Where are we now?

We are making good progress on the new bridge and side roads between the East Coast main line and Swavesey. All bridges except one (New Barnes Lane) will be open by the end of the year. This will allow us to continue building the new A14 bypass where it passes underneath the bridges.

In June we switched the northbound and southbound A1 traffic south of Brampton Hut onto the new A1 carriageway. We are now working on the old A1 carriageway which will become part of the new A14.

We have also switched the eastbound A428 to travel under the new structure at Girton. This new bridge will be part of the new Girton interchange and will allow drivers travelling west from the Cambridge Northern bypass to join the A14 much more easily.

Over the next few weeks, we will finish installing the beams on the River Great Ouse Viaduct. The heaviest of the beams weighs 150 tonnes, approximately the same weight as a blue whale.

What’s next?

We have a busy autumn ahead of us.

In September we’ll be creating a temporary diversion of the A14 to the west of Brampton Hut roundabout, for both east and westbound traffic. This will allow us to continue construction on the new Ellington junction.

We’ll also be installing the new bridge deck at Bar Hill. You can read more about this below.

In October, we’ll be moving traffic onto the new temporary bridge at Swavesey, so that we can demolish the existing bridge. This will also require a full closure of the A14.

Closure of A14 at Bar Hill (junction 29)

As part of the A14 Cambridge to Huntingdon improvement scheme, we’re building an improved junction at Bar Hill.
From 9pm Friday 14 September until 6am Monday 17 September we are closing the A14 to through traffic at Bar Hill (Junction 29).

This closure will allow us to install two new bridge decks. Each deck is pre-constructed and weighs 1,000 tonnes. The work requires considerable preparation and special transportation equipment which will need to use both carriageways.

For journeys in either direction on the A14, or to and from Bar Hill, you will need to follow diversions. Read this flyer for more information. The closure ensures the safety of those using the A14 and those working on the bridge deck installation. It also allows us to complete the project in one weekend and minimise disruption.

Proposal for A14 to be reclassified as a motorway

We want the A14 upgrade to be the safest and best road it possibly can be and we now have an opportunity to make our the road even better.

By the end of this year we will ask the Planning Inspectorate to amend the road status for a specific section of our scheme – the section between Ellington and Girton – from trunk road designation to motorway.

Motorways are twice as safe as A road dual carriageways and six times safer than single-carriageway roads, so this change offers safety benefits to our already robust plans. Classifying the road as a motorway will also remove slow moving traffic (such as farm vehicles and mopeds), which will further improve journey times.

We need to do this now so that a decision is made in time for the project opening to traffic by the end of 2020. The Secretary of State for Transport will make the final decision next year following the Planning Inspectorate’s review of our submission.

We’re currently carrying out various impact assessments for the designation change and will have more information in October, when we’ll also be carrying out a series of events. These will be publicised on our website and on social media.
