Tietgensgade is a street in central Copenhagen, Denmark. It runs from H. C. Andersens Boulevard in the northeast to Kvægtorvgade at the Meat-Packing District in the southwest, linking Stormgade in the city centre with Ingerslevsgade and Halmtorvet/Sønder Boulevard in Vesterbro. The street follows the rear side of Tivoli Gardens and Copenhagen Central Station. The viaduct that carries it across the railway tracks at the central station is known as Tietgensbro (Tietgen's Bridge). A series of staircases and lifts provides direct access from the viaduct to the station platforms.
