Houghton Park Pedestrian Skyway: Corning, New York.

One doesn't usually expect a covered bridge to be made of glass. Unless it belongs to Corning Inc. Glass has been integral to the architectural identity of this company, located in upstate New York, since Harrison & Abramovitz designed the Corning Glass Center and Administrative Building in 1950-53. Ironically, however, the glass used in the bridge is not made by Corning. The company once known as Corning Glass Works no longer produces architectural glass. Only Steuben, renowned for its handblown-glass luxury objects, still has a factory at this location. Because of the influx of museum visitors in addition to Corning personnel, the company needed a 200-foot-long bridge to take pedestrians from a 700-car garage and a parking lot for a 1,000 cars across the main boulevard. Hascup/Lorenzini Associates designed the bridge.
