Lincoln's traffic bosses have pledged to keep delays to a minimum when a £3.3 million Canwick Road project gets under way next year.
Lincoln's drivers, already dogged by long-running works at Brant Road, will have to brace themselves for more agony from next October.
The scheme will see major changes to the Washingborough Road and South Park Avenue junctions and will be jointly fund by Lincolnshire County Council and the Department of Transport's Pinch Point fund.
The council is already aware of the potential disruption for drivers and visitors to next year's Christmas market, but claim the start time is not set in stone.
Les Davies, senior project leader, said: "The dates for this project are provisional and so could well change.
"If the work did coincide with the Christmas market period, we'd put measures in place to make sure it has little or no impact on traffic into the city."
The construction period for the scheme is expected to be nine months with Canwick Road seen as a key route for access to the centre and a route through the city.
It already suffers considerable congestion, especially at peak periods, and the council hopes that the new and improved road layout will help solve the problems.
To achieve their aim, the county council intends to compulsory purchase land from South Park Care Home and demolish the wall forming the front and side boundary of the building.
South Park Avenue will be widened for around 160 metres west of its junction with Canwick Road.
In total the road improvements will be more than 500 metres long and provide two lanes in each direction from Canwick Hill to the point where it forms Canwick Road north of South Park Avenue junction.
The current annual average daily traffic flows in Canwick Road between South Park Avenue and Washingborough Road are around 19,000 vehicles.
The figure is significantly higher north of South Park Avenue.
The scheme will also include a pedestrian crossing as part of the traffic-signal controlled junction as well as similar provisions for cyclists.
This follows on from a fatal accident four years ago when a pedestrian was killed crossing Canwick Hill near to the junction.
The scheme is due to be considered by the executive committee of the county council next month.
