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.
Jubilee Parkway The Jubilee Parkway is a pair of parallel concrete viaduct bridges that carry Interstate 10 across Mobile Bay from the George Wallace Tunnel on Blakeley Island in Mobile, Alabama eastbound to Spanish Fort/Daphne, Alabama. The bridges are similar in design to the pre-Hurricane Katrina I-10 Twin Span Bridge near New Orleans, Louisiana. Each of the two bridges is two lanes wide, for a total of four lanes, and 7.5 mi long. The parkway was completed in 1978 and crosses the northern portion of Mobile Bay, running roughly parallel to the nearby Battleship Parkway, with which it has an interchange. It was named for the jubilee phenomena that occurs intermittently in Mobile Bay, but is commonly referred to locally and in the media as the "Bayway".
