Red painted arrows 2

As mentioned some red arrows painted on the roads of Stourport. Although I'm not sure where they start I can now see where they lead and it's a little confusing.

So starting at Areley Common a turn right onto Dunley Road. Approach the bridge and find three straight arrows. Over the bridge into town, up Bridge Street, into High Street and a turn right at the end of High Street with another turn right leading to Lion Hill and another turn right into York Street. Turn left back into Bridge Street, back over the bridge and just past the three arrows a left turn into Harold Davies Drive.

So what the hell is that all about? Why take you over the bridge and back instead of just putting in a right-turn? Who are these meant for?
