Balfour Beatty has been chosen for the A21 dualling between Tonbridge and Pembury.
Advance work on the £69.7M project is expected to start this autumn, with construction commencing in spring 2015.
The 4km section of the A21 between Tonbridge and Pembury in Kent will be upgraded from single to dual carriageway, adding a lane in each direction, upgrading junctions and improving the road layout.
Stephen Tarr, Balfour Beatty’s managing director for major projects, said: “We are delighted to have been awarded this contract to upgrade the A21. Our commitment to building sustainably, engaging with local stakeholders, and employing a local supply chain is key to our success and we aim to leave a lasting legacy as a thoughtful contractor behind us.”
Highways Agency project manager Graham Link said: “The A21 is a vital link between London and Hastings as well as connecting local towns. Providing better infrastructure will help the local and national economy, helping to support businesses and creating jobs.”
Today’s announcement follows successful completion of all the statutory planning procedures.
