B81 (Isle of Man)

The B81 is a very short route along Lake Road in the island capital of Douglas. It's sole purpose appears to be as the access road into the islands Tesco store, which hints at a jurisdiction with more road numbers than they know what to do with! The route probably starts at a mini roundabout on the B79, and curves from south to west around the back of the store, coming to an end at the second entrance to the car park. There is some slight uncertainty, however, as the Isle of Man Government GIS doesn't appear to have been updated since the roads were realigned, and still shows the now dead-end eastern end of Lake Road as being the B81, connecting to the A33.
