The £3m scheme, which will start on Tuesday April 6, will see the A15 Cranwell junction and a five-mile stretch of A15 between Navenby and Brauncewell completely rebuilt.
The road had generated a series of complaints due to numerous large and dangerous potholes opening up on the stretch as the road surface began to fail, causing damage to vehicles.
All of the works will be carried out overnight from 7pm to 6am, Monday to Friday, says Lincolnshire County Council.
Steve Brooks, Senior Project Leader for Highways Infrastructure, said: “The harsh cold and wet weather we’ve had since Christmas has caused multiple potholes to form very quickly on this section of the A15.
“We had been planning to carry out this scheme in early 2022, but as a result of the rapid deterioration, we’ve accelerated our efforts to bring this resurfacing project forward by a year so long-term repairs are made sooner rather than later on this important stretch of road.
“This will be a massive project that will involve excavating over five miles of the A15 and replacing it with 22,000 tonnes of new tarmac and road material.
“The scheme will be carried out in two phases, with the team tackling the worst areas first.”
The first phase of work will be broken down into smaller sections and include rolling road closures between these areas until July:
○ Green Man Road to Navenby Heath
○ Navenby Heath to Gorse Hill Lane
○ Gorse Hill Lane to Navenby Lane
○ Navenby Lane to Slate House Farm
○ Slate House Farm to the B1191
○ B1191 to the Brauncewell quarry
The diversion route for the first phase of works will be via the A607 and the B1178.
The second phase of work will be rebuilding the A15/B1429 Cranwell junction. Work on this section is expected to start in July for approximately two weeks (details are still being finalised and will be shared closer to the time).
Mr Brooks continued: “The A15 between Lincoln and Sleaford is one of the county’s busiest stretches of road, so we’ll be doing everything we can to keep disruption to a minimum. This includes carrying the works out overnight and opening the road back up as normal during the day when it’s safe to do so.”
He also reassured drivers that the ongoing roundabout upgrade works at Holdingham with not compound the issue as the A15 work will only be at night.
“These works will also dovetail with our improvements at Holdingham Roundabout meaning our progress further down the A15 won’t be affected.”
