I've often wondered about this and can't figure it out. Why don't Google Maps and the likes have a way to say: that road is closed! Often it'll keep sending you back to the same road no matter how far away you drive (even in the opposite direction) , because it's much closer than any other way.
But I want to tell it that the bridge is jammed and driving 25 minutes off my path, is better than waiting 2 hours for the bridge to work again. In this example I know that there's another bridge about 7 miles away "in the wrong direction". But I need to cross and this current bridge is not an option.
Why don't they have a button to click, "this road is closed"
