Swansea Canal restoration work starts after 40 years

Volunteers working to restore the historical Swansea canal have enlisted an unusual ally - the engineer tasked with filling it in back in the 1970s.

Swansea Canal Society and Glandwr Cymru - the Canal & River Trust in Wales - are working to reopen parts of the 16 mile (26km)-long canal.

They have made contact with John Evans, who has been advising volunteers on how to restore a lock near Clydach.

The canal society said he helped "shed new light" on the waterway.
