An astute observer will note that the Caldon canal was opened in 1776 and the Leek Branch, carried by the aqueduct in the picture, was opened in 1811 yet the date on the aqueduct is 1841. Unlike the mis-spelling of Hazelhurst, the date is however correct. Originally the main line of the Caldon dropped down from the higher level via a staircase of locks out of sight to the left of the picture. A new more efficient flight of locks SJ9453 : Hazelhurst Locks was subsequently built to replace the staircase and this aqueduct built creating a canal flyover.
