 Local volunteers under the guidance of the Manchester Bolton and Bury Canal Society have for years worked on sections of the canal , removing overgrowth and tidying up its general appearance . A new pedestrian footbridge , designed by artist Liam Curtin , was opened at Nob End Locks in April 2013 . Made entirely out of scaled @-@ up pieces of Meccano , it was built by society volunteers and other members of the public at a cost of about £ 90 @,@ 000 . Toward the end of 2015 , work began to restore water to the top lock at Nob End . Infill beneath the first bridge on the canal 's Bolton arm was excavated , exposing the towpath for the first time in decades .
