Paisley's Canal street station, Blackhall viaduct and Thomas Telford connections: 

Thomas Telford and his connection to Paisley:
For over 200 plus years, Telford's monumental and ubiquitous bridges, canals and docks still has such an impact on the transport infrastructure of Great Britain and Europe, that he earned the epithet: The "Colossus of Roads".
In Paisley, his Blackhall aqueduct over the White Cart, was at one time the longest bridge in early canal navigation of the 19th century. It is from the word navigation, that we get the nickname "navvies". Navigators was the word for those that cut canals throughout the length and breadth of Britain.
The Blackhall aqueduct - 240ft in length and 30ft in height with an arch span of 84ft in length, was originally built to carry canal traffic of barges laden with freight of coal, iron, chemicals and other goods.
Opened in 1810 and officially in 1811, the canal was to be converted from a canal, to carry railway carriages over the White Cart river from 1885 onwards and is still in use to this day, with a connection to Glasgow Central and many stops in-between.
