documented by the Historic American Engineering Record in Washington, D.C.
