The bridge, which has been built by the firm Seiler AG (Steel and metal constructions) in Bönigen, is long, wide and high with a 15% slope. It has four pieces of key supporting steel cables with a 120 tonne loading capacity. Peak Walk is anchored by 20 pieces in the rock. It is expected that the current number of summertime visitors of around 50,000 will double as a result of the new bridge. The designers took the extreme conditions into account, with winds of about . Mountains that can be seen from the bridge include Mont Blanc (the Alps' highest point), the Matterhorn, Mönch, Jungfrau and Eiger, and the bridge has a partial glass floor that afford views down through it. In addition, the bridge became the world's second highest suspension bridge after the Titlis Cliff Walk, which is above sea level. The thin air at high altitudes and poor weather hampered construction work, and summer storms delayed the transportation of construction materials.
