The Busiest UK Roads and Regions have been revealed in a new study.

Lancashire’s drivers spending more than two hours in traffic on average.

Car Sloth, an EV subscription comparison site, commissioned a study into the UK’s traffic congested areas. It analysed average traffic delay times from official government data.

With London included, the capital dominated the most congested league, occupying 9 of the 10 top spots (unsurprisingly!).

The Busiest Roads in the UK

A2010, Brighton and Hove

The A2010, which connects Brighton’s two main east-west routes with Brighton Station, was the busiest road in the UK (apart from London), with an average SVPM of 18.6 minutes. Brighton and Hove Council introduced a low emission zone back in 2015 and is hoping to introduce an Ultra Low Emission Zone in the future.

A3039, Bath and North East Somerset

The A3039, which connects two of Bath’s main roads around the East of the city centre, was the second busiest road in Britain, with drivers racking up an average SVPM of 14.5 minutes. Bath introduced a Clean Air Zone in the city centre in 2021, but it does not apply to private vehicles, only buses, coaches, taxis, heavy goods vehicles and vans.

A203, Brighton and Hove

Third on the list of most congested roads was the A2023, an urban A Road in Brighton and Hove with an average SVPM of 13.2 minutes. Brighton was named the second most congested city to drive in after London and is home to some of the country’s slowest roads. The Council in Brighton prioritises safety over speed – many of the city’s A Roads have a speed limit of 30mph – and public transport over private vehicles.

Further findings

  • Brighton and Hove found to be one of the busiest traffic areas

  • Lancashire county has the heaviest traffic, but no current Low Emission Zone or similar

  • London drivers face 88% increase in travel delays compared to rest of UK regions
