As part of an £800 million gas main replacement project, over 200 metres of gas pipes on The Strait and Danes Terrace are being renewed.
National Grid began earlier this week to upgrade a gas mains which is designed to keep homes and businesses in Lincolnshire connected for over 80 years.
The existing iron gas mains are being replaced with heavy-duty modern plastic pipes as part of the four-week project.
Leigh Allmond, a subcontractor for National Grid, works on a team of four on the project and told the Echo that the works will run from Ego clothes shop at the bottom of The Strait, up to Jew’s House before turning down Danes Terrace up to the Usher Art Gallery.
Mr Allmond said: “It’s because National Grid are running a gas replacement programme at the minute.
"They prioritize which areas get done first by the amount of leaks in certain areas, and this area has been quite bad for it.”
He said the subcontractors will try to keep their working area as tidy as possible.
“Hopefully there’s only going to be probably about six or seven more excavations up to Jew’s House.
"We should be putting the pipe in on Tuesday next week, so the area from Yak Clothing to Jew’s House will all be reinstated and it will all be back to normal, and then we’ll start on Danes Terrace,” he said.
“We’ve been allocated four weeks to do it, but we’re hoping to do it in two.”
Richard Baxter, owner of Goodies Traditional Sweet Shop, is the chairman of the Bottom of The Hill group, which represents businesses on The Strait and lower Steep Hill area.
Mr Baxter said: “It’s only just started actually, it’s not too bad, I think they’ve got all of the signs in the right place, it’s that people are going to have to excuse the noise really, we’ve got about a week of it here, and then it goes around the corner, so it’s only around 10 days that we’re going to be affected.
“But hopefully, if it’s well sign-posted, people will still walk up.
“When we had a meeting with National Grid and the City of Lincoln Council, our important worry was whether they put the cobbles back down the way that they found them, because this is the tourist attraction of Lincoln, it’s the Cathedral Quarter, so it’s got to be right.”
David Hencke, partner at Yak Clothing on The Strait said: “The main concern is that they’re hopefully going to tidy up the expensive paving that was recently put down, what they’ve left so far doesn’t look so good, but I’m hoping that’s more of a patch up and they will restore it to its former glory.”
National Grid Authorising Engineer Paul Martin said: "We appreciate that our work can cause disruption, so we will be making every effort to minimise inconvenience to the local community.
"We are working in a historical area. Where there are cobbled streets the cobbles will be carefully removed and then returned once the new pipe has been installed.”
