Washington D.C. to Pittsburgh
OK, anyone know of a site where I can lay out my route and get the mileage? To get to Pittsburgh I usually take the Capital Beltway (495) to 270, to 70, then to 76W (The PA turnpike). I know there's another way (pick up the nat'l freeway (Rt. 68) in Maryland and take it to 79N in West Virginia, then up to Pennsylvania. Anyone know how comparable the mileages are? If so, please let me know!

What you'll need to do is see how the site plots the route for you. Then you can go through it again with your own waypoints and add them up.
Hope this helps.
