The A43 which links Kettering and Northampton is set to benefit from millions of pounds of Government funding to improve a congested junction.
The Round Spinney roundabout, which connects the A43 to Kettering with Talavera Way, Booth Rise and Lumbertubs Way just north of Northampton, is in line from a £2.1 million Department for Transport (DFT) boost. The total cost of the scheme has been estimated at £3.4 million.
The money will also help prepare the road for a new 2,000-home development adjacent to the road.
The funding is one of a number of measures announced by Transport Secretary Patrick McLoughlin, and came after a bid from Northamptonshire County Council was submitted in October 2013.
In its application to the DFT, the authority said: “The A43 links the three largest towns in Northamptonshire: Northampton, Kettering and Corby, all with substantial plans for growth.”
It said more than 27,000 vehicles used the road between Kettering and Northampton every day, adding that the approaches to Northampton were the most congested.
Mr McLoughlin said: “Whether it’s unblocking bottlenecks on local roads, improving trouble spots on our motorways and trunk roads, or working to deliver better railways through electrification, these projects will benefit communities up and down the country and help keep Britain moving.
“By investing in our local and regional transport infrastructure we can help support new jobs and boost our overall competitiveness in the global economic race.”
