Dumbarton residents are facing months of road closures and disruption as SGN upgrade the gas network by replacing old metal gas mains with new, durable plastic pipe.

The works will last for 17 weeks and from May 7, as part of phase one, Castlegreen Street and Greenhead Road will be closed at their junctions with Glasgow Road for approximately three weeks.

Local signed diversions will be in place at all times and access will be maintained for residents.

Phase two, meanwhile, will begin on Tuesday, May 28 and will last for approximately six weeks.

Glasgow Road will be temporarily closed in both directions, while Castlegreen Street and Greenhead Road will remain closed as in phase one.

Signed diversions will be in place and large advanced warning signs will also be displayed.

Resurfacing works at the junction scheduled to take place later this year, will instead take place while the closure is in place.

Finally, phase three, which begins on Tuesday, July 9, will last approximately eight weeks and will see Glasgow Road, Castlegreen Street and Greenhead Road reopened.

SGN will be working in Castlegreen Street near the fire station and temporary traffic lights will be in place during this time.

The company recently carried out multiple emergency repairs on these mains, which are located on a busy junction in the town.

Stephen Campbell, project manager, said: “We’ve worked closely with the local authorities in planning this work and we will be doing everything we can to limit disruption during our essential work in Dumbarton.

“We appreciate that roadworks can be frustrating, however, the new plastic pipe has a minimum lifespan of 80 years.

"This means once the work is completed, Dumbarton homes and businesses will enjoy the benefits of a continued safe and reliable gas supply for many years to come.”
