9. Handy Cross A404/M40 junction 4 roundabout closures
Highways England will be carrying out resurfacing on the Handy Cross A404/M40 junction 4 roundabout in High Wycombe over three consecutive weekends, from Friday night to Monday early morning on the weekends of Friday 16th February, 23rd February, and 2nd March. The resurfacing works require a full closure of the roundabout, as well as the approach roads leading to the junction.
While these are not TfB works, we are preparing for the disruption to traffic that the works are likely to cause in surrounding areas, and this page has been designed to help drivers, residents, and businesses prepare as well. Below you can find FAQs about the closure, maps, and contact details for Highways England.

As well as the A404/M40 junction 4 roundabout, the following approach roads will also be closed:
- Wycombe Road from Ragmans Lane
- A4010 John Hall Way from Crest Road
- Marlow Road from Cressex roundabout
- A404 Marlow Hill from Waitrose/Park and Ride
Please note the flow of the M40 itself will not be affected and motorway through traffic should move as normal; only the junction will be closed.
When exactly will the closure be in effect?
TfB has granted a Temporary Traffic regulation Order (TTRO) for the closure of the roundabout and its approach roads to be closed from 9pm Friday until 5am Monday morning on the following weekends only:
- Friday 16th February – Monday 19th February
- Friday 23rd February – Monday 26th February
- Friday 2nd March – Monday 5th
Works will take place all weekend, including overnight, in order to complete as quickly and efficiently as possible.
Why is the work being done?
Highways England is carrying out the resurfacing to ensure this essential junction remains in a safe condition. The existing road surface will be dug out and fully resurfaced, the traffic signals and detection loops will be replaced, and anti-skid material will be laid at selected areas of the roundabout.
Where is the diversion route?
During the closures various clearly signed diversions will be in place, primarily using the M40 junctions 3 and 5, the A40, Wooburn Green and Little Marlow. You can download diversion maps here.
- M40 northbound traffic for High Wycombe: exit at junction 3 or continue north to junction 5 then travel east along the A40 Wycombe Road
- M40 southbound traffic for High Wycombe: exit at junction 5 or continue to junction 2, circumnavigate the roundabout, travelling north on the M40 to exit at junction 3
- M40 northbound traffic for the A404: exit at junction 3, travel past Wooburn Green, Well End and Little Marlow, joining the A404 at Marlow
- M40 southbound traffic for the A404: continue south to junction 2, circumnavigate the roundabout, travel north to junction 3, exit at junction 3, travel south past Wooburn Green, Well End and Little Marlow, joining the A404 at Marlow
- A404 northbound traffic for High Wycombe: from Marlow travel east past Little Marlow, Well End, Wooburn Green and the A40
- A404 northbound traffic for the M40: from Marlow travel east past Little Marlow, Well End, Wooburn Green, then join the M40 southbound at junction 3. Traffic wishing to travel north will need to access the northbound carriageway at junction 2
- Wycombe Road traffic for High Wycombe or the M40: travel south to Marlow, then east past Little Marlow, Well End, Wooburn Green, joining the M40 southbound at junction 3. Traffic wishing to travel north will need to access the northbound carriageway at junction 2

- High Wycombe to the A404: travel south on the A40 towards junction 3, then travel south past Wooburn Green, Well End and Little Marlow, joining the A404 at Marlow
Significant delays are expected during these weekend closure periods, and it is advised that you plan ahead of your journey to allow for extra time or avoid this route where possible.
Will buses be affected?
The following bus routes will be diverted:
- X80 (High Wycombe - Marlow - Henley – Reading)
- 800/850 (High Wycombe - Marlow – Reading)
Details of the diversions can be found on the Service Disruption and Stop Closures page: https://www.buckscc.gov.uk/services/transport-and-roads/buses-and-trains/service-disruption-and-stop-closures/
National Express will not be serving the Handy Cross Coachway during the closure.
What is being done to lessen the impact of the closure?
Transport for Buckinghamshire has put an embargo on any other non-essential roadworks while the Handy Cross roundabout is closed, extending for 10 miles around the junction. Any emergency works will still have to go ahead. We realise that while the official diversions above will be adhered to by LGVs and non-local drivers, anyone with local knowledge or those using sat navs will likely use local roads to divert around the closure. For this reason, additional traffic management will be used in those areas in order to best manage the traffic flow. Signage will be put in place clearly advising that the smaller local roads are not suitable for LGVs.
Why is a full weekend closure necessary?
For the safety of both the workforce and drivers, a lane closure set up is not possible – a full closure is the only option for carrying out the resurfacing. There is a significant amount of work required to resurface such a large and complex junction, that if Highways England were to carry out the works under standard overnight closures with the full roundabout and all approaches shut down, it would take at least 31 nights to complete. Three weekend closures are thought to be the quickest and least impactful way to carry out the works.
Will the emergency services have access?
Emergency services will have access through the closure, as will TfB gritters should they need to get through to salt the roads, although gritting routes have been adjusted to minimise disruption.
Which businesses will be affected?
Several retailers in the area may be affected by the closure, including John Lewis and Asda in Cressex. All retailers have been contacted by Highways England to inform them of the works, and will be open as usual accessible via the diversions. There may also be a knock-on effect to the retail park in Loudwater – if you are planning a trip to any of these retailers during the closure please allow extra time for your journey.
What other works will be done under the closure?
TfB will be collaborating with Highways England to make use of the road closures on the approach roads, and carry out maintenance works such as small scale resurfacing, gully clearing, sign cleaning, and street lighting repairs.
Who do I contact to discuss this closure?
