I understand that the main reason for the delay is that they cannot easily bring heavy plant in due to a gas main
being too close to the surface of the track and the contractor (Land & Water,not Kier) is afraid of damage to same.
Do not take this as gospel,just what I have been told by people with more local knowledge than me !
I personally am very pleased that they have stopped the work, our boat club has an event at Wrenbury at Easter and after
the events of 2018 we were very concerned that the date of 29.3.2019 would not be met.
