South West - Maintenance schemes

We recognise the environmental value of trees, and manage our trees through their whole lifecycle, to control safety risk and optimise the environmental value provided by trees. 

In the South West we manage a large estate including significant areas of woodland by the side of our roads. Our tree specialists carry out regular inspections for safety and general woodland management. 

We also have a legal obligation to ensure our strategic road network remains safe to road users and the trees in our care do not pose a hazard to adjacent property. Where possible we will make trees safe, and as a last resort remove dead or dying trees when advised to do so by our specialists. 

Ash dieback is significant across the South West region, it has spread rapidly to the trees alongside our roads over recent years. 

Regrettably, surveys by our specialists have found dry conditions and increased temperatures have increased stress on already diseased trees and many ash trees are deteriorating quickly. A large proportion are now dead or dying and pose a potential safety risk, leaving us with no alternative other than to make them safe or remove them. 

Over the coming months, we will remove or make safe ash trees identified for urgent action. We will also be replanting trees in some locations. 

We will be removing and replanting in the following locations: 

• The A30 between Whitecross, Cornwall, and Shillingford Abbot, Devon. 
• The A38 between Tamar Bridge and Exeter. 

The tree work along the A30 will start on Tuesday 22 April and will last approximately 6 weeks. 

The tree work along the A38 will be carried out in two phases: 

• Phase one (Tamar Bridge to Lee Mill) will start on Monday 19 May and will last approximately 7 weeks. 
• Phase two (Lee Mill to Exeter) will start on Monday 3 November and will last approximately 5 months. 

The work will take place overnight. 

Traffic management will include a combination of lanes closures and complete carriageway closures depending on the work taking place. If needed, diversion routes will be fully signposted. 

Ash dieback is a national issue and more information from the Forestry Commission can be found. 

Also, please refer to the Tree Council - Ash dieback a tree owners guide 

We’re refreshing road markings and replacing cat's eyes at various locations along the A30 between Exeter and Penzance. 

We’ll be working on weeknights (8pm – 6am) between Monday 30 June and Wednesday 30 July. This is when there is less traffic on the road. 

The A30 will be open as usual during the day and at weekends.

We’ll carry out this work in phases and will be using a mixture of:

• overnight (8pm to 6am) lane closures
• short sections of overnight carriageway closures (8pm – 6am)
• temporary traffic lights
• convoy systems - you'll be escorted through works behind a one of our vehicles at reduced speed

If we need diversions, they'll be fully signposted. 

Please plan ahead and allow extra time for your journeys.

Dates may change at short notice due to poor weather conditions or operational reasons. If we’re unable to complete our work as planned, we may need to continue beyond the dates stated above. 

You can check the latest information on our daily closures page or find live travel information on our Traffic England site. Our travel alerts give details of live incidents on our network.

We’re resurfacing the A30 (eastbound) from Temple Junction through to Colliford. 

We’ll be carrying out this work weeknights (Monday – Friday between 8pm – 6am). This is when there is the least amount of traffic using the road. 

While we’re working, we’ll be using a convoy system on the eastbound A30. This means the A30 is still open, but you will be taken past the working area behind a traffic vehicle at a reduced speed.

The road will be open as usual during the day and at weekends.
