The cycle "ramp" on the bridge is worse than useless. On the rare occasions that I do cycle that way I just carry my bike up and over but that's when I have my light road bike - there is no way inthe world I would use the ramp if I was, for example, wheeling it over with my daughter in her child seat - it's a narrow gully that is positioned too close to the stair rail (meaning the bike has to be wheeled at an angle) and form memory, on the German Bridge side, only starts a couple of stepps down from the top.
I agree that making the bridge safe is the initial concern but it really does need a complete rethink.
