I still haven’t made up my mind about the Garden Bridge over the Thames, but this interview with the designer, Thomas Heatherwick, has nudged me towards the “yes” camp:

The Garden Bridge is based on the idea that the best cities are ones with maximum ‘walkability’ and are places where city-dwellers (those lonely students with their Kindles and iPads, for instance) can interact with each other. It’s a highly romantic idea — a folly whose purpose, if there is one, is to encourage purposelessness. Heatherwick envisages daydreams, proposals and writing taking shape on his creation, rather than soliciting or mugging.
