CONSOL Energy Wing Tip Bridge - Mott MacDonald. "Each end of the bridge passes through a V-shaped structure made of six steel masts, raked outward at the top. Between the masts and abutments, the cables are splayed to provide extra stability against lateral motion. The resemblance of the slanting masts to the wing tip feathers of a flying eagle inspired the name Wing Tip Bridge… A unique feature of the bridge is that pedestrians can cross in one of two ways: on a traditional level deck or on secondary walkways that follow the cables and pass above and then below the deck, sometimes at an angle of up to 10 degrees."
Consol Energy Wingtip Bridge (Boy Scouts Bridge) - schlaich bergermann partner. "The design of the bridge was to be adventurous and the crossing of the bridge was to be an experience in itself. To that end, the scouts are able to walk not only on the bridge deck but also along the cables of the bridge on a steel walkway. The cables pass over the tops of the masts and below the main deck of the bridge allowing the scouts to see the bridge from multiple perspectives. The masts are spread to form a V in section which evokes the tips of eagle’s wings, the symbol of the Boy Scouts."
