Waterways charity Canal and River Trust has reopened the Lancaster Canal to boaters following a £1.6 million project to repair a breach at Hollowforth Aqueduct.
The canal at the Grade II-Listed aqueduct at Woodplumpton breached in July last year, causing extensive damage where parts of the embankment, towpath and sections of aqueduct wingwall washed away.
The trust’s project team created a plan to rebuild the embankment, reinstate the canal towpath and the footpath underneath the aqueduct, and sensitively repair and restore the aqueduct, using original archive drawings to replace all the masonry in its original position.

The complex repair works, which cost the charity £1.6 million, have included several measures, such as a land drain and bentonite clay liner on the canal bed, to prevent a breach in the future. As Blog Preston reported in February, the repairs were completed after temporary repairs were put in place following the collapse.
The repair has been particularly challenging as the breach was located away from local roads and required a temporary track to be built to the aqueduct, and along the bed of the drained canal, so that materials could be brought to site.
Jon Horsfall, North West director at Canal and River Trust, said: “We’ve been working hard on site since last summer to repair the breach and get the canal back open for boaters and towpath users as quickly as possible. Hollowforth Aqueduct is a piece of living heritage, and we’ve taken care to protect its historical aspects while repairing the damage to make it safe for the future.
“We’ve kept boaters at the forefront of our thinking as we’ve carried out these works, creating an unusual three-sided dam to allow boaters to navigate across the aqueduct before the navigation was closed for the repairs to get underway.
“Thankfully, all that hard work has paid off, the complex repairs have been completed, new measures have been put in place to prevent a breach in the future and navigation has now re-opened for boaters.”
Renowned civil engineer John Rennie designed Hollowforth Aqueduct, using an ingenious engineering solution of three barrel-shaped stone pipes, to carry the Lancaster Canal over New Mill Brook in the 1790s. He later went on to design the iconic Lune Aqueduct, near Lancaster, and also the Caen Hill Lock Flight on the Kennetand Avon Canal in Wiltshire, one of the seven wonders of the waterways.
Jon Horsfall added: “The Lancaster Canal, which is extremely popular with boaters, walkers and cyclists, is over 200 years old but, like so much of our historic canal network, it has endured centuries of use and been battered by the elements, which have taken their toll on one of the country’s few coastal canals. The breach and costly repairs demonstrate the scale of the challenge our charity faces in keeping canals alive.
“We would like to thank everyone, especially boaters and the local community, for their patience and support whilst these complex works have been carried out.”
