This Grade II listed structure which takes the canal over the river Colne west of Milnsbridge, is being repaired to make it waterproof and structurally sound. The work involves strengthening of the arch with concrete infill, construction of a reinforced concrete channel and work to sections of masonry including removal of vegetation, replacement of weathered stone and repointing.

Initial work involved making an access across the canal and diverting of the gas main to a temporary route. This photograph shows staging being erected to gain access to inspect the spandrel walls.

The complete channel within the aqueduct has been dug out.

With the top of the masonry arch visible, concrete has been placed to provide a supporting saddle.

The concrete saddle bearing on the abutment is visible in this picture. The towpath has also been entirely excavated.

The new concrete channel has been fully formed.

The completed aqueduct in July 2000.
