A MAJOR motorway is set for its third closure this year alone when a section is cordoned off next month to install a "new bridge deck".
The route is currently at the centre of a £317 million infrastructure project, with more shutdowns expected in the coming months.
The M25 experienced a first-ever daytime closure in March to allow workers in Surrey to carry out planned repairs.
The area is undergoing a major refurbishment, with a significant junction being overhauled.
In the first of five stages, drivers were barred from the route in both directions between Junctions 10 and 11.
This was followed by another closure in May.

Now, though National Highways has announced the beginning of the third section of the plan.
It will be Junctions 9 and 10 affected this time, with varying levels of restrictions.
The westbound carriageway will be fully shut between the two junctions, while the eastbound carriageway will only close down at junction 10.
Nonetheless, the works will still encompass Cobham Services, making it inaccessible for motorists.
Officials confirmed that work will be completed between 9pm on June 8 and 9am the next day.
A number of diversions are in place to get around the westbound closures.
Meanwhile, drivers looking to go East will have to come off at the Junction 10 slip road and negotiate a roundabout before rejoining via an entry slip road at Junction 11.
A spokesperson for National Highways said: "Between 9pm on Saturday, June 8 and 9am Sunday, June 9, we're closing the westbound carriageway of the M25 between Junction 9 and 10 and this will also include Cobham Services.
"This is to install a new bridge deck over the eastbound gyratory.
“The eastbound carriageway which will also be closed on the M25 at J10 during this time with a diversion via the exit slip, roundabout, and entry slip road where road users will be able to re-join the M25.
"Please do not to use a sat nav when following any of our diversions because there is a risk it could direct you down an unsuitable road or back onto the network where it is closed."
The date for the final two closures have not yet been revealed but is expected before September.
