The UK's 20 'most dangerous' roundabouts – 14 are in the same city

There have been a jaw-dropping 287 recorded incidents at the roundabout over a decade, making it the most deadly of any in the country. 

The busy roundabout is one of the most popular in the capital and connects routes such as the A4 and A219 with the Hammersmith tube station.

The Redbridge Roundabout in East London came in next in what could be a major blow for motorists living and working in the capital city. 

According to the analysis, the roundabout which connects the A12 and A406 in Ilford has seen a whopping 284 incidents over the period of time analysed. 

The Crooked Billet interchange located next to Walthamstow Ambulance Service in Waltham Forest was listed in third place, with 252 recorded accidents. 

Staples Corner in North London was fourth with 221 incidents, followed by the roundabout at Hyde Park Corner. 

The popular tourist destination is always packed and has seen a hefty 213 incidents over a 10-year period. 

The Portsbridge Roundabout in Chichester was sixth – and crucially it was the first in the list to be located outside the capital.

The roundabout connects the M27 to the A27 but has seen motorists caught up in 205 accidents. The Mar Dyke Interchange in Essex, East of England came in next with 192 accidents.  

This was followed by the Bull Bridge Roundabout in London with 186 incidents and the Bean Interchange in Kent where there were 184 crashes in the time span on which the analysis focused.

The Old Street Roundabout in Central London rounded out the top 10 with 181 incidents recorded between 2010 and 2020. 

However, the data was collected before a massive reconstruction of the roundabout and the tube station which could have an impact on future results.
