A10

The A10 Virtual Information Exhibition has now ended, but you can still view the exhibition boards here.

You can also access the individual maps of the possible routes here:

 

What is it? 


The A10 between Ely and Cambridge is a key part of the Primary Route Network in Greater Cambridge, providing the main link between the two cities and to the Strategic Road Network via the A14 Milton Interchange. The route's two-lane single-carriageway configuration experiences significant peak-period congestion and presents a notable constraint to the delivery of the 17,000 new homes and 14,000 new jobs planned for this corridor over the next 15 years. Even the substantial investment in non-car modes, analysis shows that significant queueing and delays will remain. The proposed scheme therefore involves upgrading the route to dual two-lane standard.

What are the benefits? 

The scheme will: 

  • Ease congestion levels on the A10 between Cambridge and Ely 
  • Unlock up to 14,000 new jobs at Cambridge Science Park and neighbouring innovation centres
  • Release new sustainable housing opportunities, including an additional 10,000 new homes at the new town north of Waterbeach 
  • Boost the local economy 

Why is it important? / Why do we need it?

The capacity of the A10 between Ely and Cambridge is already insufficient to support its current Primary Route Network function and so presents a major constraint on local authority plans to deliver up to 17,000 new homes and 14,000 new jobs along the corridor over the next 15 years. 

Currently, more than 18,000 vehicles use the corridor daily, with peak-period traffic congestion and network reliability issues resulting in trips taking over 45 minutes to travel the 16 miles length of the route, which is over twice the free-flow journey time. Analysis also shows that nearly 80% of tips along the route have either an origin or destination outside the corridor area, meaning that the potential market for mode-shift to local non-car alternatives is insufficient to address the significant levels of congestion. 

What are the next steps? 

Since December 2019, the Combined Authority has been working on a Strategic Outline Business Case (SOBC) for dualling the A10 and improving its junction between Milton and Ely. The business case will make sure the project is viable. This will allow us to start negotiations with the Department for Transport (DfT) about how the improvements can be funded and developed further.

As part of the project we have been looking at options to modify the A10: 

  • Increasing the number of lanes in each direction along the whole route of the current A10 (online dualling) 
  • Increasing the number of lanes in each direction along some sections of the current A10 (online dualling) and in some places adding new sections on different routes (offline dualling) 
  • Increasing the number of lanes in each direction not along the current A10 and by the way of a new road (offline dualling).

In addition, we have been looking at how to improve eight important junctions. These are:

  1. Butt Lane (Milton Park and Ride)
  2. Denny End Road
  3. Cambridge Research Park roundabout
  4. Waste Treatment Site
  5. A1123 Stretham roundabout
  6. Little Thetford - The Wyches Junction (identified for further assessment) 
  7. A142 Angel Drove roundabout
  8. A142 Witchford Road roundabout
  • We want to get your feedback on the eight route options. At this stage we are not conducting a statutory consultation. Formal consultations due to take place towards the end of this year. This is an opportunities to shape the options in advance of the stage 

If you have any questions that are not covered, please email a10@cambridgeshirepeterborough-ca.gov.uk 

With the combination of dualling and junction improvements, we are now at the short list of seven options. These are:

A. Predominantly online full length dualling, bypassing the key pinch points west of Milton and at Stretham (western bypass) and Little Thetford.
B. Predominantly online full length dualling, bypassing the key pinch points west of Milton and at Stretham (eastern bypass) and Little Thetford.
C. Offline dualling of the southern section to Cambridge Research Park in addition to the junction improvements.
D. Full length, offline dualling.
E. Maximise the extent of online dualling, whilst bypassing the key pinch points at Stretham (western bypass) and Little Thetford.
F. Online dualling of the southern section to Cambridge Research Park in addition to the junction improvements.
G. Junctions only improvements.
