The Iron Trunk aqueduct is part
of the Grand Union Canal built between 1793 and 1805.
A vital link between London and the Midlands. The canal
ran over an aqueduct over the Ouse river in Wolverton.
The aqueduct, built out of bricks in 1805, collapsed
in 1808. After
the collaps William Jessop decided to replace the brick aqueduct with a cast
iron trough. This construction technique was first used only fifteen years
earlier for a single span aqueduct for the Derby Canal and was, therefore, a
relatively new and advanced method (in between the copse of the brick aqueduct
and the construction of the iron one, a temporary wooden aqueduct was used,
built by a local carpenter)! In 1811 the
iron aqueduct was put into use (see little photograph).
Barton swing aqueduct
An ingenious engineering masterpiece enabling one section of
the Bridgewater Canal to be moved into a different position allowing traffic on
the Manchester Ship Canal to continue its journey. When the aqueduct swings open
or closed it is hard to believe that an operation to move 1600 tons (including
800 tons of water) can be conducted so smoothly and quietly.
