A40 Leys Bend Rockfall

Latest updates

• 19 December 2024

  Installation of the contraflow

  We’ll be installing our contraflow traffic management layout on the A40 at Leys Bend on 6 January 2025. The contraflow will ensure we can continue to keep the A40 open in both directions when undertaking the removal of vegetation and debris from the carriageway. It also allows our teams to survey the hillside safely.

  To install the contraflow safely, the A40 eastbound between Dixton roundabout and Whitchurch will be closed overnight on 6 January between 8pm to 6am.

  Diversions

  There will be clearly signed diversion routes for both HGV and long-distance traffic.

  We’ll provide another update in January with the proposed new date for the overnight installation of the contraflow.

  Cancellation of contraflow for the Christmas period

  The installation of the contraflow that was programmed to take place on the evening of 16 December 2024 has now been cancelled.

  We’ve amended our programme of work to ensure smoother and safer journeys for road users travelling on the A40 during the Christmas period.

  A contraflow is the best option for us to use when undertaking the removal of vegetation and debris from the carriageway. It also allows our teams to survey the hillside safely.

  We’ll still close the A40 as outlined below so we can prepare the A40 for the installation of contraflow at the start of the new year but by reorganising our programme to undertake our main works in early January, we’re able to leave our traffic management in its current arrangement of single, narrow lanes until that time without affecting our timescales.

  The closures to prepare the contraflow will take place on the follow dates:

  • 11 to 13 December, from 8pm to 6am each night.
  • A40 eastbound closed between Dixton roundabout and Whitchurch.

  Diversions

  There will be clearly signed diversion routes for both HGV and long-distance traffic.

  Preparation work

  Our preparation work to install traffic management will begin on 29 October. 

  This work will focus on installing safety barriers, temporary CCTV cameras and crossover locations, and will allow us to put in place a contraflow system in November.

  So our teams can safely carry out this work, the following overnight closures will be in place between 9pm and 6am:

  • 29 October: A40 eastbound closed between Dixton roundabout and Whitchurch
  • 30 & 31 October and 1 & 4 November: A40 westbound closed between Whitchurch and Dixton roundabout

  This means that the westbound carriageway will be reduced to one lane from 6am on the morning of 31 October 2024. A free recovery service will be in place during this time. 

  Clearly signed diversion routes will be in place for both HGV and long-distance traffic.

  Update: traffic management for debris removal

  We’re progressing our plans for the removal of the rockfall debris from the A40 at Leys Bend, while also designing a scheme for the long-term solution which is currently planned to start in early 2025.  

  What’s happening?

  Since the rockfall took place, we’ve installed a concrete barrier between lanes 1 and 2 on the eastbound carriageway to prevent any of the fallen material rolling or washing onto the live lane. It’ll also ensure the area is kept safe and traffic can keep moving. We’ve also gained legal access to the privately owned hillside. Surveys will continue to take place to monitor the stability of the hillside.

  

  When we clear the rock and loose debris from the area, we’ll be removing vegetation in the area immediately around it.  Ecological and environmental surveys will be carried out before and during the work in consultation with Natural England. We’ll also ensure vegetation clearance is limited to only what is necessary, minimising the impact to the environment and wildlife.

  Once vegetation, soil and rock have been removed from the location of the fall, we’ll be carrying out detailed examinations of the slope to allow us to determine the most appropriate method to manage the long-term risk in this area.  This may include netting, rock bolts or a safety fence. 

  When will this work take place?

  A programme of work has been produced in consultation with Herefordshire Council, Monmouthshire County Council and South Wales Trunk Road Agent, to safely remove the rockfall from the carriageway.

  The rockfall will be removed in October and November 2024 which minimises the scheme’s impact on local residents and the travelling public. by avoiding other schemes affecting the road network in Monmouth as well as the peak tourist season. The design of the remedial works will then be carried out and its construction will start in early 2025. 

  What’s a contraflow?

  We’ll use a contraflow system to keep the A40 open in both directions while the rockfall is removed, the area is made safe, and surveys are carried out on the hillside.

  

  A contraflow is when the road is shut in one direction and traffic is then moved over to drive on the other side of the road to share the remaining carriageway. This provides us with a clear working area that enables us to work more safely and efficiently.  For this scheme, the westbound carriageway will be kept open to enable us to keep one lane of traffic in each direction running while we carry out our work.

  We might need to temporarily close the carriageways overnight. In these instances, a clearly signed diversion route will be put in place for both local and HGV traffic.

  Diversion Route

  No daytime closures are currently planned and so diversion routes will be used overnight.

  

  All HGV and long-distance traffic will be diverted via the M5 and M4.  Local traffic will be diverted from Abergavenny on the A465 to Hereford and then the A49 to Ross on Wye

  Eastbound carriageway - update

  On Monday 19 February, we successfully opened lane two on the A40 eastbound carriageway with a reduced speed limit of 40mph. Lane one currently remains closed, and we’ve installed a temporary concrete barrier to separate the area from traffic and stop any material from falling into lane two.

  We’re regularly monitoring network performance and traffic in the area to understand if there are any additional measures we can put in place to improve journeys for road users.

  Our team is currently working on plans for repairing the hillside and rockface above the A40. Due to the complex nature of this incident, and loose material on the hillside, it’s likely this work will take several months to plan and complete.

  Repair work will be designed and led by engineering specialists, to ensure the long-term stability of the hillside. In the meantime, we aim to keep lane two open to traffic.

  As our survey work progresses, additional risks may be identified meaning we’ll need to install road closures to put in place safety precautions. Should this be necessary, we’ll issue regular updates and make sure disruption to the local community and travelling public are kept to a minimum.
