Spiral

I was in East Kilbride today and I believe at one time it was referred to as polo mint city by lorry drivers, this was due to the number of roundabouts in the town.  The most famous of these roundabouts is The Whirlies which nowadays has traffic lights but was more infamous when it didn't have them as nerves of steel were required to use it.  This is a spiral pedestrian bridge and it looks better because the sun is shining.
