Looking across the aqueduct from the eastward end.
Avoncliff Aqueduct carries the canal across the River Avon and the railway, and crosses the canal to the other side of the valley. The towpath roves from north to south side of the canal using the southern arch of the aqueduct.
the aqueduct is built of ashlar stonework and rusticated stonework, etc, in Bath Stone, 330ft long. The aqueduct is 67 miles 19 chains from Reading.

The aqueduct has three arches with a wide cornice. The central arch is elliptical, spanning 60ft; the side arches are semicircular, spans 34ft. The south arch has sagged, this occurred soon after building as the structure settled. It was designed by John Rennie, completed 1797-98. It is repaired with brickwork, mostly unsympathetically, and now has a concrete lining.
The aqueduct has a number of mason's marks on its stones.

date marks found on the aqueduct suggest a completion date 1797. But, a company report to subscribers, 26 June 1798, states:-
... The Avon Cliff Aqueduct is finished, except the inverted arch. ...
Rope marks on the parapet; when you consider the angles it is hard to see how these got here.

The aqueduct bed is now concrete, hopefully sealing leaks properly. Part of the new work was to place steps and hand holds to help boat crews off, this safety provision now blocked by the ?safety provision of the fencing.
To eastward of the north side is Avoncliff Halt, just an unstaffed station where you must hold your hand out to stop the train.
