A recent edition in the Alexandria area is the creation of Jones Point Park, which happens to be partially under the Woodrow Wilson Bridge. Much of the area was closed off with uncertain ideas of what it's use would be, but the National Park Service has made it into an interesting addition to the trail and park system in the area. The park connects the Mount Vernon trail that goes through Old Town Alexandria (from higher north along Reagan National Airport and into D.C.) and the section after the bridge which leads south to historic Mount Vernon. They have created basketball courts, playgrounds for children, BBQ areas, boat launch areas, fishing spots, and walking paths that wander through marsh and park lands originally surveyed as part of Washington D.C. back in the late 1700s. Local runners, bikers, and walkers use the paths as a scenic link under the bridge—it can provide a bit of respite from central Old Town but not too far away. Make sure to see the rudder from a WWI-era merchant ship salvaged in the Potomac near the bathrooms and basketball courts directly under the bridge.
