A study confirms what we probably already knew – the M25 is Britain’s slowest motorway

Average speeds on the M25’s circular route around Greater London are the slowest on any UK motorway, according to a new in-depth study of British traffic.

It will come as no surprise to frequent users of the motorway that drivers on the notoriously congested loop will travel at an average of just over 25mph – 45mph slower than the 70mph speed limit.

At this speed, it takes an average of five hours to complete the full 117-mile circle.

The analysis was carried out by tracking firm Satrak, which gathered data from the full 2,173 miles of motorway network in the UK during 2016. More than half a million vehicles were involved in the study.

Dan Walton, the managing director at Satrak, said: “It’s little surprise to find that the M25 is in fact the slowest motorway. We undertake work throughout the country and usually find the M25 to be the most cumbersome, and our data provides evidence for that. I’ve heard of tailbacks stretching 12 miles in my time there so it’s of little surprise to me.”

The M4 between London and Wales, also notorious for delays, came second with speeds averaging just over 30mph.

The title of third slowest went to the M606, which heads into Bradford, where cars travel at a comparatively lightning-fast 41.7mph.

Surprisingly, Cambridge topped London to be crowned the area with the slowest city traffic in the UK. Motorists in the historic university city travel at an average of just 13.73mph.
