A through arch bridge, also known as a half-through arch bridge and through-type arch bridge, is a bridge made from materials such as steel or reinforced concrete in which an arch rises above the deck so it passes through the arch. Cables in tension suspend the deck from the arch. One of the most famous bridges of this type is the Sydney Harbour Bridge in Australia. The Hell Gate Bridge in New York City, the Bayonne Bridge in New Jersey, which is longer than the Sydney Harbour Bridge, as well as the smaller, near-twin Bourne Bridge and Sagamore Bridge over the Cape Cod Canal, are very similar. |
