Stairway To Where?

What is going on here? If you look at these stairs there doesn’t seem to a whole lot going on. They are down the side of a bridge over the river Medway. You can’t see that to actually get to this point you have to climb over some armco from the path but that’s not my biggest issue with them.

If you look more closely you will see that there isn’t a route to the left at the bottom of the stairs. There is just a slope. No flat path for walking on. Just slope. I don’t understand what the intentions of the designer were. The fence implies there should be a wlakway. The reality is there isn’t one. Maybe I’m just not meant to be there.
