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? 

In Summer 2019, the Cambridgeshire and Peterborough Combined Authority is bidding for funding through the Large Local Majors (LLM) investment programme run by the Department for Transport.

While awaiting the outcome of that funding bid, the CPCA will begin to develop the Strategic Outline Business Case for the A10 Dualling scheme. This will enable the CPCA to react quickly if the bid is successful; and place the Combined Authority in the best possible position for future funding if the bid is not.
