Clara Barton Parkway is an automobile parkway in the U.S. state of Maryland and the District of Columbia. The highway runs 6.8 miles (10.9 km) from MacArthur Boulevard in Carderock, Maryland, east to Canal Road at the Chain Bridge in Washington. Clara Barton Parkway is a two- to four-lane parkway that parallels the Potomac River in southwestern Montgomery County, Maryland, and the far western corner of Washington. The parkway provides access to the communities of Cabin John and Glen Echo and several units of the Chesapeake and Ohio Canal National Historical Park. The Maryland portion of the George Washington Memorial Parkway was constructed from Carderock past Interstate 495 (I-495) to Glen Echo in the early to mid-1960s. The parkway was proposed to continue west to Great Falls and east to Georgetown. However, these proposals never came to fruition and the parkway was extended only to the Chain Bridge in the early 1970s. The Maryland portion of the George Washington Memorial Parkway was renamed for Clara Barton, the founder of the American Red Cross, in 1989.
Clara Barton Parkway begins at an intersection with MacArthur Boulevard in Carderock. MacArthur Boulevard heads west toward Great Falls and the affluent community of Potomac. Clara Barton Parkway heads east as a two-lane highway that expands to a four-lane divided highway ahead of its diamond interchange with an access road to the Carderock Division of the Naval Surface Warfare Center to the north, which features the David Taylor Model Basin, and Carderock Recreation Area of the Chesapeake and Ohio (C&O) Canal to the south. East of the naval lab, the two roadways split for the parkway's six-ramp interchange with I-495 (Capital Beltway). There is no direct access from westbound Clara Barton Parkway to northbound I-495 or from southbound I-495 to the eastbound parkway. The parkway roadways come together in Cabin John just west of parking areas accessible from the eastbound direction to C&O Canal Lock 10 and C&O Canal Lock 8 and River Center. Access to Cabin John is provided by a diamond interchange to a road connecting the parkway with MacArthur Boulevard in that community.
