Brindley Bank Aqueduct
This four-arched structure was built by James Brindley to carry the Trent and Mersey Canal over the river Trent at Brindley Bank, near Rugeley, Staffordshire.
Brindley Bank Aqueduct.
This major feat of civil engineering by Brindley was achieved by first building half the structure on dry land and then excavating a channel used to divert the river under the new structure. This enabled the other half to be built on dry land and when complete the river was let go so that it could flow along both its natural and man-made channels. This technique had the advantage of increasing the size of the channel to provide capacity for floodwater.
Brindley's aqueducts are characterised by being very broad and sturdy structures because they had to withstand the weight of water as well as the mass of clay puddle used to contain it. The canal was designed to follow the natural contours of the land as much as possible and at this point the river Trent should have been crossed on the slant. Instead, the crossing was made at 90º because the technology to build skew arches, that could transmit lateral thrust to the abutments, had not been developed at that time. Consequently, Brindley always made river crossings at 90° and in this instance the canal also has a 90° bend in it at one end.
Dove Aqueduct
Although Brindley Bank Aqueduct is noteworthy, it was not the longest that Brindley built on the Trent and Mersey Canal.
His longest aqueduct is the river Dove Aqueduct off the south side of Deby Rd to the south west of the village of Egginton, Derbyshire. It is understood that this aqueduct has 23 arches but only 12 of them are visible.
It is listed Grade II, List Entry No. 1096525.

Hazelhurst Aqueduct
This aqueduct is situated at Hazelhurst Junction on the Caldon Canal where the canal divides, the main line descending through three locks
in an easterly direction to join the river Churnet, while the Leek Branch continues along the contour to cross the main line on the single-arched Hazelhurst Aqueduct.
This aqueduct was built in 1841 and John Rennie was the engineer for the Leek Branch. It is listed Grade II, List Entry No. 1038095.
