Peace, I needed to travel only the interstate. Though it provided 3 routes. The quickest was partially non interstate and it would not allow me to go via only the interstate, and it would not allow me to delete not the non interstate way. Maybe my 1st time I fail to know how to navigate the app. Some other time, will give it a go again, when there is more time to see if what I need can happen. Thank you though for trying to help
