Planned improvements to the A5/A45 crossroads in Weedon are set to start today (Monday).
The changes for the crossroads will see a widening of lanes to improve journey times and ease congestion. Work is expected to take 12 weeks.
The £950,000 scheme has been funded by the Government’s Growing Places Fund, which is designed to help push forward housing and economic growth.
Leader of Northamptonshire County Council, Cllr Jim Harker, said: “This is good news for the county.
“This is one of the most important junctions in Northamptonshire and anything that can be done to improve the safety on the crossroads needs to be carried out.
“In addition it also supports economic growth in the Daventry area, which has to be welcomed, particularly as the UK economy moves into recovery.
“It in no way diminishes, however, the need for the Flore, Weedon, Nether Heyford bypass and the council is working hard to bring this major scheme forward as quickly as possible.
“The Growing Places Fund was established for schemes such as this and I’m delighted that we’re seeing results, right here in Northamptonshire.”
The work will include extending the carriageway, creating additional lanes and installing ‘smart’ traffic lights to improve traffic flows.
Paul Southworth Chairman, Northamptonshire Enterprise Partnership, said: “The junction is part of a key route between Northampton and Daventry and represents a major step forward in easing congestion and supporting new development.”
Northamptonshire Enterprise Partnership manages Northamptonshire’s £5.8m Growing Places Fund through which this scheme was funded.
