M25 Roadworks

Welcome to the roadworks section of M25 Traffic.

In the roadworks section we feature news and updates about current and planned roadworks on the M25 motorway.

You can also visit our "accidents and incidents" section for information about accidents and incidents on the M25 causing delays today.

So, if you are looking for information about roadworks you have come to the right place.

Roadworks are one of the main causes of congestion, delays and holdups. In recent years there have been extensive road widening programs on the busiest sections of the motorway which has lead to long delays.

As the M25 motorway is one of the busiest roads in Europe, roadworks can cause long delays to drivers especially at peak periods, and on the busiest sections of the motorway.

Our main source of news and updates about roadworks is from Traffic England which is the government department responsible for maintaining the roads and motorways in England, so our main source is an official, reliable one.

Roadworks Info

The main source of our roadworks information is Traffic England, formally the Highways Agency, which is the government department specifically tasked with maintaining England's roads. This is therefore usually one of the most reliable sources of roadworks updates.

Each roadworks report has:

Report title
Date Released or updated
Category or Source
Location
Schedule
Summary

The roadworks update title is a brief summary of main facts.

The remainder of the report is the detail of when the report was released or updated and details of what the roadworks are, where they are, and how long they are expected to last.

How any accidents on the M25 are affecting speed of traffic flow

M25 Traffic now features real time traffic flow information from Google maps which will show how current accidents are slowing traffic speed.

Using the traffic flow map in conjunction with our traffic news helps to gauge the affect any accidents on the M25 are slowing down traffic.

We see reports of accidents on the M25 most days. Our aim is to feature all the current accident reports from Traffic England as soon as they are reported.

You should never drive and text at the same time. This creates a massive risk of a traffic accident to you and others around you.

Be alert, be aware, take care. Be safe.

You should never drive and use your phone at the same time. Have a passenger check our latest news for you.

On any single day you can find information about both current and planned roadworks so that you are aware of possible delays and holdups on your journey.

As a major motorway, and a very busy one, we often feature dozens of up to date reports and updates and you can find all of them in our central search news page.

This page highlights up to ten of the most recent and latest reports.

Our search page enables you to search by category and narrow your search down to specific junctions and specific words such as "clockwise" or "anti-clockwise" which can be very useful.
