@Ronald-Weaver That is a bad experience. I have created an account at https://mydrive.tomtom.com. This ist free and you can forehand upload your route. There is a functionality in Myroute-App save as to Mydrive. Then you can check the route there for road work. That is what I do with my routes.
If you are on the road and you come to a closed road you can use the skip function at your device.
