[2] The aqueduct was designed by civil engineer John Rennie and constructed by architect Alexander Stevens (died 1796, aged 66).
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).
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.
