Navigable aqueducts
played an important role in getting Great Britain’s industrial
revolution off the ground. In an age when railroads and commercial
highways had yet to be invented, these elevated artificial water bridges proved their worth at the time and have continued to do so for over two hundred years.
The Lune Aqueduct (above) supports the Lancaster Canal and towpath over the River Lune in
Lancaster, England. Designed by John Rennie following classical
architectural techniques, the 19 meters (62 ft) aqueduct over the River Lune is supported by 5 arched brick piers. It was built between 1794 and 1796, and its cost ran way over
budget preventing the Lancaster Canal from connecting to the main canal
network via the never-built aqueduct over the Ribble river. The Lune Aqueduct not only looks Roman, it was built using Roman
technology adapted by Rennie, to ensure the
stone bed of the aqueduct would not leak, Rennie specified the use of
Pozzolana powder, a Roman invention that allows concrete to set
underwater. The Lune Aqueduct is
still in use today.

Avon Aqueduct |
At 250 meters (810 ft) long and 26 meters (86 ft) high, the Avon
Aqueduct is Scotland’s longest and tallest aqueduct. Built after a
design by navigable aqueduct pioneer Thomas Telford, the Avon Aqueduct
features a cast iron trough supported by 12 brick and masonry arches.
The aqueduct runs through Muiravonside Country Park,
providing a spectacular scenic view from the park’s lush landscape or
from the top of the aqueduct itself.
The Avon Aqueduct carried the Union Canal and is located near Linlithgow
in West Lothian, Scotland. Three great navigable aqueducts facilitated
water traffic on the Union Canal, which opened in 1822 and was closed in 1965, with the Avon Aqueduct being the largest and longest of the three.

Pontcysyllte Aqueduct |
Engineer Thomas Telford designed the Pontcysyllte Aqueduct in Wales.It is the longest and highest
aqueduct in Britan at 1,007 ft (307 m) long, 11 ft (3.4 m) wide
and 5.25 ft (1.60 m) deep, it carries the Llangollen Canal over the River Dee in Wrexham, northeast Wales.
The Pontcysyllte (pronounced
“pont-ker-suth-tee”) Aqueduct may
have been the height -literally – of technology at the time, but its
construction involved some surprisingly unusual and ancient techniques.
One example is the mortar used to cement the masonry piers: it was made
from water, lime, and ox blood!
It is often the Pontcysyllte Aqueduct in TV programs and tourist publicity shots. It was added to theUNESCO World Heritage List
in 2009. The aqueduct is used regularly by pleasure boats and
commercial “narrowboats”, and once every 5 years it’s drained (by
removing a plug) for cleaning and routine maintenance.
