Norfolk County Council has selected Costain to finalise the detailed design and build of the West Winch Housing Access Road scheme near King’s Lynn, Norfolk.

The new 2.4km road (rendered image above) will connect the A47 with the existing A10 to serve up to 4,000 new homes planned for the new Growth Area south of King’s Lynn.

Once opened, the new road will become part of the A10.

In addition to designing and building the road, Costain will provide new roundabouts to access to the new housing areas, a cycle path alongside the new road as well as dualling around 1.5km of the A47 trunk road.

“The contract with Costain is a significant part of the overall £122M project,” said the infrastructure solutions company.

“Detailed design will commence this year, with construction anticipated to start in 2027.”

Costain road sector director Andy Denman said: “This award is built on our long-established highways delivery expertise and our proven track record in delivering best-in-class, value-for-money services for local authorities across the UK.

“The West Winch Housing Access Road is an exciting project that will significantly improve people’s lives and help support the local economy.”

Norfolk County Council lead director for infrastructure Grahame Bygrave said: “Our project team will work closely with [Costain] to continue to move this project forward and progress to the start of construction as soon as possible.”
