1) Would it be legal to ride on one of those footpath bridges (not sure if it's footpath only, they're wide) they have to cross those wider ~70kph roads? (first picture of the imageshack link to see what I'm talking about. Grey bits are the footpath and the bridge, white with the yellow arrows are the larger roads, smaller white parts are the smaller streets. The yellow arrows are the direction of traffic and red is my proposed route).
2) On the return trip, would it be alright ride against traffic on the footpath to get back (blue arrows of the same diagram) or at least cross the bridge? (the blue arrow on top is about 100m) Or would I have to find another route (e.g. head in the yellow direction to the next pedestrian crossing, which in my case is not close)
