Volunteers have been giving up their spare time to help progress on the latest phase of restoration of the Chesterfield Canal.
The waterway, which runs from Chesterfield, along the southern edge of Sheffield towards the River Trent, is being spearheaded by the Chesterfield Canal Trust.
The organisation recruited volunteers to help its working party on the construction of the Staveley Town Lock – the next phase of rebuilding the canal after a new Staveley Town Basin was completed.
The lock will take the canal beneath a new road and railway.
Rod Auton, spokesman for the trust, said: “Following the opening of Staveley Town Basin in January 2012, there has been only sporadic work on the lock.
“However, things started in earnest at our Canal Festival at the end of June. Since then hundreds of blocks and bricks have been laid, a secure compound has been built for construction facilities, footings for a new washwall have been excavated and concrete poured for foundations.
“In addition several trust members have learnt how to drive excavators and dumper trucks. Everyone working on the project is a volunteer, many giving up their holidays.”
Mr Auton said the trust has raised over £30,000 so far towards the lock project with its Donate a Brick appeal, which will continue, accepting amounts from £5 upwards.
But a new funding drive is set to be launched.
Mr Auton said: “The money is now being spent at an alarming rate, so the trust is making a fresh appeal.
“In the next few weeks, we will be pouring hundreds of cubic metres of concrete. This is delivered by lorry and is hugely expensive.
“People can donate a cubic metre of concrete for £80.”
