Work to build a new A46 Dunholme/Welton roundabout will start to be built next month, with the road closed until September at least.
Construction is scheduled to start on Monday, July 20 and could take up to ten months to complete, so long as the weather holds up.
Over 11,000 vehicles use the A46 every day, so the decision has been made to increase the road’s safety in the long run.
Along with the T-junction conversion into a roundabout, work will also be done to reduce the hill along that section of the road by two metres for better visibility.
From beginning on July 20, through to Wednesday, September 2, the A46 between the Welton Road / Lincoln Road junction near the garage and car wash, and the A46 / Lincoln Road junction entering and exiting Dunholme to the south, will be closed.
This section of road will be closed 24 hours a day, 7 days a week, with a diversion route via the A15 / A631 / A46 and vice versa.
Councillor Richard Davies, executive member for highways and transport at Lincolnshire County Council, said: “As it is now, this junction is an accident hotspot.
“Nearly twenty road traffic collisions have resulted in injury over the past five years, along with many other non-injury collisions.
“Not only will these changes help improve safety and reduce congestion, but they will also support future development in the area.
“These works will inevitably cause some disruption, but we’ll be doing our absolute best to keep traffic moving while this stretch of A46 is improved.”
