It's in the top right of this map on the main car park

Seems logical to me as it gives cyclists and peds a route through the car parks in which cars won't be reversing
Pretty sure that I've parked in that car park but I don't think the cycle path was there then - about 10 years ago.
How can it do that? It's only 30m or so. The car park is a couple of hundred each way.
