Scotland Gas Networks (SGN) began work on an ‘essential’ £250,000 upgrade of the gas pipe network in the Bonhill Road area on Sunday, and bosses say teams will operate ‘extended hours’ to ensure the project runs on time.

However, residents living nearby are concerned extended hours may cause noise pollution.

Their concerns were heightened after roadworks carried out last week — not thought to be related to the gas project – began at 10pm, prompting complaints children living on Dumbuck Road were being kept awake.

One mum, who asked not to be named, told the Reporter: “I phoned the council to see how I could complain. I have two kids who woke up a number of times through the night. I understand roadworks need to be done, but children need their sleep. Why would you start roadworks at night? Its ridiculous.” But SGN has moved to allay fears, insisting no work will go on after 7pm.

A spokeswoman told the Reporter: “We appreciate that roadworks can be frustrating and would like to apologise for any inconvenience caused.

“We will be working seven-days-a-week, between 7am and 7pm, to ensure our essential work at the junction of Stirling Road (A82) with Garshake Road and Round Riding Road is completed as quickly as possible. We are mindful of local residents and will try to minimise noisy activities where possible.” Phase one of the project will run approximately from October 12-19, on the inside lane, with north bound closed at Round Riding Road junction.

Phase two will begin around October 20-26 with the outside and right turn lanes closed on both carriageways.

Phase three is expected to run from October 27 till November 2, with the inside lane on south bound closed at Garshake Road junction.

The gas works are the second major project to begin in the area recently, with Scottish Water currently working on the adjacent Round Riding Road.

One worker on site laying water pipes told the Reporter they hope to be completely finished by early December, weather permitting, while the gas works takes place simultaneously.

Commenting on the works, a spokeswoman for West Dunbartonshire Council said: “October 20-26 in particular will be highly disruptive and experience would suggest minimum delays of 30 minutes at non-peak times, and more during rush hour.” Dumbarton and Vale MSP Jackie Baillie told the Reporter previously: “Clearly this is a very busy junction in a residential area so there will be limited scope for night-time working.

“I would encourage Scotland Gas Networks to continue its dialogue with the community, police and the council to make sure the work is completed as quickly as possible and with the least possible disruption for motorists and residents.”
