Horseshoe Bridge, Road bridge in Perth, Australia

Horseshoe Bridge is a curved road bridge in central Perth, Australia, carrying William Street traffic over multiple railway lines. It has four lanes and pedestrian walkways on both sides, linking the central business district to areas further north.

The bridge was built in 1904 to carry William Street over the Fremantle railway line, replacing a level crossing that was closed for most of the day once seven lines ran through it. With no land available for approach ramps, the horseshoe curve was the only way to achieve gradients for horse-drawn vehicles. It replaced two pedestrian overpasses, which made foot crossings longer, but traffic between the city's north and south grew strongly.

Cast iron swan sculptures sit on the end piers of the bridge, referencing the Swan River that runs through Perth and gives Western Australia its bird emblem. These decorative details are among the most noticeable features for people crossing on foot.

The bridge is open to both pedestrians and vehicles, and it sits close to Yagan Square and the central business district. Those on foot will find the most direct access from William Street.

The arches along Wellington Street were once enclosed in glass and used as small retail shops, so the bridge functioned as both a crossing and a shopping corridor at the same time. This arrangement is no longer visible today, but it shaped how the structure was used for decades.
