Summary
[edit]DescriptionLooking W - 21st St SW and Independence Ave SW - Washington DC.jpg |
English: Looking west down Independence Avenue SW at West Basin Drive SW, in Washington, D.C., in the United States.
The land visible here did not exist until 1881, when the Army Corps of Engineers began dredging the Potomac River in an attempt to deepen the channel to prevent flooding. The dredged material was dumped to create the western end of the National Mall (West Potomac Park) and an artificial island and waterway to the Mall's southeast (East Potomac Park and the Washington Channel). This area was complete about 1910. Independence Avenue originally stopped at 15th Street SW, where the shore of the Potomac River used to be. It was not extended westward until 1941 (the idea was that it would link with the western part of the city to help move defense workers about the capital more easily). A 55-foot-wide grassy median exists here to maintain the avenue's park-like appearance. |
