The project will deliver a dual carriageway A46 bypass to the west of Newark (the A1 is the to the east), providing two lanes in each direction, between the Farndon and Winthorpe junctions.
Works will also include the construction of a new five-arm roundabout at Winthorpe and traffic lights at Farndon junction to improve traffic flows during peak hours.
A new bridge will be built over the A1 where the two roads cross, to the north of the town, and a flyover installed at Cattle Market.
Total project costs are estimated by National Highways at between 拢400m and 拢500m. Skanska鈥檚 contract is worth 拢345m.
The A46 Newark bypass connects the M1 and Leicester to the A1 and central Lincolnshire.聽 It is used by 17,000 motor vehicles a day.
Skanska will begin design works in 2022. Subject to development consent being granted, construction work on site is planned to start in 2025 and the scheme is expected to open for traffic in 2028.
National Highways senior project manager Phil Boffey said: 鈥淲e鈥檙e delighted to have reached a major milestone in the development of the A46 Newark Bypass with the appointment of Skanska to deliver this much-needed upgrade.
鈥淭his scheme will bring relief for the communities enduring the current congestion as well as drivers using this key trade corridor.
鈥淲e are determined to ensure that, as far as possible, the improvements work for the community as a whole and will continue to consider the views of road users and local people as we work with Skanska in the design and delivery of this upgrade.鈥�
Jonathan Willcock, managing director of Skanska鈥檚 Infrastructure business, said: 鈥淲e have established a collaborative and trusted relationship with National Highways, with this contract building on our current projects at M42 junction 6 and the A428, where we鈥檙e constructing a 10-mile dual carriageway.
鈥淲e鈥檒l be working with National Highways and our design partner, Mott McDonald, bringing together a really strong and integrated team, alongside our wider supply chain.
鈥淲e鈥檙e taking the lead for this project from the preliminary design stage, which will enable us to more closely align design, consultation and buildability. This will help us to identify opportunities to optimise productivity, reduce cost and carbon emissions and deliver the project safely 鈥� while leaving a positive legacy for local people.鈥�
