Balfour Beatty joint venture progresses UK’s largest road upgrade

5 July 2017


New aerial photographs show the progress on the A14 project, the biggest road upgrade under construction in the UK. The A14 is being delivered by a four-way joint-venture comprised of Balfour Beatty, Carillion, Skanska and Costain.

Work on building the £1.5bn upgrade to the A14 between Cambridge and Huntingdon started in November last year. The project includes widening a total of seven miles of the A14 in each direction (across two sections), a major new bypass south of Huntingdon, widening a three-mile section of the A1 and demolition of a viaduct at Huntingdon, which will support improvements in the town.

Alongside the emergence of this new road, foundations and bridge columns for some of the project’s 34 new bridges have been installed.

The project’s earthworks team have been stripping top soil over more than 17 miles out of the project’s total length of 21 miles to create several sections of the future new road including: the Huntingdon bypass, the new Swavesey junction, and the five-mile long local access road, which will link local communities between Huntingdon and Cambridge without the need to use the A14.
