Viaduct complete on £1.5bn road scheme

A14 viaduct

Work on the £1.5bn A14 Cambridge to Huntingdon upgrade is gaining pace, as work on the River Great Ouse viaduct comes to an end.

The 747m long structure is the biggest bridge on the project and will take the new A14 over the river and the East Coast Main Line Railway as part of the 33km road.

The £1.5bn scheme will transform journeys on one of the East of England’s most vital roads, and the completion of the viaduct is the latest piece of the puzzle to be put in place.

Now, Highways England is sharing a time-lapse video showing the work that has gone into creating the huge bridge since it began in November 2016.

A14 construction director Willie McCormick said: “This viaduct over the River Great Ouse, south of Huntingdon, is by far the biggest bridge on our 21-mile project.

“It’s taken over 18 months to build, and covers 747m to carry drivers over the river and floodplain – yet when it opens to traffic in 2020, drivers will cross it in less than 30 seconds.”

He added: “Our hard working team is building 34 new bridges and structures as part of this epic project to deliver a new and improved A14 between Cambridge and Huntingdon for the 85,000 vehicles a day who drive it.”

Sixty-four piers have been erected to carry the viaduct over the River Ouse floodplain, each around 2m wide and embedded up to 30m in the ground. The pier support the 17 spans of steel beams and concrete slabs forming the bridge deck.

Main construction on the A14 project started in November 2016 and the road is scheduled to open to traffic by December 2020.
