Among the exhibits on show is "the innovative double-crane running on rails which enabled both sides of the North Pier, with its diagonal masonry courses, to be constructed at the same time," said Paxton.
In his talk, Paxton described a recently discovered letter, dated 1815, in which Telford explained some of the difficulties he encountered in completing the seaward end of the Aberdeen North Pier, in deep water.
"These had possibly resulted in a shortening of the intended pier in the work as successfully completed in 1816 and which is still in service. This is another example of Telford's bold approach to engineering design generally, which was often at the limits of contemporary practicability," he said.
Paxton had been instrumental in organising events for the 250-year celebrations of Thomas Telford's birth.
Paxton said that the Aberdeen exhibition, curated by museum director John Edwards, with Aberdeen Association secretary Andy Martin and Aberdeenshire Bridge Engineer Donald Macpherson, "includes original Telford drawings of Aberdeen Harbour and an iron turn-bridge, instruments and displays relating to other harbours and bridges."
