This bridge was constructed so that workers in the industrial area could have access to the local railway station, so GZ can be easily accessed from either direction.
Unfortunately, it is not a cache friendly bridge, so an old hag had to do what an old hag does.
Please be careful that you don't break the cache, and replace it exactly as you found it.
You will have to bring your own writing stick.
Please note that the power lines have been known to play havoc with GPS signals
