Always a difficult one, at times you just have to admit that the area is too complex to be mapped on a single sheet (but can choose to use different maps for different levels). Alternatively a bit of creativity with colours is good - in the Barbican we have been allowed to run along the top of a canopy (but also pass underneath it). At Oxford this year a raised walkway was mapped as a darker Brown which again you could run along or under. For Brighton (http://www.brightoncityrace.org.uk/) we have a three level promenade and I've chosen the Oxford approach to map the middle layer. Personally I'd like to see this become the norm rather than use different shades of brown to depict different potential levels of traffic, something which is common on many sprint/urban maps.
