A £600,000 study has been approved to explore ways to improve the A1 from its junction with the M25 all the way to Peterborough.

The Highways England project will focus on how to improve the non-motorway section linking the two parts of the A1(M) to motorway standard.

At the moment the busy route isn’t classified as a motorway between Stotfold and Alconbury, just south of Peterborough.

It is one of six studies taking place across England to address the biggest challenges facing the strategic road network and is due to be finished by the end of next year.

Consultants Arup will review existing evidence and prepare a case to consider further investment on the A1.

The study will look at bringing consistency to the southern section of the route and whether improvements, including changing the alignment of the road, could reduce the environmental impact of the existing route and benefit local communities.

Roads minister Andrew Jones said: “As part of our long-term economic plan, we are investing over £2 billion on major road improvements in the East of England.

“Today’s announcement will mean better transport links and more job opportunities for hardworking families across the region.”

Nigel Edwards, the divisional director of strategic planning for Highways England, said: “This study could lead to major benefits across the East and I’m pleased we’ve now reached the stage where we can appoint a specialist company to assess the feasibility and start the process.

“The A1 is one of our oldest trunk roads, and also one of the least consistent. This study will examine what could be done to improve the road to motorway standard and bring consistency to the southern section of the route.”

The study is due to be completed by the end of 2016.
