And having it above (= daylight etc) rather than some horrible underpass.
There's a lot of underpass love in some cycling circles, on the grounds that they're easier to build, tend to involve fewer ramps and to be straighter than bridges, but I prefer to be above ground. Underpasses, in addition to being dark, tend to attract litter, graffiti (tagging rather than artistic), junkies, pee and poo (human and animal), and occasional muggers.
