South Bridge, Edinburgh

South Bridge is a bridge in Edinburgh, Scotland, starting at the High Street and finishing at Chambers Street/Infirmary Street. The bridge is constructed of nineteen arches, but is now almost entirely enclosed by buildings on both sides, exposing only the largest arch, where the street crosses the Cowgate. Below deck level are many buildings and vaults, the latter now something of a tourist attraction. Most of the buildings on the deck level have separate entrances (and sometimes entirely separate functions) at the level of the streets passing below or parallel to the bridge.
