Lancaster Canal: A Heritage Guide
The Lancaster Canal runs for 41 miles through Lancashire and Cumbria, connecting Preston in the south to Kendal in the north. This waterway stands apart from England’s canal network due to its unusual isolation and remarkable engineering.
Key Facts
- Route: Preston to Kendal (with a significant break at the Lune Aqueduct)
- Length: 41 miles (northern section: 14 miles; southern section: 27 miles)
- Number of Locks: 0 in the main northern section; 8 locks in the southern section
- Opened: 1797-1819
- Chief Engineer: John Rennie
Origins and Construction
Local merchants and landowners promoted the Lancaster Canal in the 1790s to transport coal from mines near Wigan to Lancaster and Kendal. The growing textile mills and limestone quarries in north Lancashire needed reliable transport, and roads at the time were inadequate for heavy goods.
John Rennie designed the canal with an ambitious contour route that avoided locks by following the 96-foot contour line across the Lancashire plain. Parliament authorised the canal in 1792, and construction began in 1794. The southern section from Preston to Lancaster opened in 1797, whilst the northern section to Kendal was completed in 1819.
The canal’s most significant structure was Rennie’s Lune Aqueduct, completed in 1797. This five-arched stone structure carries the canal 61 feet above the River Lune and spans 600 feet. The structure cost £48,000 to build—a substantial sum that reflected both the engineering challenge and the quality of construction.
The canal was never fully integrated into the national waterways network. Plans to connect southward to the Leeds and Liverpool Canal at Westhoughton were abandoned in 1799 due to cost. A short tramway was built instead between the two canals, requiring goods to be transferred between boats and wagons.
Working Years and Trade
During the 19th century, the Lancaster Canal carried coal northward and limestone, slate, and agricultural produce southward. Warehouses in Lancaster, Preston, and Kendal handled timber, grain, and general merchandise. The canal served several limestone quarries and powered mills along its route.
The lack of direct connection to other canals limited the Lancaster Canal’s trade. Boats were built specifically for this waterway and could not easily travel elsewhere. By the 1840s, railways were already competing for traffic.
Decline and Present Day
The Lancaster Canal Company sold the waterway to the London and North Western Railway in 1885. Commercial traffic declined steadily, with the last regular cargo boat working in 1947. The construction of the M6 motorway in the 1960s severed the canal at the Lune Aqueduct, permanently dividing it into two separate sections.
The northern section from Tewitfield to Kendal was abandoned and drained in 1955. The southern section from Preston to Tewitfield remains navigable today and is used for leisure boating. British Waterways (now the Canal & River Trust) maintains this section. Various restoration proposals have been made to reconnect the canal across the M6, but none has yet been implemented.
