Improvements to the A10 / A142 BP roundabout are required as part of the approved Lancaster Way Business Park expansion planning application. They will not only improve capacity to tackle the additional traffic, but will benefit people by providing more than 2,500 new jobs.
As this is a vital development to support economic growth within East Cambridgeshire and expected to generate 2,500+ jobs, 75% of which are expected from the local area, we agreed to assist in developing a solution as it became apparent that it was a more complex scheme than first anticipated.
To facilitate the design process, Grovemere Property (business park developer) funded a feasibility study covering the A10, BP and Lancaster Way roundabouts. The study assessed the current congestion issues against future growth which was completed in October 2018.
The outcome of the study concluded that the main cause of the capacity issues are at the BP roundabout. Any improvements here would not be as beneficial unless the Lancaster Way roundabout was also improved. No works to the A10 / Angel Drove roundabout were found to be necessary as the queues here were as a result of capacity issues at the BP roundabout.
The study identified options for each roundabout. The traffic modelling carried out as part of the feasibility study confirmed that medium-term highway improvement schemes would provide a solution. The Cambridgeshire and Peterborough Combined Authority (CPCA) are considering the long-term future changes as part of their A10 strategic transport project.
At the BP roundabout, crossing facilities for pedestrians and cyclists were reviewed during the feasibility study, such as the provision of a combined zebra and cycle crossing or a signal controlled crossing. However, due to the strategic nature of this junction and current and future traffic capacity requirements, a 'grade separated' solution is required. This means a segregated facility not at the same level as the road, ie a bridge or an underpass. Improvements for pedestrians and cyclists at this location therefore require significant investment.
The provision of a grade separated crossing could not therefore be expected to be funded by the developer as part of the section 106 contribution. However, it is identified in the draft Local Transport Plan that specifically references provision of an improved route for pedestrians and cyclists to cross the A10. This is already being considered by the Combined Authority as part of their A10 strategic transport project. You may have seen reference to this already through their virtual information room, available to see on the CPCA website.
We have worked with the following stakeholders to develop a scheme at the BP roundabout:
- Cambridgeshire and Peterborough Combined Authority (CPCA)
- East Cambridgeshire District Council
- Grovemere Property (business park developer)
- Local elected member
Work started at the BP roundabout on 14 July 2020 and is planned to be complete by the end of November 2020.Work will take place between the hours of 7am and 4pm and we will monitor traffic levels in the area during the works.
We will provide information and a map about the work to local residents and businesses.

The A10 / A142 BP roundabout scheme is being funded by Grovemere Property and the Combined Authority. The scheme is estimated to cost up to £1.8 million.
- Improvements at the BP roundabout consist of widening all the approaches to the roundabout giving two lane entries and also the A10 and A142 exits for merge lanes.
- The eastbound arm of the A142 will have three lanes giving a dedicated left turn lane onto the A10 north.
- The exit of the A10 services will be restricted to left turn only. Any vehicles wishing to head west will have to go around the roundabout.
Temporary arrangements during construction
- To facilitate the works, the eastern leg of Witchford Road is going to be closed for the duration of the works and will act as the site compound.
- As a large proportion of the works are in front of the A10 services, pedestrians will be diverted via a temporary footpath on the south side of the A142 with temporary traffic lights to cross over the A10 and A142.
- The roundabout will be under three-way temporary traffic lights 24/7 for the duration of the scheme, meaning delays are possible.
- At the end of the programme, there will be five nights of full road closures for the resurfacing and road markings. The scheme is programmed to start on 14 July 2020 and is planned to be complete by the end of November 2020.
