The top 10 slowest motorways in the UK where drivers are forced to go an average of 25mph

THE most congested motorways in the UK where Brits are forced to crawl in bumper-to-bumper traffic have been revealed.

And it's bad news if you're travelling along the M25, with sections of London Orbital Motorway recording an average speed of just 25mph.

Recent Department of Transport figures reveal the M25 northbound near A206 junction is the slowest motorway stretch in the UK, with drivers travelling at an average speed of 25.1mph.

The average speed is calculated by taking speed data from a range of cars over a 24-hour period, meaning speeds during rush hour are likely to be even slower.

The M25 northbound near the A2 was another notorious place for congestion, with an average speed of 25.4mph.

Drivers are likely to go slow while driving on the M5, with the northbound lane near Oldbury junction 2 and southbound lane near West Bromwich intersection having an average speed of 26.7mph and 27.2mph respectively.

Brits commuting along the M4 could also run into heavy traffic, with three sections of the motorway ranking in the top ten slowest.

These include the westbound lane near Chiswick junction 1 and junction 2.

Other frustrating routes for drivers include the M67 near J1, M5 northbound between J3 and J2 and M5 southbound between M6 and J1.

Recent data by transport data experts Inrix reveals motorists spend an average of 178 hours in traffic, the equivalent of more than nine days.

Rod Dennis, spokesman for the RAC, said: "As these figures show, drivers will be lucky if they can drive anywhere approaching the national speed limit on some of England’s most congested stretches of motorway.

"While some are notorious and seemingly permanent bottlenecks, others are likely to be caused by long-term roadworks which means drivers will have to hope that journey times will drop when they’re finally lifted.

"Drivers tell us that they are becomingly increasingly dependent on using their cars, so it’s vital that investment in our motorway network is maintained.

"Worryingly for drivers, we have seen evidence that some work to reduce traffic at pinchpoints on the motorway network has actually had the undesired effect of making congestion even worse, not better.

"Clearly, tackling congestion on the UK’s major roads is never a quick or straightforward task, or for that matter, cheap."
