Work to expand the A16 roundabout at the Wardentree Lane Industrial Estate is to start on Monday May 13.
And Highways bosses have confirmed the work will be done continuously with the already started construction at the road’s junction near Springfields, less than a mile down the road.
It will be the final one of five junctions to be worked on in South Holland and Boston districts following £20m of Levelling Up funding.
Lincolnshire County Council say temporary traffic signals or night-time closures will be required to remove the traffic islands at the roundabout.
Barriers will be put up during the works and lanes narrowed, similar to the work currently being carried out at the ‘McDonald’s roundabout’.
Coun Richard Davies, Lincolnshire County Council’s executive member for highways, said: “I’m really glad to announce that we’re less than two months away from starting our fifth, and final, Levelling Up improvement scheme along the A16 – this one at the A16/B1180 Pinchbeck Roundabout.
“Not only will we be making the roundabout bigger, with the junction widened to provide two wider lanes within the roundabout, but we’ll also be lengthening the two-lane approaches and exits on the A16 North.
“And, while the road is dug up, we’ll also be taking the opportunity to install a new drainage system ahead of laying new road surfacing and installing new signage and street lighting columns.
“Like the rest of our ‘Levelling Up’ improvements, these enhancements to the roundabout will help increase capacity, reduce congestion, improve journey times, and future-proof the roundabout for A16 upgrades down the line
“It’s important to note that these works will be running concurrently with our ongoing works down the road at the A16/A151 Springfield Roundabout.
“As with any major road improvement project, some disruption on local roads is inevitable when work is underway.
“However, we’ll be doing everything we can to keep people moving and to ensure access to the nearby businesses is maintained throughout the scheme.”
