New diversions are being put in place around a £34 million road project in Northamptonshire.
The current contra-flow arrangements on the A6003 are being altered, to allow the completion of a roundabout to mark the starting point of the four-mile A43 Corby link road.
The changes will start on the evening of Saturday, July 20 and will be operational from the morning of Sunday, July 21 for a period of about eight weeks.
This next phase of the works will establish the contra-flow on the southbound carriageway of the A6003.
People travelling north from Kettering to Corby, will be diverted off the northbound carriageway at the southern crossover and into contra-flow on the southbound carriageway. They will then use part of the new roundabout and then be taken back on to the northbound lane of the A6003 at the Rushton Turn.
Those travelling southbound from Corby towards Kettering, will be restricted to the inside lane north of Barford Bridge, then around the new roundabout and back on to the southbound carriageway which will still be in contra-flow.
Cllr Andre Gonzalez De Savage, cabinet member for infrastructure, said: “Nobody can have failed to see the progress of the new road, especially the new roundabout at Barford Bridge taking shape.
“This next phase of the traffic management on the A6003 will allow the completion of the roundabout and I would urge all road users to be patient throughout the duration of the works, but to be especially careful when the new contra-flow arrangements are put in place as there is bound to be some congestion.
“This is a vital piece of work on a very busy road, and we need everyone to continue to play their part in keeping both drivers and the workers safe.”
