WORK to upgrade gas mains in Hemsworth began this week.
Northern Gas Networks began replacing old cast iron gas pipes on Station Road on Monday, July 23.
The pipes are being replaced by more durable plastic pipes to safeguard local gas supplies for future decades.
The engineers from Balfour Beatty will also be working on Hall Farm and Cottam Croft.
A one-way system and diversion has been put in place while this work is carried out.
The work is expected to last for seven weeks.
