|Route outline (key)|
The A972 came into being in the late 1920s to form Kingsway, the Dundee bypass.
The road then remained the full length of the Kingsway, from the A85 to the A92, for many years and was gradually upgraded to dual carriageway. However, when the A90 was re-routed north to Aberdeen in the 1980s, the majority of the A972 was lost to the new number, with only the easternmost mile or so retaining the A972 number.
The original western end remains as a layby off the westbound A90, with the original A972/A85 roundabout intact but now unclassified and largely used as a lorry park.
