Work on the M1 Junction 19 Improvement Scheme near Catthorpe will start in January, Roads Minster Robert Goodwill has announced.
The £190.7 million scheme will reduce congestion and improve journey time reliability and safety by replacing the existing junction with a three-level junction.
It will improve the roads between the villages of Catthorpe and Swinford so local traffic can avoid the junction.
Mr Goodwill said: “The 142,000 vehicles that pass through Catthorpe junction every day demonstrate how important this route is.
“I am delighted to announce that construction will start in January, showing our commitment to deliver much-need improvements to England’s infrastructure.”
