GOOGLE MAPS

[Stichill_imp]

I copied your map to my account so I could edit it. To change the route, first click on the route line. It will change to a lighter shade of blue with a white highlight. Then click on it again and hold the mouse button to drag it to a new road.

Edit: actually, this is very odd. The entire route moved as a unit, keeping the same geometry. On maps I've created, after I've clicked the route to highlight it, I then get a white circle as I hover over the route. I can click and hold to drag this white circle to a new position.
