The Peak Forest Canal
It is a narrow canal constructed between 1794 and 1805 and is fourteen miles long. It connects Buxworth with Dukinfield where it joins the Ashton Canal. The main purpose of the canal was to transport limestone from quarries above Buxworth. There are sixteen locks near the town of Marple that raise the canal a height of 210 feet in a distance of 1 mile.
The advent of the railways and later modern roads led to the decline of the canal and it fell into disuse between 1920 and 1960. An upsurge in leisure boat use led to the canal being restored and reopened in 1974.
The Aqueduct
The River Goyt formed a natural barrier between the lower level of the canal and the nearby flight of 16 locks that raise the canal 210 feet to the upper level of the canal.
The solution was to build this elegant aqueduct to carry boats 100 feet above the level of the river.
The aqueduct became an English Heritage Grade I listed building on 29th March 1966 and the listing tells us that it is a "Canal aqueduct over River Goyt. Between 1794 and 1801. Benjamin Outram and Thomas Brown engineers. Ashlar, dressed and rock-faced stone. 3 wide spans nearly 30m. high. Semi- circular arches rise from large red sandstone semi-circular- ended pylons. They are separated by square battered antae with moulded bases and capitals which form a heavy band below the coped parapet walls which sweep out at each end to be terminated in square piers. Pierced circular opening in each spandrel with ashlar dressings. Tension bars and plates are a later remedial measure. The tow path side (south) has a taller parapet with rounded copings, passing places being formed in the depth of the antae. An outstanding piece of engineering and design on a monumental scale."

Severe damage was caused during the hard winters of 1961/2 and 1962/3 when ice formed in the trough, expanding and causing the parapet wall to collapse. There were proposals to demolish the aqueduct, but there was a major campaign by local canal enthusiasts and itw as eventually, restored and strengthened. It was the success of this renovation that led to the whole of the canal to be renovated and re-opened in 1974.
The towpath is open along the length of the canal giving easy access to the aqueduct. There is a footpath down to the river level, but in Summer months the view of the aqueduct is obscured by dense woodland.
100 years after the canal was constructed The Hope Valley trans-Pennine railway line linking Sheffield with Manchester was built. It also had the challenge of crossing the Goyt Valley and there is a large viaduct very close to this aqueduct.
There is a plaque on the parapet of the aqueduct with the following text.
