    This is a final reminder that there is a full closure of the M4 this weekend in both directions between junctions 5 (Langley) and 6 (Slough/Windsor).

The motorway will reopen on Monday 30th September by 6am.
  • The demolition work will begin overnight on the Friday and continue all weekend at all hours until it is complete. Motorway traffic will be diverted to the A4 and A355 through Slough for the duration of the closure. Recreation Ground bridge will be replaced in late Summer 2020 and re-open as soon as possible after then.
  • There is also a wider regional diversion plan that will advise drivers on the M25 heading west to use the M3 or M40 and then re-join the M4 further along - the westbound slip roads linking from the M25 junction 15 to the M4 junctions 4b will be closed over the weekend to help manage traffic.
  • Similarly, drivers heading east on the M4 towards London will be advised to leave the M4 and redirect to the M3 and M40 to join the M25, or to reach destinations in Berkshire. Clear signs and signals will be in place on the network over the weekend.
  • There are two further closures between junctions 6 and 8/9 of the M4 in mid and late November to allow for the demolition and construction of bridges - with more to come in 2020 and 2021.
  • Regular updates will be posted on this page over the weekend.

    Our response to your recent comments

    This is the latest response to your comments on the Commonplace site. Please remember, if you have a specific question or concern and would like an individual reply, please email us at:

    Heavy vehicles using Marsh Lane

    We’re sorry to hear about the concerns raised by residents of Marsh Lane. We have contacted the supplier/subcontractor and have requested their drivers are reminded of the courtesy we expect to be given to our neighbours, and the importance of their speeds en route to site. It will be re-iterated that they should travel at a more sedate pace. We have been advised that our vehicles do not park up along Marsh Lane near the A4, however again we have spoken to the supplier and requested this remains the case to ensure we are not blocking any traffic in this area.

    Air quality, dust, noise, ecology and wildlife

    Dust: we have a duty of care to mitigate dust. We do this by ensuring the materials we are using in the embankments have a moisture content of around 9% for compaction and as the materials dry we always try to dampen down as best we can in both warm and colder weather.

    Ecology, wildlife and vegetation clearance: all vegetation removed is in accordance with the works detailed in the Development Consent Order for the M4 smart motorway. Before the project commenced an environmental assessment was carried out which included ecology surveys for protected and invasive species. Pre-site checks are carried out by the ecology team directly before vegetation clearance is started.

    Noise: as with any activity (day or night) we try our upmost to reduce disruption as far as is practicable. We will, where possible, ensure mitigation measures are in place so disturbance to our neighbours is kept to a minimum. Please be aware, in the area of Winnersh, Sindlesham, Wokingham and Lower Early, for example, there are a number of projects taking place. Some of these fall under the responsibility of Wokingham Borough Council and more information about their projects can be found at: http://www.wokingham.gov.uk/roadworks-and-outdoor-maintenance/major-new-roads/north-wokingham-distributor-road/

    Air quality: this is a complex issue that was subject to extensive examination during the DCO process. You can find the details of this issue here at the Planning Inspectorate site , but please get in touch if you have a specific question about your area.

    The countdown markers leading to Junction 10 have disappeared

    There are three advance signs in position for the exit at junction 10 eastbound, they are black on yellow signs which is the standard for temporary signage within roadwork areas. In addition there are white on blue countdown markers between these signs, these are in place on the verge.

    Not enough notice on the motorway signs for closures/diversions

    When we have an overnight closure we are required to place advanced signs at slip roads and in the verge in the direction of the closure i.e. between junctions 8/9 and 10. We are also required to include advance diversion signage; the diversion signs would then direct traffic on to the approved primary diversion route.

    A great deal of planning goes into our roadworks and closures, and to help you plan your journeys and to keep up to date with road closures in the future, we've included some links below:

  • https://www.roadworks.org/
  • http://www.trafficengland.com/traffic-report
  • You can also sign up to news alerts from this site, and every Friday you will receive a list of planned closures for the following week.

    Length of roadworks

    Some have asked again why the roadworks are designed in the current format. Safety is the highest priority when planning works. Stopping sight distances, thinking time, reaction time and impact forces all change significantly between 70mph and 50mph. The locations and extent of all speed restrictions are carefully considered during the design and planning of the scheme and implemented for a specific reason.

    The length of the roadworks is important for delivering the scheme efficiently and reopening the motorway as soon as possible. Putting in and removing roadworks takes significant time and requires closures of the motorway so moving the layout on a regular basis would be very disruptive. We have passed on comments about the temporary white lines to the traffic management team.

    The signage is designed and set out in line with national guidelines, but also to ensure that the road is not ‘cluttered’ with signs that might confuse drivers or obscure other signs. We are responding to concerns about signage and review the approach regularly.

    Also, a reminder about what to do if you break down in the roadworks. We offer free recovery to a place of safety during roadworks and a handy guide to what to do can be found here, or in your highway code:

    https://www.gov.uk/government/organisations/highways-england/about-our-services#free-recovery .

    M4 interface with the M25

    Several of you have asked again about the plans for junction 4b. The eastbound approach to the M25 currently consists of 4 lanes, just one of which leads to the exit to the M25 and is prone to congestion. The completed smart motorway will become a 5-lane road on the eastbound approach to the M25 at junction 4b. Lane 1 will lead to the M25 northbound, lane 2 will lead to the M25 southbound, while lanes 3, 4 and 5 will continue towards London. See the image below for the new layout.

    Use of the A4 as a diversion route

    Some of the activities for the smart motorway upgrade require us to close the M4 between junction 11 and junction 12. Due to traffic volumes we are not able to close carriageways during the day so certain activities have to take place at night. When we do close the M4 at night between junctions 11 and junction 12 we use the strategic diversion route via the A4 and A33 which has been in place since the M4 was built and has been authorised for use by the Local Authority. Only vehicles legally allowed to use those A roads (usually vehicles up to and including 44 tonnes) are diverted onto the network. Generally any vehicles over this size would be classified as an abnormal load and are required to give notice of their movements to the relevant authorities. These would then be restricted from moving on the nights the motorway was planned to be closed.

    In order to close the carriageway there are a number specific restrictions we have to comply with. One of these restrictions relates to traffic volumes, only when the traffic flow for the carriageway to be closed drops below a count which is suitable for the capacity to run in single lane will the motorway be closed, this is usually between the hours of 21:30 and 06:00. We would also only ever close one carriageway at a time unless there were special requirements like a bridge demolition which affected both carriageways simultaneously. This to date has not taken place although it will be required at some point. For reference, we are working round the clock whilst keeping three lanes of traffic open in each direction during day time running. We are doing our upmost to keep our closures to a minimum which will lessen the impact on the A4.

    Our response to your recent comments

    This is the second of our responses to your comments on the Commonplace site. Also, our latest monthly news bulletin for May is out and can be found here.

    The issues you have raised recently fall into four main themes:

    Timetable of the project

    We are constantly reviewing the programme to ensure that our delivery of the project is as efficient and effective as possible, and remains on time and on budget. This may mean that certain works will be brought forward and traffic management is extended ahead of schedule. The aim is to reopen sections of the completed smart motorway as soon as possible. Keep an eye on our websites for updates on the overall programme in due course.

    We have begun enabling works at various sections of the motorway route including at the structures and we always endeavour to minimise disruption as much as possible. The key thing is that the roadworks will be set out with three narrow lanes always open at peak times (this means daytime, except for some weekend closures during the project), a 50mph speed limit, and free recovery if you break down in the construction area.

    Purpose, aims and safety of smart motorways

    The starting point for smart motorways is that many of England’s most important roads are heavily congested and this includes the M4 Junctions 3 to 12, which links London to Windsor, Slough, Maidenhead and Reading – the Thames Valley economic area which hosts major tourist attractions such as Legoland and Windsor Castle. By reducing congestion and increasing capacity smart motorways support economic growth.

    The conversion of the hard shoulder is crucial to providing extra capacity on the road along with the supporting technology such as signs and signals, CCTV, emergency areas for breakdowns and Red X signs to close lanes in the event of an incident.

    Smart motorways are developed almost wholly within the existing highway boundary and therefore have a lower environmental impact than traditional widening schemes.

    Our research shows that the latest generation of smart motorways are performing well in line with expectations. Data released last year for the M25 J5-7 and J23-27 All Lane Running (ALR) schemes show that capacity has been successfully increased and they are meeting or exceeding their safety objectives. Across the two schemes the casualty rate reduced by 27%. The overwhelming majority of drivers are complying with the Red X. These smart motorways have also successfully reduced the stop-start congestion that smart motorways were designed to tackle. We are confident that this will be replicated on the M4 J3-12.

    Roadworks issues

    Some have asked again why the roadworks are designed in the current format. Safety is the highest priority when planning works. Stopping sight distances, thinking time, reaction time and impact forces all change significantly between 70mph and 50mph. The locations and extent of all speed restrictions are carefully considered during the design and planning of the scheme and implemented for a specific reason.

    The length of the roadworks is important for delivering the scheme efficiently and reopening the motorway as soon as possible. Putting in and removing roadworks takes significant time and requires closures of the motorway so moving the layout on a regular basis would be very disruptive. We have passed on comments about the temporary white lines to the traffic management team who will investigate this issue.

    The signage is designed and set out in line with national guidelines, but also to ensure that the road is not ‘cluttered’ with signs that might confuse drivers or obscure other signs. We are responding to concerns about signage and review the approach regularly.

    Also, a reminder about what to do if you break down in the roadworks. We offer free recovery to a place of safety during roadworks and a handy guide to what to do can be found here, or in your highway code:

    https://www.gov.uk/government/organisations/highways-england/about-our-services#free-recovery .

    M4 interface with the M25

    Several of you have asked about the plans for junction 4b. The eastbound approach to the M25 currently consists of 4 lanes, just one of which leads to the exit to the M25 and is prone to congestion. The completed smart motorway will become a 5-lane road on the eastbound approach to the M25 at junction 4b. Lane 1 will lead to the M25 northbound, lane 2 will lead to the M25 southbound, while lanes 3, 4 and 5 will continue towards London. See the image below for the new layout, which you can also see in the video below.

    Our response to your recent comments

    There has been quite a bit of activity on the Commonplace site and we have responded to some of the comments residents and road users have raised with us in the article below. Also, our latest monthly news bulletin is out and can be found here.

    The issues you have raised fall into five main themes:

    Roadworks

    The design and extent of the traffic management layout has had mixed views with some suggesting that the new layout and restricted speed has improved journeys along the M4 by smoothing the flow of traffic at peak times.

    Some have asked why the roadworks are designed in the current format. Safety is the highest priority when planning works. Stopping sight distances, thinking time, reaction time and impact forces all change significantly between 70mph and 50mph. The locations and extent of all speed restrictions are carefully considered during the design and planning of the scheme and implemented for a specific reason.

    Some have asked about what to do if you break down in the roadworks. We offer free recovery to a place of safety during roadworks and a handy guide to what to do can be found here, or in your highway code: https://www.gov.uk/government/organisations/highways-england/about-our-services#free-recovery .

    For questions about the A329M, any work taking place is generally the responsibility of the Highways England Area 3 operations and maintenance team (contact info@highwaysengland.co.uk for more information) or Wokingham Borough Council. There are however 50 mph speed restrictions in place on the A329M as you approach the M4 to ensure people merge into the roadworks on the M4 at a sensible speed.

    Some of you mentioned that signs were out of place or missing in early March – this was due to a few days of high winds that unfortunately took us a little while to resolve and get everything back in order.

    Timetable of the project

    The overall end date for the whole scheme is Spring 2022, however there are changes currently taking place to the programme and we will be updating the websites in due course. There is a variety of work taking place up and down the route and we are continuously reviewing our work programme to ensure we can deliver the project as efficiently and effectively as possible. This includes extending traffic management to different sections of the route between to allow for enabling work and the installation of technology at different locations to better prepare for the start of main work. The programme is of course subject to change throughout the scheme.

    Noise from works at night

    Night work is unavoidable due to the requirement to keep 3 narrow lanes open through our roadworks during the day. When we have overnight works, we do try our upmost to reduce noise as far as is practicable and ensure disturbances to our neighbours is kept to a minimum. We will continue to do this for our planned overnight activities and ensure, where possible, mitigation measures are in place. Our community relations team also writes out to local residents near the motorway when noisy works are coming up. If you live in a brand new estate near the M4 this might not have been considered as part of the M4 Development Consent Order granted in 2016. We recommend asking the housebuilder and the local authority what noise mitigation measures are included in the planning conditions attached to the permission for the development.

    Safety of smart motorways

    Our research shows that the latest generation of smart motorways are performing well in line with expectations. Data released last year for the M25 J5-7 and J23-27 All Lane Running (ALR) schemes show that capacity has been successfully increased and they are meeting or exceeding their safety objectives. Across the two schemes the casualty rate reduced by 27%. The overwhelming majority of drivers are complying with the Red X signals which are used to shut off lanes in the event of an incident. These smart motorways have also successfully reduced the stop-start congestion that smart motorways were designed to tackle. We are confident that this will be replicated on the M4 J3-12.

    Activity at our compounds

    We have made changes to certain work based on your feedback. Our local compounds have been reduced in size and number thanks to the large compound and office site near J10 but we still have a local presence and aim to good neighbours. We have responded to concerns about noise and light pollution at our local compounds and have made changes where possible. If have any questions or issues about our works near you home, please do get in touch.
