Work will see the civil engineering specialist deliver major improvements to the slip roads and junction approaches near Sittingbourne and the enlargement of the Stockbury Roundabout on the A249 which passes under the M2.
Graham will be replacing the roundabout with a new flyover interchange to provide improved traffic flow on the A249.
Two new dedicated free-flowing slip roads will be created with a left turn for traffic travelling from the A249 southbound to the M2 westbound and a left turn from the A249 northbound to the M2 eastbound.
Dave Brown, Highways Director for Graham Civil Engineering, said: “Our work at Junction 5 will help create a much safer, better connected and more free-flowing motorway. Preparation works are already underway and we’re excited to begin construction work later this year.”
Chris Welby-Everard, Highways England’s regional delivery director in the South East, said: “Improving the Stockbury Interchange will bring real benefits to the drivers who use this junction daily, and it will improve the flow of traffic to provide a safer and more integrated network for everyone.
“I’d like to thank everyone for their engagement and contribution to the development of this project to date. We will now progress to the next phase, ready for work to begin in September 2021.”
