M25 Road Closures

The M25 motorway is one of the most important parts of the UK's road network.

Acting as a ring around the Greater London area, the M25 covers around 117 miles (188 km). Which makes it one of the busiest orbital roads in the whole of Europe.

Given the amount of traffic which uses the M25 on a daily basis and the frequent congestion, staying informed about current conditions can significantly improve your journey.

M25 Planned Closures

We track the planned road closures of the M25, helping motorists to stay informed of any potential closures - including M25 road closure today.

Such is the size of the motorway, it is inevitable that there is often road works required to keep it running smoothly - with even M25 overnight closures.

As such, whole sections of the M25 can be closed or reduced in capacity whilst work is carried out.

Here we have a table of the planned road closures for the next 7 days on the M25 — from 18/06/2025 to 24/06/2025.

History of the M25

The development of the M25 dates back to the 1970s and 1980s, although its conceptual origins stretch back further.

Construction began in the mid-1970s, and the motorway was completed in stages over the following decade.

The final segment was officially opened by Prime Minister Margaret Thatcher in October 1986.

Rather than being built as a single project, the M25 was created by joining a series of smaller bypasses and ring roads.

Over the years, major enhancements have included the expansion of key junctions and the introduction of smart motorway systems designed to manage traffic flow more efficiently.

Notable M25 Features

Dartford Crossing - While not technically part of the M25 (it's the A282), the Dartford Crossing completes the loop across the River Thames. It includes both a tunnel and a bridge, and tolls apply for north-south travel.

Smart Motorway Sections - Several stretches of the M25 use variable speed limits and hard shoulder running to ease congestion.

Service Areas and Junctions - With numerous junctions connecting to other major routes, and multiple service areas like Cobham and South Mimms, the M25 is essential for both local and long-distance travel.

M25 Travel Tips

The M25 is one of the UK’s business roads.

So it is always a good idea try and reduce the chances of getting caught in heavy traffic as much as you can.
Here are some tips to try and reduce the amount of time you are stuck in traffic on the M25:

1. Before you begin your journey quickly check the latest traffic reports. This is how you can identify any potential incidents or delays on your route. If there is a major delay record, then it will give you time to assess other travel or route options. Or at the least prepare you mentally for delays if you can’t avoid that section of road. 
2. There are a number of great traffic apps that can help you stay up to date with the latest information. Or, make sure that you are listening to the local radio stations for real-time traffic information. Staying aware of any updates after you have set off again allows you to make decisions to change routes if needed when on the road.
3. Be prepared for different weather types. The weather can significantly impact your driving experience. Make sure your vehicle is equipped for any poor weather. Remember to adjust your driving to the conditions of the road.
