What is the bridge near Clark Island made of?
Sydney Harbour Bridge The Sydney Harbour Bridge is a steel through arch bridge across Sydney Harbour that carries rail, vehicular, bicycle, and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of Sydney, and Australia. The bridge is nicknamed "The Coathanger" because of its arch-based design.
Gravina Island Bridge The Gravina Island Bridge, commonly referred to as the "Bridge to Nowhere", was a proposed bridge to replace the ferry that currently connects the town of Ketchikan, Alaska, United States, with Gravina Island, an island that contains the Ketchikan International Airport as well as 50 residents. The bridge was projected to cost $398 million. Members of the Alaskan congressional delegation, particularly Representative Don Young and Senator Ted Stevens, were the bridge's biggest advocates in Congress, and helped push for federal funding. The project encountered fierce opposition outside Alaska as a symbol of pork barrel spending and is labeled as one of the more prominent "bridges to nowhere". As a result, Congress removed the federal earmark for the bridge in 2005.
