Major M25 Shutdown: Brace for Impact as Key Segment Closes for £317 Million Revamp

Unprecedented Weekend Closure Ahead:  9pm on Friday March 15 until 6am on Monday March 18

In an unprecedented move, the M25, known as the UK’s arterial roadway, is slated for its first daytime closure in a significant section, heralding potential travel disruptions across Surrey. The comprehensive closure, affecting both carriageways between junctions 10 and 11, comes as part of a hefty £317 million upgrade initiative spearheaded by National Highways.

Essential Travel Only Advised

Scheduled from the evening of Friday, March 15, to early Monday, March 18, National Highways has issued a stern advisory for motorists to limit their use of this crucial stretch to essential journeys only. The anticipated closure is not just a concern for those directly on the M25 but is expected to send ripples through adjacent routes, affecting travellers heading to major airports like Gatwick and Heathrow, as well as those bound for the Channel ports or the capital for leisure and events.

This pivotal shutdown marks the beginning of a series of closures, with four more expected by September, all aimed at facilitating major works including the demolition of a bridge and the installation of a new gantry between Wisley and Chertsey. The implications for traffic are significant, with potential congestion spillovers onto other parts of the M25 and nearby motorways. On a typical weekend, the affected sections see a traffic flow of 4,000 to 6,000 vehicles per hour in each direction, underscoring the scale of expected disruption.

Preparing for Travel Disruptions

With more than 200,000 vehicles predicted to feel the impact of the closure, National Highways, emphasises the extensive planning that has gone into mitigating the effects of this necessary but disruptive upgrade. Alternate routes and diversion strategies have been meticulously arranged, yet travellers are advised to anticipate significant delays and, where possible, to seek alternative modes of transportation.

Navigating Around the Closure

For those needing to circumvent the M25 closure, the North Orbital Road presents a viable detour, especially for navigating North and West London. This alternative mirrors much of the M25’s originally planned route, offering a less congested pathway during this critical period.

Exploring Alternatives

During this time of expected roadway congestion, travellers are encouraged to consider alternative forms of transport. Public transportation, including trains and buses, offers a sustainable option, potentially alleviating the pressure on diversion routes and contributing to a smoother journey for all. For local journeys, cycling or walking could provide not only a healthy alternative but also a way to enjoy the early spring weather, avoiding the stress of traffic altogether.
