A LEGAL challenge has been launched against £1.5 billion plans to turn parts of the A66 into a dual carriageway.

The A66 Northern Trans-Pennine project will dual the 80-kilometre stretch between Penrith and Scotch Corner in North Yorkshire. 

It was approved by the Transport Secretary on March 7, following a delay in the decision. 

Transport Action Network (TAN) has launched a legal challenge as they believe that the Secretary of State's decision was "flawed".

Chris Todd, TAN’s founder and director, said:  “The £1.5 billion A66 Northern Trans-Pennine represents very poor value for money and will cause great harm to important landscapes and wildlife.

"At a time when we are experiencing more flooding due to climate change, it will drive up carbon emissions by 2.7 million tonnes.

"By encouraging more HGVs it will also make the existing parts of the A66 that are already dualled more dangerous. 

“We believe the Secretary of State has not considered these issues properly, gambling away £1.5bn of taxpayers’ money in the process.

"National Highways should instead be implementing cheaper and quicker safety measures on this road, for a fraction of the cost and without harming the environment or taking us backwards on climate," he said.

National Highways project director Stewart Jones said: “The A66 is a key route in the north of England and helps connect Cumbria with Durham.

"The route currently suffers from heavy congestion and has a poor collision record.

"We believe our proposals will provide smoother and safer journeys for thousands of commuters, hauliers and drivers who use this vitally important route every day, while also delivering an economic boost to the North," he said. 

National Highways have said they will fully support the legal process as the challenge passes through court. 

Archaeological investigations and preparatory works including utilities diversions will continue during 2024.
