Busiest Sections of The M4

The M4 motorway is one of the busiest and most important roads in the UK, connecting London and South West England, as well as providing access to Wales and Heathrow Airport. However, not all sections of the M4 are equally busy. Some sections experience more traffic than others, especially during peak hours and holidays.

Knowing which sections of the M4 are the busiest can help you avoid delays and plan your journey better. According to official data from 2018, the busiest section of the M4 is junction 4B/M25 to junction 4 near Heathrow Airport, with 159,500 vehicles using it every day. This section is also part of a smart motorway, where there are variable speed limits and a part-time hard-shoulder.

The next busiest section is junction 15 to junction 16 for the M40 motorway, with 201,000 vehicles per day. This section is also near Heathrow Airport and London. The third busiest section is junction 13 at Staines to junction 14 near Heathrow Airport, with 206,000 vehicles per day. This section is also part of the M25 orbital motorway, which is the most congested road in Britain.

If you want to avoid these busy sections of the M4 motorway, you can use our live M4 travel news and information service, which provides you with real-time updates on traffic conditions, roadworks, accidents and congestion. Our service will help you find the best route and time to travel on the M4 motorway.

Alternative Routes

The M4 motorway is a convenient and direct route for many drivers, but sometimes it can be congested, closed or affected by roadworks. In such cases, it is useful to know some alternative routes to the M4 that can help you reach your destination without too much hassle. Depending on where you are travelling from and to, there are different options for avoiding the M4. Some of them are:

  • Using other motorways, such as the M25, M40, M3 or M5, which can connect you to different parts of the country and bypass some of the busiest sections of the M4. For example, if you are travelling from London to Bristol, you can use the M40 and M5 instead of the M4.
  • Using less-used roads, such as the A-roads or B-roads, which can offer more scenic and quieter routes than the motorway. However, these roads may be slower, narrower and more prone to traffic lights and roundabouts. For example, if you are travelling from Reading to Swindon, you can use the A4 instead of the M4.

Scenic Places To Visit

The M4 motorway is a convenient and direct route for many drivers, but sometimes you may want to enjoy some scenic views along the way. There are many beautiful places near the M4 that can offer you a break from the motorway and a chance to admire some of the best landscapes in England and Wales. Some of them are:

  • The Cotswolds, which are a range of hills and valleys that span several counties in south-west England. The Cotswolds are known for their picturesque villages, historic buildings, rolling countryside and wildlife. You can access the Cotswolds from various junctions of the M4, such as junction 15 for Swindon, junction 18 for Bath or junction 13 for Newbury.
  • The Chiltern Hills, which are a chalk escarpment that stretches from Oxfordshire to Bedfordshire. The Chiltern Hills are designated as an Area of Outstanding Natural Beauty and offer scenic drives through woodlands, fields and villages. You can access the Chiltern Hills from junction 8/9 of the M4 for Maidenhead or junction 6 for Slough.
  • The Seven Sisters Cliffs, which are a series of chalk cliffs that form part of the South Downs National Park in East Sussex. The Seven Sisters Cliffs offer stunning views of the English Channel and the surrounding countryside. You can access the Seven Sisters Cliffs from junction 10 of the M4 for Wokingham or junction 11 for Reading.
  • The Brecon Beacons, which are a mountain range in south Wales that form part of the Brecon Beacons National Park. The Brecon Beacons offer scenic drives through rugged terrain, waterfalls, lakes and forests. You can access the Brecon Beacons from junction 32 of the M4 for Cardiff or junction 24 for Newport.

  1. On Saturday 19 March at approx midnight, I will drive from London to Windsor on the M4 hoping to exit at junction 6 for Windsor. Will I be able to do this smoothly or will there be deviations on my way to Windsor from London for M4 works on Saturday the 19th of March? Thanks

  2. Hi

    Please can you confirm is there a diversion set up just before junction 8/9 of the M4 as I need to get on the M4 to travel to Somerset.

  3. please can you put closures on M4 as I have to give news to my hubby who, at present, is driving a coach between Cardiff to Heathrow, or London Victoria or Bristol Airport. Your website is atrocious at trying to find out what is closed, when its closed and its opening hours. We need it in plain speak please to make professional drivers less tense and able to work out if they have to divert.
