Progress report

Our consultation closed on 23 April 2017; we would like to thank you for your feedback on our proposals. We are now reviewing the responses and will produce a consultation report summarising the feedback received. We will complete our assessment work then refine the options, incorporating the comments provided where it is practical.

What next?

We expect to announce the preferred route for the scheme in summer 2017. In the meantime, we will be carrying out further environmental surveys to help determine protected species and local biodiversity over a wide survey area. We will identify and address flood plain issues and associated impacts as part of these works but as yet the specific details are unknown.

Our environmental impact assessment will take into account the noise and pollution levels and mitigation measures which must be factored into our proposals. It is important to note that the location of this survey work should not be taken as an indication of where any future route might run and does not reflect land on which the final scheme may be.

Following the preferred route announcement we will be carrying out a second consultation in autumn 2017; details of how you can take part will be published in due course.

Why we need this scheme

The A428 between the A1 junction near St Neots and the A1198 Caxton Gibbet is single carriageway with a series of roundabouts and give-way junctions. It experiences major delays during peak periods, resulting in delays and reduced speeds. With few available diversions, incidents and accidents result in disruption over a wide area.

The A428 is an important route in an area of the country where considerable growth in housing and employment is planned.


The scheme will:
  • reduce congestion and delays
  • increase road capacity
  • improve journey time reliability
  • supports the growth identified in local plans
  • improve safety
  • provide alternative access to local roads
  • help the transport network to better cope with road maintenance and with incidents such as collisions, breakdowns, maintenance
  • improve the environmental impact of transport on communities along the existing A428 route
  • provide improved routes between communities for cyclists, horse riders and pedestrians
  • reconnect communities
  • improve safe and effective access for public transport users
