In 1957, a study upon extension Route 240/I-70S south of the Capital Beltway and into Washington, D.C., would include two (2) route options roughly paralleling Wisconsin Avenue NW to just south of a tunneled underpass beneath Tenley Circle, and continuing south along through Glover Archbold Park, with one of these route options continuing through the Park before turning east via Whitehaven Park towards Embassy Row, meeting the Inner Loop between 23rd and 24th Streets NW and Massachusetts Avenue, and the other option traveling essentially the entire length of the park to the western Georgetown waterfront to connect with a Three Sisters Bridge to Virginia, a Palisades Parkway, and an expanded Whitehurst Freeway which would connect to the Inner Loop at 27th Street NW and K Street.
