Lune Aqueduct Access Steps - Lancaster, UK - Outdoor Stairways on Waymarking.com

The Lancaster Canal is a canal in the north of England, originally planned to run from Westhoughton in Lancashire to Kendal in south Cumbria (then in Westmorland). The section around the crossing of the River Ribble was never completed, and much of the southern end leased to the Leeds and Liverpool Canal, of which it is now generally considered part.

Of the canal north of Preston, only the section from Preston to Tewitfield near Carnforth in Lancashire is currently open to navigation for 42 miles (67.6 km). The canal is a mainly rural route and the towpath is open along the whole route including the aqueduct. It provides a flat route for both walkers and cyclists.

The aqueduct is 664 ft (202.4 m) long, 61 ft (18.6m) high and 20 ft (6.0 m) high and has 5 arches which cross both the river and an access road alongside the river.

The access road provides good views of the aqueduct from ground level and also carries SUSTRANS national cycle route 69.

The aqueduct is a Historic England Grade I listed building with the following text. link

Lancashire Canal Lune Aqueduct is listed at Grade I for the following principal reasons:

Historic interest: the Lancashire Canal system, and associated buildings, designed by celebrated engineer John Rennie, who also laid out Rochdale Canal, Aberdeen Canal, the Crinal Canal, the Royal Canal of Ireland, and the Royal Military Canal; and was a key figure in the expansion and improvement of a number of London docks during the Napoleonic wars of the early 1800s; Degree of survival: largely in it's original form, with only minor alterations such as the lining of the channel with concrete; Date: very early canal structure, having been completed in 1797.

HISTORY

The Lune aqueduct was designed by Lancashire Canal engineer John Rennie, and it is often claimed to be his best work. It took three years to build and was completed in 1797 at a cost of £48,321. The building itself was constructed by Scottish architect Alexander Stevens, who died before it reached completion, with his work on the aqueduct being completed by his son.

Work began to restore the aqueduct in January 2011, and was completed in March 2012. The work involved restoring the canal channel, masonry repairs, removing graffiti, and improving public access. The project cost £2.4m, and was funded by British Waterways, Lancaster Canal Trust, English Heritage and the Heritage Lottery Fund.

DETAILS

The Lune Aqueduct is one of the most out-standing features of the Lancaster Canal, often being referred to as a masterpiece of civil engineering. It carries the canal 664 ft (202.4m) across the River Lune at a height of 61 ft (18.6m).

MATERIALS: Constructed of squared rock-faced sandstone blocks and sandstone ashlar.

PLAN: The aqueduct consists of five semi-circular stone arches supporting a stone trough, separated by panelled buttresses above triangular cutwaters. The supporting piers rest on piles of specially imported Russian timbers driven deep into the bed of the river. The parapet has 3 balustraded openings over each arch.

The piers themselves were of hollow construction, built in stone and strengthened by iron bars. When completed, the hollow centres were filled in with rubble. Huge coffer dams held back the river and the water was pumped out using primitive steam engines. Wooden scaffolding was used to support the structure of wedge shaped stones. These formed the masonry arches until each of the final keystones was in place.

The trough carrying the 20 ft (6.0m) wide canal over the aqueduct is semi-circular, and is now concrete, but was originally lined with stone. Its curving side walls were 18 ins (46cm) thick and the bottom was 1 ft (30cm) deep with 3 ft (90cm) of puddled clay to make it watertight. The bottom of the channel contains a plug which could apparently be pulled to allow the aqueduct to be drained into the river to allow repairs to be undertaken.

SUBSIDIARY FEATURES: The west side the central arch has a keystone carved to represent Lancaster Castle Gateway, and includes a latin inscription which translates as "Old needs are served, far distant sites combined. Rivers by art to bring new wealth are joined”. This is followed the names and dates of the designer and architect: 'QUAE DEERANT ADEUNT: SOCIANTUR DISSITA: MERCES FLUMINA CONVENIUNT ARTE DATURA NOVAS. A.D. MDCCXCVII. ING. I. RENNIE EXTRUX. A. STEVENS. P. ET F.'

On the east side in the same place is the inscription 'TO PUBLIC PROSPERITY.' Below the parapet is a Doric entablature having a strongly projecting cornice.
