Beneath Key Bridge
Traveling on George Washington Parkway along the Potomac River shore requires you to pass under Key Bridge, a regular landmark for commuters, a representation of the best of bridge architecture around the Capitol (where there are a great number of bridges) and on the top of the structure, a car traffic, foot and bike route for thousands of people crossing over from Arlington Virginia into DC/Georgetown, and then back again, everyday.
