South Bridge is a bridge in Edinburgh, Scotland. Largely appearing to be a street, rather than a bridge, at its deck level, it starts at the High Street and finishes at Chambers Street/Infirmary Street. Of its nineteen arches, only the largest, over the Cowgate, is visible. Below deck level are many buildings and vaults, the latter now something of a tourist attraction. Many of the buildings on the deck level have further entrances (and sometimes entirely separate functions) at the level of the streets below the bridge.
