Farthing Drove, Sedge Fen closure

Details of the emergency closure along Farthing Drove, Sedge Fen, Lakenheath and diversion route.

Update - 7 July 2020 

We can now confirm that UKPN have gained consent to divert the overhead power cables which are in close proximity of the culvert collapse into a nearby field, this will then enable our contractors to safely repair the damaged culvert.

UKPN has programmed in to erect the temporary power poles from Thursday 27 August, with the aim of having this completed by Friday 4 September. Our contractors will then be able to start works to repair the collapse from Monday 7 September. We estimate that the works to rebuild the culvert and the bank, including resurfacing of the above section of road will take approximately six weeks.

UKPN will then return to reinstate the main power lines with the aim of reopening the road by the end of October 2020.

We apologise for any inconvenience this has caused and appreciate that the closure may be causing some disruption, however, please be assured that our teams are working to get the road reopened as soon as possible. We will continue to provide updates as soon as they are available.

Surface dressing - 2 and 3 May 2020 

We will be surface dressing sections between the east side of the culvert through to B112 High Street. Please note that our aim is to complete this work over two days however, it may be necessary for the works to continue on Monday 4 May.

Once the culvert has been repaired, our teams will return to complete the remaining surfacing works.      The road will be temporarily closed for the duration of the works, access will be managed by staff on site. Please be advised that there may be a short delay until the site is made suitable for safe passage. 

Update - 21 April 2020 

Due to Covid-Farthing drove concrete bollard19 UK Power Networks has suspended all planned maintenance works and is currently only dealing with essential and urgent works. However, we have continued to work alongside their engineers to progress preparations for the temporary installation of a high voltage line diversion at Sedge Fen.

Once the plans for the diversion have been finalised, a date to install the diversion will be scheduled. This will enable our teams to safely repair the damaged culvert. Once again, we thank you for your patience.

Update - 13 March 2020

Our teams have been onsite today with our contractors and UK Power Networks to determine what works are required prior to the repairs taking place on the damaged culvert.

In order for our teams to carry out works safely, UKPN will be arranging to either isolate or the remove the overhead cables which are in close proximity to the collapse.

We appreciate that the closure may be causing some disruption however, please be assured that our teams are working to get the road reopened as soon as possible. We will continue to provide updates as soon as they become available.


Reason for closure

An emergency closure has been installed along Farthing Drove, Sedge Fen. This is due to a damaged culvert which has resulted in a collapse under the road.

Due to the thickness of the tarmac the road is currently holding up and bridging over the hole however, there is a 3m wide void extending at least half the way under the road.

It is vital that the closure is in place until further investigations and repairs are carried out as the extent of the damage means it could give way at any time under the weight of a vehicle.

Required works 

We are working on designs for the reconstruction of the embankment and culvert and are liaising with specialist contractors to make sure the repairs are completed as quickly as possible.

Due to an overhead high voltage electricity supply which is in close proximity of the collapse, we will be working with UKPN to ensure we can all work safely whilst maintaining power for the local community.

Public barriers installed

Due to members of the public moving  closure barriers have been installed. Concrete barriers will be installed either side of the collapse to prevent through traffic and the risk of further collapse and potential road traffic accidents.
