downward-looking view of a long, narrow metal staircase or bridge

downward-looking view of a long, narrow metal staircase or bridge. The structure is surrounded by a wire mesh safety barrier. The steps are made of a grid-like material, allowing one to see through to the ground far below. On either side, there are metal beams and additional grid-like platforms. In the distance, a hazy mountain range can be seen. The weather appears overcast. The structure is nestled within a natural environment of trees and rocks. At the end of the bridge there is another structure that looks like an observation deck.
