Britain’s biggest road-building project, the £1.5bn A14 Cambridge to Huntingdon scheme, is opening for traffic eight months ahead of schedule.

The upgraded road was originally planned to open to traffic by December 2020, but now the last of the 24/7 roadworks have been removed and the new lanes are available for traffic, eight months ahead of schedule.

The A14 Cambridge to Huntingdon scheme will transform journeys on the A14 in Cambridgeshire, shaving up to 20 minutes off journeys and strengthen links between the midlands and the east of England – vastly improving access to and from the UK’s largest container port at Felixstowe.

Highways England chief executive Jim O’Sullivan said: “This upgrade is a key addition to our national infrastructure, better linking the north of England and the midlands to the east of England and to the Haven ports. It also brings economic benefits to the wider region and local towns and communities.

“Being able to open it more than six months early and on budget shows what the UK construction industry can achieve with an integrated client team, common goals and targets, and a shared vision of success.

“I would like to thank everyone across Highways England and our supply chain for their contribution to this project as well as road users, residents and stakeholders for their patience and support during the work.”

Highways England confirmed the work to upgrade the A14 between Cambridge and Huntingdon has largely been completed, which means the permanent roadworks have been removed and the national 70mph speed limit has been restored.

Further work in the road verges, including completing landscaping as well as cycle, horse riding and pedestrian paths, will continue. To carry out the remaining work safely, some temporary overnight closures or off-peak daytime lane closures will be needed.

Essential work on the upgrade has continued throughout the Coronavirus outbreak, with new sections of road opened as quickly as possible, to ensure vital goods were able to travel through. A number of measures were also put in place to ensure work was completed safely and in line with Public Health England’s advice. 

Work on the project began in November 2016, and has employed over 14,000 people in total, with up to 2,500 working on site during the project’s peak. Building the new road took 14 million construction hours – the equivalent of almost 1,600 years.
