Allington Bridge is an accommodation bridge, 48 miles 73 chains from
Reading, carrying a farm track from Allington over the canal to
nowhere very much.

Allington Bridge from the westward side. These bridges are all the
same; all individual.
|
|
|
|
Brickwork in Allington Bridge; courses of english bond, and some
english cross bond though that may be by chance, and skewed brickwork
to throw stress into the batter of the arch. I don't quite understand
why this is done on some not other bridges; this bridge is hardly
oblique to the canal.
|
|
|
While building the canal, John Rennie, the engineer, was experimenting
with ways to build a bridge at an angle yet keeping the sides of the
arch parallel to the canal. This and other skew bridges show some of
his tentative designs.

Brick arch, batter, shadow, footings, etc

There is a stop groove, a slot into which stop planks to dam the canal
with a stank can be fitted, in the bridge.

The stop groove on the opposite side; well maintained with an iron
lining.
