A busy route into and out of Wellingborough will close for three hours tomorrow morning (Thursday) for surface dressing works to take place.
Weather dependant, Northampton Road will close from the A509 Park Farm Way roundabout to the Queensway/Kingsway crossroads from 5am to 8am.
The route will close to allow highways workers to carry out minor repairs the road.
A spokesman for Northamptonshire County Council said: “Surface dressing involves hot tar being sprayed on to the road surface and overlaid by chippings which are rolled on to the surface.
“When the tar cools it sets and holds the chippings to the surface of the road.
“Surface dressing is recognised as a cost-effective way of preserving and extending the life of highways.
“This prevents the disintegration of the road surface and seals the surface of the road against ingress of water to protect its structure from damage.
“The process creates loose chippings and as a result traffic is slowed to 20mph to reduce the danger of partially embedded chippings flicking up in the first few days.”
