This Wolverhampton road has been dubbed 'busiest in the UK outside of London'

A Wolverhampton road has been dubbed the ‘busiest A-road in the UK outside of London’.

Drivers in Wolverhampton are reportedly losing more than two minutes for every mile travelled, according to analysis of high traffic A-roads data by Marshall Motor Group.

The dealership used congestion data from the Department for Transport to find out where drivers face the biggest delays compared with free-flowing conditions and found that the A4150 through Wolverhampton has the worst delays outside London, adding an average two minutes and 12 seconds per mile.

The delay is around three times the median delay across the 266 high-traffic roads analysed.

However, the analysis showed the A4540 in Birmingham records around one minute and 57 seconds of extra delay.

Ben Welham, motoring expert at Marshall Motor Group, said: “For commuters, a road that regularly adds a minute or two for every mile can make a real difference over the course of a week, especially when roadworks or incidents add to the usual congestion.

“The figures also show that high traffic levels don’t always mean long delays, with some very busy roads still keeping traffic moving well.”
