The government has been urged to scrap the A66 dualling scheme between Scotch Corner and Penrith over concerns about the "staggering" costs involved with the project. 

Work had been expected to start in early 2025 on upgrading the notorious 50-mile stretch between Scotch Corner and Penrith to a full dual carriageway after the project was approved in March by the then Transport Secretary.

Supporters of the road have said that road safety, faster journeys, and less congestion are all reasons why the upgrade should go ahead. 

But transport campaigners have now urged the government to scrap the A66 project in favour of more spending on public transport.

Michael Solomon Williams, from Campaign for Better Transport, said: “The Government should revoke the planning order for the A66 scheme and instead use the staggering £1.4bn to maintain existing roads and expand local public transport, especially into the Lake District National Park where road traffic is already causing havoc.

"It’s an established myth that building new roads eases congestion.

"It is wiser economically and environmentally speaking to invest in public transport.”

It is still ongoing, while a legal challenge against the A66 project planning approval begins at the High Court on October 23.

The A66 Northern Trans-Pennine Project is opposed by a campaign group called Transport Action Network.

It has launched a legal challenge on environmental grounds to the planning consent granted last year by the Conservative Government.

Richmond and Northallerton MP and former Prime Minister Rishi Sunak had previously said that any delay or abandonment of the A66 upgrade in North Yorkshire could cost lives and hold back the economy.

“Twelve people died on the road in 2023 and the route has 50 per cent more casualties than the average for a road of this type,” he said. “The remaining single carriageway stretches – like the one near Ravensworth – are very dangerous and need to be dualled.

“The road’s high accident rate doesn’t just cost lives and cause many casualties, it costs businesses millions."

It is a dangerous road causing many accidents."
