A183 Coast Road realignment

Background of the project

Careful consideration has been taken in the development of this project. 

In May 2019 we asked for specialist advice from Royal Haskoning DHV, a company with an international reputation in this field.

They were commissioned to monitor surveys and provide a greater understanding of the behaviour of the cliff edge at critical 'pinch point' sections of Marsden Bay. 

Their report explained that due to ongoing erosion of the cliff face and the creation of cave formations, the A183 Coast Road would in future be compromised. It also provided advice on safety thresholds and actions to be undertaken.

One action was to commence work on realigning the road, which is what we did.

Why did we not stop the cliff erosion

The advice within the report concluded that it is not a practical option to locally defend the cliff line around the 'pinch point' sections due to the negative effects it would have on the rest of the bay.

Instead, the whole bay would have to be protected which would not only have unaffordable economic impacts, but would also result in the potential loss of key geological features in an area that is a Site of Special Scientific Interest. 

Any coastal defence against marine erosion would not stop the change in the cliff line.

Planning application

We appointed design consultant Capita to produce an initial scheme design. Following this, further investigations were carried out and a final design was produced by Capita.

A planning application was submitted and consent was granted in February 2022.


The Lime Kilns

To ensure there was no negative impact on the Lime Kilns, which are located nearby, we produced a detailed Environmental Impact Assessment.

Recommendations of the assessment included installing vibration monitoring equipment whilst the work was being carried out.

A subsequent amendment to the original proposed plans removed the likelihood of any impact from the works on the Lime Kilns. However, the vibration monitoring was still completed for information purposes.

Appointment of a contractor

The work to carry out the scheme was put out to a competitive tender, and in October 2022 Howard Civil Engineering Ltd were appointed.

Following the successful acquisition of the land, in an exchange between the Council and the National Trust, work started to move the road away from the clifftops in November 2022. 


The project was completed in late summer 2023 and the new road is now in operation.
