How this seemingly simple bridge became a great piece of architecture has puzzled some. In most other cities it would be just another collection of girders spanning the water. But for Sydney, the bridge is symbolic of their city and a source of pride. So much so that there is a Harbour Bridge Museum at the base that details the bridge's construction. At 1,650 feet, the Harbour Bridge is one of the longest arch bridges in the world. It is 439 feet above the water and weighs 52,000 tons. More importantly, the bridge is one of the best vantage points for photographing the city. If you visit, most people will notice the eight lanes of traffic, the two pedestrian walkways, and the twin rail lines. But not everyone is aware that there is a better way to experience the bridge. You can actually climb to the top of the bridge arch legally. These tours were suspended decades ago, but were resumed in early 2001. Visitors wear special jumpsuits that are clipped to the bridge so you don't slip and plummet to the freeway or the water below. For the truly adventurous, these tours are also available at night.
