I do not use mapquest so much, maybe it is the same as googlemaps. Googlemaps lets me drag the starting point and destination around map.
Here is a link that should have "somewhere in calument" to spanish springs.

One neat feature is the ability to drag the route around. See the white dot on el camino real? That is there because the original route was out on 441/27 and I dragged it to use elcamino real.

hope that helps, play around with it. IMO a pretty powerful map for free.
