Highways bosses have been urged to justify why Harborough town centre is used a diversion route during road works on the A14.
In a letter to Highways Agency chief executive Graham Dalton, Harborough MP Sir Edward Garnier said: “We all understand the need to repair the roads but diverting traffic through town centres is not acceptable when there are other available roads in the for diverted traffic to use.”
He called on Mr Dalton to justify the decision, explain what he plans to do to limit the impact of extra traffic on the town and to clarify diversion plans during future repairs.
He also urged the Highways Agency to advertise better when planning future road works.
Improvements to the Catthorpe interchange where the A14 meets the M1 - a junction used by 90,000 vehicles a day - are due to start between January and March next year.
Roadworks are also planned between junctions 7 and 9 of the A14 next month.
Sir Edward said his letter was prompted by a number of complaints from people living in Coventry Road and Lubenham Hill about the volume of lorries using the town as a through road in the evening during roadworks.
“Quite apart from clogging up the town centre these vehicles are noisy and cause unacceptable vibrations affecting people’s quiet enjoyment of the properties, their sleep and damaging the buildings themselves,” said Sir Edward.
“On warm evenings it is impossible to leave the windows open because of the noise.”
One of the complainants, who uses the pseudonym Welland Bubble when contacting the Mail, called for developers to fund a relief road for Harborough as part of the planned 1,500-home scheme north-west of Harborough.
“There will be more disturbances for residents as A14 roadworks are planned for October,” they said.
“No one should have to suffer as we do - the A14 is not a bypass for Market Harborough.”
