 US 29 roughly bisects Virginia into eastern and western halves, and along with Interstate 81 in western Virginia, and 85/95 farther east, provides one of the major north–south routes through the Commonwealth.Since 1928, when Virginia General Assembly passed Senate Bill 64, much of US 29 in Virginia is known as the Seminole Trail.Through Northern Virginia, it is known as Lee Highway, except in Falls Church, where it acts as the east/west divider for city streets and is called North or South Washington Street.
