No worries. At long as u are careful about where u are stepping, the risk of falling through can be mitigated somewhat. Metal fatigue is a far worse danger. You cant see it, so if u are planning to cross the bridge, my best advise is to try and step on different section of metal. I have done the crossing once some time back - it was an experience. You can still take pictures of both sides if u dont cross the bridge. Just involves walking across using the sturdy pedestrian bridge 50 meters away. Alternatively, you can drive and park @ 2 different locations. Hope the attached map helps.
