Mapping a route by mileage

I'm having a challenge trying to map a route using mileage as my "tool". I know there are co-ordinates and I am assuming they can help...somehow?

Sorry, I'm not sure what you mean by "using mileage as my "tool".

Any route will generate a mileage figure.

And if you use the RTA Map Center page, you can obtain estimates of how far a given distance would be along any chosen route.

The way to do this, is to use the Draw Circles tool -- where you can create a radius from any given point from 100 to 500 miles and see where along your route such a distance might put you.

Is any of this related to what you are trying to do?
