Costain has been appointed by Highways England to deliver two of the three sections of the A14 Cambridge to Huntingdon Improvement Scheme that will see £600 million worth of work.

The Costain joint venture with Skanska has been awarded Package One, covering the A1 junction at Alconbury to the East Coast Mainline and Package Two covering east of the East Coast Mainline to Swavesey.

The A14 Improvement Scheme is required to enhance the capacity and reliability of the UK strategic road network in order to ensure better journeys for road users.

Stretching over 25 miles, the works will improve this highly congested stretch of road. Initial design work will commence immediately with the development of detailed plans for the delivery phase, which will commence in late 2016.

The road will be open to traffic in 2020, with the works in Huntingdon town being completed after.

Andrew Wyllie CBE, Chief Executive of Costain, said: “The A14 is a strategically vital transport corridor in East Anglia and we are delighted to have been appointed to this major improvement project by Highways England.

“This appointment reflects our reputation for delivering solutions to national infrastructure needs in long-term, strategic partnerships with our customers.”
