Spencer Street Bridge, Steel cantilever bridge across Yarra River in Melbourne, Australia

Spencer Street Bridge is a cantilever girder bridge with a suspended steel span over the Yarra River, linking Spencer Street on the north bank with Clarendon Street on the south. It carries road traffic and trams, and a glass-and-steel covered footbridge built alongside in 1998 connects to the Melbourne Convention & Exhibition Centre.

Construction took place from 1927 to 1930 following a design competition won by engineers Edward Saunders and Alan Wilson. During the building process, workers encountered an ancient tree stump beneath the riverbed that caused a temporary halt to work.

The bridge serves as a meeting point during public events and provides photographers with views of Melbourne's central business district and river landscape.

The bridge carries road traffic and trams between Spencer Street on the north bank and Clarendon Street on the south. A separate glass-and-steel covered footbridge, built alongside in 1998, gives pedestrians their own crossing of the Yarra.

During construction, workers discovered an 8,000-year-old red gum tree stump 20 meters below sea level, causing a three-week delay in the project.
