Because of the mysterious workings of the military mind, cyclists can only travel on one road and in only one direction (downhill towards D.C.) in Arlington National Cemetery. A cemetery superintendent who was forced to retire because of a scandal involving lost graves/gravestones initiated this ridiculous policy. Later superintendents have not changed it.
Nobody can understand or justify this senseless policy. Pedestrians can use the same route and travel both ways. However, cyclists can’t.
If cyclists want to visit Arlington House (a National Park Service property that the Cemetery surrounds), they need to enter through Fort Myer, visit the mansion, and then leave the Cemetery by cycling down to the bottom of the hill. Unlike pedestrians, they can’t return directly to Fort Myer. They need to travel down the hill and then cycle up the hill outside of the Cemetery.
