Road Ahead Closed

Its a twisty turny single track road over the back of beyond and is about one and a half miles long. It cuts out a route of around 4 miles on the crowded evening main traffic routes.

It looked to me like the sign was off to one side so the route was probably clear so I just went right ahead and ignored it. After a mile and a quarter, I discovered that it was closed at the very end where it would have joined the main road again. I had to go all the way back.

One day to the weekend.
