Thanks for the links. I had a feeling that it was most likely forbidden, but was not sure. As far as nuisance goes I think that cyclists are actually more of a problem if they do use the bike path that is on that bridge, because it is shared with pedestrians who are rushing to catch their bus/train. From my experience, If I enter the bridge before the bus does, there is no way it is catching me. Yes I don't go 50km/hr, but I also don't stop at every buss stop and if I do see a bus behind me I always let it through, so there has never been an issue. Nevertheless law is law and I suppose I will look for another way.
