The stretches of Cornwall's roads you should steer clear of to avoid getting caught in traffic have been revealed in new figures.

The Department for Transport has released its latest statistics on average speeds and delays on England’s major routes.

With the data showing that traffic is becoming more sluggish across the nation, the RAC says drivers will be frustrated but not surprised.

According to the figures, drivers in Cornwall travelled at a mere 40.1 mph on average on part of the A30 eastbound between the A394 at Long Rock and A3074 near Hayle in 2019 – the lowest speed recorded on any section of major road in the county.

This was a slight increase from the average of 39.6 mph a year earlier.

At the other end of the scale, the points in Cornwall where the fastest traffic was recorded were:

A30 westbound between A388 near Launceston (Central) and A388 near Launceston (west)

A30 westbound between A388 near Launceston (East) and A388 near Launceston (Central)

A30 westbound within the A388 near Launceston (west) junction

Motorists sped along part of the tarmac here at an average of 62.4 mph.

The figures also show that road users faced the longest delay in the same section of road where the lowest speeds were recorded.

They were held up on part of this by 25.0 seconds per mile on average, compared to the pace they would have made if travelling at the speed limit.

Across England’s major roads, the average speed was 58.8 mph last year, down from 59.4 mph in 2017.

Meanwhile, delays crept up over the period to an average of 9.5 seconds per mile.

RAC spokesman Rod Dennis said: “Drivers will find it frustrating, but perhaps not surprising, that average speeds on England’s major roads are reducing.

"RAC research shows that in many parts of the country drivers are becoming more, not less dependent on their cars for the journeys they need to make, and it’s also the case that the network is now carrying record levels of road traffic.

"If you also factor in the impact of roadworks currently affecting so many busy stretches, such as on the M1 and M4, you have the perfect combination of conditions that will lead to slower traffic speeds.”

A DfT spokeswoman said: “This government is determined to improve journeys for all motorists, which is why we’re investing nearly £29 billion to reduce congestion on our roads up to 2025.

“Looking to the future, our £2.5 billion Transforming Cities Fund will help develop innovative public transport projects, while the tripling of our investment per head in cycling and walking since 2010 is encouraging people to try other ways of getting around – helping create less congested towns and cities.”
