A14 Cambridge to Huntingdon

Services: Planning & Controls

Value: 1.2 Billion

Sector: Highways

The existing A14 trunk road between Cambridge and Huntingdon is well known for congestion and delays:

  • almost 85,000 vehicles use this stretch of the A14 every day; a lot more than we originally designed for
  • around quarter of this is heavy goods vehicles – well above national average for this type of road

Case for the scheme – executive summary

The economic case for the scheme – infographic


The proposals for the A14 will:

  • relieve traffic congestion
  • unlock local economic growth
  • enhance national economic growth
  • connect communities
  • improve the environment
  • improve safety and reduce driver stress
  • improve the environment in Huntingdon
  • create a positive legacy for the region

The scheme in detail


The government has made a provision for £1.5 billion of capital investment for this scheme. The proposals will be funded through a combination of contributions from Central Government, local authorities and Local Enterprise Partnerships.

Once work is complete the existing A14 will be ‘de-trunked’ between Huntingdon and Swavesey and between Alconbury and Spittals interchange. This means the road will gain county road status and Highways England will pass responsibility for the road to the local authority.

A1 widening between Brampton and Alconbury

We’ll widen the A1 between Brampton and Alconbury over approx 3½ miles, from 2 lane dual carriageway to 3 lane dual carriageway. Between Brampton and Brampton Hut we will construct a new road to the west of the existing A1. The existing A1 road becomes part of the new A14 Huntingdon Southern Bypass.

A New Huntingdon Southern Bypass

A new Huntingdon Southern Bypass, approx 12½ miles in length, will provide a 2 lane dual carriageway between Ellington and the A1 at Brampton and a 3 lane dual carriageway between Brampton and Swavesey.

This removes a large proportion of traffic from the existing A14 between Huntingdon and Swavesey as well as Brampton Hut and Spittals interchange. The new bypass will include a raised viaduct section of road running across the river Great Ouse and a bridge over the East Coast Mainline railway.

It will include junctions with the A1 at Brampton and with the A1198 at Godmanchester.

Huntingdon Town Centre improvements

We’ll demolish the A14 rail viaduct over the East Coast Mainline railway and Brampton Road in Huntingdon. A through route will be maintained broadly along the line of the existing A14 through Huntingdon, making use of the Brampton Road bridge to cross the railway line and by constructing a new link road from Brampton Road to connect with the A14 to the west.

A14 widening

We’ll widen the existing A14 over approximately 5½ miles to provide three lanes in each direction between Swavesey and Bar Hill and to four lanes in each direction between Bar Hill and Girton. Widening of a 1½ mile section of the Cambridge Northern Bypass between Histon and Milton.

A14 junction improvements

We’ll improve the capacity of existing junctions at Swavesey, Bar Hill and Girton and make sure they are compatible with adjacent proposed developments such as Northstowe. We’ll improve access and connections for cyclists, horseriders and pedestrians.

We’ll construct a new local access road, approximately 5 miles in length. This will be dual carriageway between Fen Drayton and Swavesey and single carriageway between Swavesey and Girton. This provides a route for local traffic between Cambridge and Huntingdon and access to properties and businesses along the corridor.

Development Consent Order – requirements register

We made a commitment to publish and update a register listing the requirements to be completed as part of the Development Consent Order (specified under the Register of Requirements in Schedule 2). This sets out:

  • each requirement
  • whether the requirement needs approval by the Secretary of State (or other duty holder)
  • whether any approval has been applied for or given
