Where is traffic expected on M25 this summer?
Transport analytics company Inrix believes the M25 – London’s orbital motorway – could see some of the worst jams due to the summer getaway, singling out the stretches between Bromley and the Dartford Crossing; Maple Cross and the M3; and the M23 to the M40.
Why could there be traffic?
With most schools in England and Wales breaking up for summer this week, the RAC said an estimated 18.8 million leisure trips are planned in the UK between Friday and Monday.
That is the most since the company began tracking summer getaway numbers in 2014.
There is also potential for fuel protests this weekend.
What are the fuel protests?
Fuel price protests are set to make traffic jams even worse during what is expected to be the busiest summer getaway in at least eight years.
Avon and Somerset Police warned motorists that “slow-moving roadblocks” are planned on parts of the M4, M5, M32 and A38 on Friday morning.
An image posted on Facebook group Fuel Price Stand Against Tax suggests demonstrations will be held “nationwide”, including in Birmingham, Cardiff, Liverpool, London and Manchester.
Climate protesters caused major disruption on Wednesday by climbing onto signs above the M25.
How long is the M25 and when was it built?
The M25 is also known as the London Orbital Motorway.
It is a major road encircling most of Greater London.
The M25 is 117 miles long in total and it is one of the busiest roads in the country.
It was opened in 1975 and the last section was completed in 1986, it was opened by then Prime Minister Margaret Thatcher.
At the time it was the longest ring road in Europe.
