The Horseshoe Bridge in Perth, Western Australia, connects the Perth CBD to Northbridge, carrying William Street over the Fremantle railway line. It was constructed in 1904, with the horseshoe shape designed to fit the approach ramps into a constricted site. The bridge was closed from the end of 2009 to early 2010 to enable conversion to two-way traffic flow.
The Horseshoe Bridge is a classically inspired brick and stucco traffic bridge located in the central business district of Perth, Western Australia. The bridge connects the Perth CBD to Northbridge by allowing traffic to continue along William Street and pass over the railway lines, to the west of Perth railway station. The bridge's name is derived from its shape: a horseshoe. This design was an innovative solution to the problem of bridging a railway within tight urban constraints.
The bridge is a handsome structure of its period and a very sophisticated piece of urban design. The main structural elements of the bridge are of steel, and it is supported by a series of semi-circular arches with rendered decorative treatment. Many of the arches on the Wellington Street elevation have been enclosed with glass, which in the past created shop fronts to retail spaces behind. The balustrades are rendered concrete and sculptures of swans decorate the end piers. These were specifically designed for the bridge project.
It is well integrated within its context and its value goes beyond mere transport. The winding form adds vitality to the Perth railway station precinct and the architecture contributes to the streetscape of Wellington Street. The bridge has four traffic lanes, which, in 1986, carried approximately 18,000 vehicles per day into the city. The eastern footpath gives direct access to both city rail station platforms.
The bridge was constructed in 1904 to reduce train-induced traffic congestion in William Street. During the last decade of the 19th century, WA's Engineer-in-Chief, C.Y. O'Connor, had overseen the construction of Perth's suburban railway system, which radiated out from a central railway station in Wellington Street in the city. As the line effectively cut the city off from its northern suburbs, a number of bridges and level crossings had to be built to connect the two areas. A bridge over the railway was constructed between Barrack and Beaufort Streets in 1894, as well as two pedestrian crossings, however by the mid 1890s there were seven lines and the William Street crossing was closed for most of the day as railway traffic continued to increase.
