The Hammersmith flyover is an elevated roadway in West London which carries the A4 arterial road over and to one side of the central Hammersmith gyratory system, and it links together the Cromwell Road extension (Talgarth Road) with the start of the Great West Road. It is one of the first examples of an elevated road using reinforced concrete.[5][7]
