A428 Black Cat to Caxton GibbetRecently updated

Improving the A428 near St Neots.

Region:  East
Start date:  Spring 2020
Cost:  TBC
Status:  PLANNED
Type:  Major Scheme
End date:  TBC

Progress report

We held a public consultation on the route options back in March and April 2017. We asked for views on the need for improvements to the A428, feedback on three route options and three options to improve the Black Cat Roundabout.

We are currently analysing your feedback from the consultation, together with findings from meetings with local landowners and businesses, which will help shape our decision on the preferred route in early autumn.

We have appointed locally based AECOM as our delivery partner for professional design and engineering services. This includes the development and delivery of an application for planning permission which is to be submitted to the Planning Inspectorate in autumn 2018.

We are now carrying out ecological surveys for all the route options. The results of these surveys will help inform our decision on the preferred route.

What next?

Topographical survey fieldwork has recently begun and is anticipated to continue through to early September. We are planning ground investigation surveys for sections of the scheme that are common to all route options between October 2017 and January 2018.


Date Event
August 2017 to December 2017 Site surveys including topographical studies and ground investigation at key locations for all route options.
Autumn 2017 onwards Preferred Route Announcement and further engagement with local community representatives and landowners.
Early 2018 Public consultation expected to take place on the developed route option.
Early to mid-2018 Further develop the scheme incorporating input from all consultees.
Autumn 2018 Submit application for a Development Consent Order.
Early 2020 Decision expected from the Secretary of State for Transport. If approved, construction will proceed in 2020.

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
