Key Bridge in Washington DC
The bridge was built in between 1917 and 1923 by the U.S. Army Corps of Engineers. The side which enters into Washington DC is right near Francis Scott Key's home (no longer standing). Key is the man who wrote the Star Spangled Banner tune, aka the National Anthem of the United States.

I am a fan of bridges in general, and this one is my favorite in Washington DC.
