Progress report

From 6 March to 23 April 2017, we consulted on proposals to provide a dual carriageway on the A428 between Black Cat roundabout and Caxton Gibbet and to improve the Black Cat roundabout. This consultation was to seek your views on a range of route and junction options at an early stage of scheme development. Since the consultation, we have continued to develop the scheme by incorporating your feedback and carrying out technical assessments and surveys. We have also recognised the need to better understand the direction and incorporate potential changes from the A1 East of England Strategic Study.

We are therefore currently undertaking further analysis of planned developments in the region and the implications of any potential growth in traffic for the A428 scheme. As a result, we have not yet announced the preferred route. We recognise that this delay may be frustrating; however it will ensure that our scheme meets people’s needs locally and further afield.

Our engagement with all affected landowners and stakeholders is ongoing and we will hold a further formal consultation following the announcement of the preferred route. This will give you another opportunity to share your views and continue to help shape the scheme.

What next?

We will be continuing with surveys for sections of the scheme that are common to all route options.

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
