What is the bridge near Clark Island made of?
Clark Island (New South Wales) Clark Island is a small island in Sydney Harbour, near the coast of New South Wales, Australia. The island is part of the Sydney Harbour National Park and lies offshore the Sydney suburb of Darling Point, in the eastern part of Sydney Harbour between the Harbour Bridge and the harbour entrance.
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".
