the new park facilities in June 2005. In late 2005, the Pennsylvania Department of Conservation and Natural Resources (DCNR) put forward an $8 million proposal for a new observation deck and visitors' center, with plans to allow access to the bridge and a hiking trail giving views of the fallen towers. The Kinzua Sky Walk was opened on September 15, 2011, in a ribbon-cutting ceremony. The Sky Walk consists of a pedestrian walkway to an observation deck with a glass floor at the end of the bridge that allows views of the bridge and the valley directly below. The walkway cost $4.3 million to construct, but is estimated to bring in $11.5 million in tourism revenue for the region.
