Can someone give me the directions to use VA-24 through Roanoke to get to Smith Mountain Lake? I have tried MapQuest, etc., and each time the directions are to turn left off VA-24 Elm Avenue to get on VA-116. We want to follow Rt. 24 to get to VA-122 (Booker T. Washington Hwy.), but we cannot remember exactly how that Route 24 goes through Roanoke. Thanks for any help you can give.
