A market town's traffic is set to be thrown off kilter for the next four weeks amid the biggest shake up of its gas supply in decades.
And businesses in North Walsham might be in line for compensation if they lose trade due to the works, which will involve replacing gas pipes below the town centre.
A North Walsham Town Council spokesman said the main vehicle entrance to the high street - the Aylsham Road/Cromer Road/Mundesley Road junction - would be out-of-action, and traffic would be reversed.
The spokesman said: "Traffic is likely to be more chaotic in North Walsham for the next few weeks.
"Access [to the town centre] will be from Church Street only.
"During this period Market Place traffic will be reversed, entering from Church Street and exiting into Kings Arms Street."
Engineering firm Triio is carrying out the works in partnership with gas network operator Cadent.
Triio said shops - which will be open as usual throughout the works - could claim money back if they lost out.
It said: "If you own a business in the area which you feel may have been affected by the work we need to do, you may qualify for compensation if you rely on customers visiting your business premises for usual trade to take place."
