Highways teams from West Sussex County Council continue to scope potential solutions to complex issues following the A29 Pulborough landslide, when an embankment collapsed, sending debris onto the road below.

Joy Dennis, the County Council’s Cabinet Member for Highways and Transport, said: “We totally understand the frustration of residents, business owners and other road users, facing a lengthy diversion route, and would like to assure them we are making every effort to re-open the road as soon as possible – but that can only be done once it is safe to do so.

“The issues involved are complex and the landslide occurred at the narrowest part of the A29, where both sides are flanked by steep embankments.

“Geo-technical experts have assessed the embankments and advised it is not safe to reopen the road to vehicles and pedestrians – we must adhere to this expert advice as safety has to be our number one priority.”

Both embankments have moved and worsened since the original road closure. The western side has seen more material join the pile of debris on the highway and the eastern side, which we have significant concerns with, has shown signs of slippage and material deposited on the carriageway.

Joy added: “Sadly, it is not a simple matter of clearing debris – we have been advised that disturbing material from the embankments could further undermine them and make the situation far worse.

“Trees are at risk of being brought down and there is the added complication of a sewer drain in the embankment, which has been damaged in the landslide.

“The land that has slipped is not owned by the County Council and we are continuing to work closely with the landowners involved, so officers and our specialist contractors can complete their assessments and fully design the solution that will enable the road to be reopened.”

Additional inspection assessments are being carried on other local roads, identifying safety issues for repair, acknowledging these roads are regrettably being used as informal diversion routes/cut throughs, despite the signed, official route. Several potholes have already been repaired and more repairs have been scheduled.

Other action taken by highways teams and contractors since the landslide on December 28 includes:

  • Establishing the road closure and diversion (please see map, below)
  • Improving diversion route signage, including electronic signs at key locations
  • Engineers and specialist contractors are scoping potential solutions

Further surveys are being undertaken to assess the damage to the embankments and develop options to resolve the situation.

A dedicated web page has been set up so residents, businesses and road users in general can be kept up to date with the latest information available:

Updates, including links to the latest media releases, will also be posted on the County Council’s social media channels, including via @WSHighways on Twitter, and via our residents’ e-newsletter.
