Motorists in Surrey are warned to prepare for significant disruption as the M25 motorway undergoes a major closure from 9pm on May 10 until 6am on May 13. The closure affects the busy stretch between junctions nine and ten, leading to expected long delays and heavy traffic congestion.
This shutdown is the second of five planned weekend closures linked to a £317 million upgrade project at junction 10. During this period, large concrete beams, some weighing up to 40 tonnes, will be installed to construct a new bridge and gantry, rendering the road impassable.
Drivers will be diverted along a 19-mile alternative route via the A3 and A243. Following the official diversion route ensures that no Ultra Low Emission Zone (ULEZ) charges will apply. However, ULEZ restrictions remain active on all other London routes, so motorists should remain vigilant.
Jonathan Wade, senior project manager at National Highways, emphasised the importance of adhering to diversion signs, particularly for over-height vehicles which face longer detours. He stated, “Please heed all advice to reduce congestion and keep delays to a minimum.”
The installation requires 68 beams weighing 16 tonnes each, plus four massive 40-tonne beams. This work is expected to cause serious traffic issues at one of the UK’s busiest motorway junctions, which handles up to 270,000 vehicles daily.
The overall project aims to improve traffic flow and safety, with completion targeted for summer 2025. Meanwhile, drivers and businesses should prepare for considerable logistical challenges during the closures.
National Highways is coordinating closely with emergency services, local councils, and airports to minimise disruption for residents and travellers. Authorities encourage motorists to plan their journeys in advance, consider alternative routes, and avoid the closed section of the motorway where possible.
There is some relief for drivers in June, as no weekend closures are scheduled before further shutdowns planned between July and December. Dates for these will be announced following the May closure.
The key message from officials is to follow diversion routes, remain patient, and support the smooth progress of these essential upgrades.
