Hello. Thanks for editing. But disconnecting a road to try fooling routers is not the right way. I have reattached the road. There are other ways to let routers (i.e. the software that calculates a route on the map) know that a road is not meant to be used for regular traffic. By disconnecting it, routing would get messed up for people going to the location. I have updated the tags so that routers should not use it unless someone is going to this property. I set this to access="destination".

For odd ones like this, it is best to take a look at how it could be tagged to give people and routers the best idea of what the road is. In this case, the access tag will be helpful. Take a look at the wiki (https://wiki.openstreetmap.org/wiki/Key:access). But sometimes things can be mapped in great detail and a router will still use it even though it should not. In that case it is a router issue and not something to be changed on the map.
