The three-month closure of a busy Kettering road begins on Monday, December 9.
And residents are urged to make plans for a significant detour.
Major work is taking place on the railway bridge in Pytchley Road as part of Network Rail’s plan to electrify the Midlands main line from London as far north as Sheffield.
But it means motorists will have to take a diversion via Barton Seagrave and the A14 in order to get from one end of Pytchley Road to the other for three months.
However, Network Rail has also said that access over the railway bridge for pedestrians, cyclists and motorised scooters will be maintained during most of the work, although that access will also be closed from 10pm on Christmas Eve until the early morning of December 27.
A shuttle bus will be provided by Network Rail during that period.
Network Rail’s Justin Page said: “We thank people in advance for their patience and are working closely with Northamptonshire County Council and Kettering Council as we continue our plans to build a better railway for the East Midlands.”
Residents have serious concerns
People have left dozens of comments on the Northants Telegraph’s Facebook page, with others emailing their opinions in to us.
Among them was Dean Speirs, who said he understood that the work had to be done.
But he added: “It’s going to be a nightmare. I work on Orion Way and it’s bad coming out at night.
“I dread to think how it will be when the bridge is closed.”
Anna Turnbull said the timing of the closure during the festive period would be likely to cause problems.
She added: “Absolutely ridiculous when it could have waited until after Christmas.”
Chris Sanders added: “Closing a major on/off road for the town is bound to cause problems and put more strain on an already creaking and cracking road system.”
And Ben Johnson said: “Cutting off that part of Kettering from the main town without another practical means of getting across is madness.”
But others had sympathy for those carrying out the works.
One, Claire Humphrey, said: “No matter when they done this it would cause a problem and would make people rant and rave.”
