Construction

The aqueduct was designed by civil engineer John Rennie and constructed by architect Alexander Stevens (died 1796, aged 66).[3][4] The cost of the construction was close to £50,000.[5]

The aqueduct is a traditional structure of that time, consisting of five stone arches supporting the stone trough. Within the piers, special volcanic pozzolana powder was imported to be mixed with cement, which allowed the concrete to set under water.[3] Because of the rush to finish the initial stages, before the winter floods, the construction was carried out around the clock and the final bill for the project was over £30,000 over budget (2.6 times the original estimate). This vast overspend was the reason that the Lancaster canal was never joined to the main canal network – there wasn't enough money for the planned aqueduct over the River Ribble at the southern end of the canal.

Recent restoration

Work began to restore the aqueduct in January 2011, and was completed in March 2012.[6] The work involved restoring the canal channel, masonry repairs, removing graffiti, and improving public access. The project cost £2.4m, and was funded by British Waterways, Lancaster Canal Trust, English Heritage and the Heritage Lottery Fund.[6]

Inscriptions

The structure bears two inscriptions:[7]

  • North side: "To Public Prosperity"
  • South side: "QUAE DEERANT ADEUNT: SOCIANTUR DISSITA: MERCES FLUMINA CONVENIUNT ARTE DATURA NOVAS. A.D. MDCCXCVII. ING. I. RENNIE EXTRUX. A. STEVENS. P. ET F." which can be translated as: "Things that are wanting are brought together / Things remote are connected / Rivers themselves meet by the assistance of art / To afford new objects of commerce. AD 1797. Engineer J Rennie. Built A Stevens father and son" (translated from the Latin)
