This is a road - of which we do have a few. Even double ones like this main road. Luckily they are without too much traffic. Unless you are on the road when the ferry comes in at Tarbert. This was not one of these moments.
There is another big road down Uig way. You go down loads of single track then all of a sudden there's a road like a motorway for a few miles before that too suddenly goes back into single track. Well, I suppose they have to waste EU money somehow!
