Cadent Gas has provided an update on works which have left a busy St Albans road closed for nearly a month.
Maintenance on Marshalswick Lane has forced the area's motorists to take a lengthy diversion route along Sandpit Lane and Sandridge Road.
These roads would be used when travelling to and from Sandridge, Wheathampstead and Harpenden.
Businesses in the area have also claimed that the road closure has caused a sharp drop in business.
The works, which are expected to be completed by July 1, are part of a 30-year national project to upgrade old metallic gas pipes.
Today (June 29), a spokesperson for Cadent Gas confirmed: "Work is going to plan as scheduled and we expect to have that completed tomorrow (June 30).
"The road will then be reinstated and once that’s completed, it can be reopened."
Previously, the company said it is working with both national and local authorities to plan the works and manage the disruption.
The response came after Beech Road business owner, Simone Taylor, told The Herts Advertiser that customer numbers have "fallen drastically" due to the closure of Marshalswick Lane.
Simone said: "My footfall, of which I am very dependent on, has fallen drastically, and it's only week one!
"I have a lot of older customers who are given lifts to the shop, or drive, and I am sure they just turn around and go home.
"Those same customers are not computer literate, so will not be able to order online and pay the postage."
She said she only became aware of the road closure when she saw the signs, and described the communication from Cadent as "really poor".
Cadent argued the work is essential.
A spokesperson added: "We have worked closely with Hertfordshire County Council to provide the most appropriate traffic management for this work, which includes a road closure and traffic lights, along with a diversion route.
"We are very conscious of the disruption roadworks cause and hope people understand this is necessary and essential work, to ensure everyone’s safety and maintain a reliable gas supply for their central heating systems."
