Braddock Rd is so named as it was believed to be the route of the English General Edward Braddock's force during the French and Indian War. At the outset of the Braddock Expedition, the force was split into two groups. Braddock led the first group across the Potomac near Rock Creek and up to Frederick and Sir Peter Halkett led a second group through Northern Virginia. Halkett's group marched past the Old Fairfax County courthouse (today Tysons Corner) and up to Coleman's Ordinary (today Northern Herndon, Virginia). It is unlikely that today's Braddock Road was the actual route taken by Halkett's group. Rather, they roughly followed the route of present-day Leesburg Pike (Route 7).
