 MD 117 is a part of the National Highway System as a principal arterial between MD 118 and MD 119 in Germantown.What is today MD 117 was the inspiration for John Denver's hit song "Take Me Home, Country Roads," a song now associated with West Virginia.Songwriters Bill Danoff and Taffy Nivert, who later formed the Starland Vocal Band, wrote much of "Take Me Home, Country Roads" in December 1970 while working in Georgetown.
