Check out googlemaps. It is a pretty neat site to get directions, set routes, etc.
See this link here for a map I quickly made. If you look close you see white dots along the route. Those force the route to go a certain way. You can drag them around to change route or remove them. Start and finish are marked by A and B. Those can be dragged around also.
