Motorists have been warned that a main route leading from Bellshill to Coatbridge and the A8 will be closed for as long as eight months.
It’s to allow upgrading work at the Shawhead interchange, part of the M8 improvement project.
Drivers heading to Coatbridge or to Glasgow or Edinbugh via the A8 will be unable to use North Road. They face a detour via Gartcosh Walk, Bellziehill roundabout and the A725 Bellshill bypass.
The road will be open in the other direction.
A Transport Scotland spokesman said: “Our contractor is working closely with the local authority to develop a solution which will ensure that traffic restrictions will be kept to a minimum. The diversion duration has yet to be confirmed.”
The eight-month warning was given when officials briefed members of North Lanarkshire Council’s Bellshill area committee.
Bellshill councillor Harry Curran admitted drivers face ‘major upheaval’ to add to the disruption they already have two miles away at the Raith interchange.
The M8 and M74 improvement projects are running simultaneously and are not due for completion until spring 2017.
Councillor Curran said: “The problems are doubled in this area with the roadworks already taking place at Raith. I have sympathy with people working in Coatbridge or trying to get on the A8.
“However, I think there will be big benefits to Bellshill and the wider area when it is completed.”
Further information regarding the proposed works will be made available in advance via the Traffic Scotland and Transport Scotland websites.
