Sydney Harbour Bridge

Sydney Harbour Bridge

Climb to the top of the Sydney Harbour Bridge

PROJECT OVERVIEW

The Sydney Harbour Bridge,  has spanned the harbor since 1932 after nine years of construction.  It is one of the longest one-bow bridges in the world with a length of 1,150 m; the bow itself being 504 m long. Thus the bridge is just 66 cm shorter than the Bayonne Bridge in New York, but much heavier; 50,300 tons of steel were used in the building process. The Bayonne Bridge was completed just four months earlier thus not allowing the Sydney Harbour Bridge to claim the longest arch bridge in the world.  Each day over 200,000 cars cross the bridge paying a toll of $2 each when entering the city.  The Bridge was designed after the Hell Gate Arch Bridge in New York, but it was much longer and much heavier per linear foot.
