In 2024, the M25 will be closed between junctions 9 and 10 from Friday, May 10, at 9 p.m., until Monday, May 13, at 6 a.m.
According to National Highways, the cost of the junction enhancement work was £317 million.
Prior to this, in March, the government agency decided to close the motorway as part of the rehabilitation plan. A bridge was destroyed and a new gantry was built while the busy road was closed.
While the roads are closed, another section of the M25 will need to be closed as workers move concrete beams into position for the eastern gyratory bridge and another enormous gantry.
“This is far from a repeat of the previous closure,” stated Jonathan Wade, senior project manager for National Highways, “because the alternative routes are different and longer for over-height vehicles and all other traffic.”
“The last time, drivers followed our instructions, which resulted in a reduction of motorway traffic by more than two thirds and little delays.
“Once again, please only travel if absolutely necessary. If you do choose to use the M25, make sure you allow extra time for your trip.”
Drivers can use National Highways’ pre-mapped diversion routes to avoid this section of the M25. It is advised, however, that drivers plan ahead for their travels.
The traffic agency is seeking to establish a third closure date for the plan, which is scheduled to be finished in the summer of 2025.
