Took some pictures here (https://queerthoughts.org/media/osm-notes/3743640_1.jpg; https://queerthoughts.org/media/osm-notes/3743640_2.jpg; https://queerthoughts.org/media/osm-notes/3743640_3.jpg). The footway has two sets of stairs, each with two steps. Hope this helps. (Please excuse the awful picture quality, I did not have my camera with me.)
