Gas distribution company SGN began work to replace old metal gas pipes in Hamilton Road last year and on Monday will start work on the final phase outside Motherwell Library.
At the start of the work Hamilton Road’s junctions with High Road and West Hamilton Street will be closed meaning to access to and from the cross.
It is intended that as the work carries on the lane heading towards the cross will be opened back up.
SGN hope to have the work completed in three weeks, but the closure order could be place until Sunday, August 6, if necessary.
SGN spokeswoman Hannah Brett said: “We’re now returning to complete the final phase of this project, which will see us upgrade our network outside the library.
“To minimise disruption, we’ve planned with the local authority to carry out this phase during the school summer holiday as the roads are traditionally quieter at this time of year. We’ll also be working extended hours during the week and at weekends to complete this final phase as quickly and safely as possible.
“To ensure everyone’s safety around our work area, we need to temporarily close Hamilton Road between Avon Street and the West Hamilton Street roundabout for approximately three weeks from Monday, July 10. We appreciate that roadworks can be frustrating and we thank Motherwell residents and road users in advance for their patience and understanding as we upgrade our gas network. This essential work will ensure a continued safe and reliable gas supply to local homes and businesses for many years to come.”
Signed diversions will be place to take drivers round the closure.
