Foot over bridge fail

When I first viewed this elaborate cross-over-the-traffic-and-get-to-the-metro system, it looked pretty impressive.
Escalators, ramps and stairs all in place to keep us safely above the masses of traffic below.

But it turns out that it was all a waste.
After we'd walked far into the pathways of metal and concrete, there were wires blocking the way.

We thought to just cross over them, but a schoolboy walking behind us said that the path further on was not completed yet and we couldn't get to the metro station that way.

So we had to make our way back down through the maze, once again far away from our destination, blocked by lanes of busy traffic.
Of course, everyone else was also crossing on foot, so we just joined the rest of the chaos and managed not to get run over.
