South West - Maintenance schemes

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

We began a programme of Ash Dieback removal in 2022. Although the issue still requires careful monitoring, we have now completed most of our clearance work. Over the coming months we will begin replanting the areas most affected by this work. We will plant just over 3,000 new trees along the A30 in Devon and Cornwall, ahead of bird nesting season. Local species such as Hazel, Crab Apple, Holly, Hawthorn, Honeysuckle, European Spindle, Hornbeam and several others in lesser numbers, will be planted in a variety of sizes. The trees have been carefully chosen to ensure local habitats are encouraged to flourish.

The work will take place on verges with some rolling lane closures in place.

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

We’re carrying out repairs and maintenance to the Avers Interchange on the A30 at Redruth.

Working on the roundabout above the A30, we’ll be repairing and replacing expansion joints, resurfacing and waterproofing. This will maintain and improve safety for everyone using this busy junction.

Our work will start on Monday 9 September. It will take up to ten weeks. We’ll be using a mixture of lane and full closures to allow us to work as safely and quickly as possible, with least disruption.

Closure information

From 7am on Monday 9 September, the Avers Interchange roundabout over the A30 will be closed:

between the eastbound entry and westbound exit
between the westbound entry and eastbound exit

The A30 will remain open as usual through the junction.

Diversion

Diversion routes will be in place for eastbound traffic wanting to access Redruth and westbound traffic going towards North Country by travelling to the next junction and returning.

A30 Avers Interchange diversion map – once you’ve opened the map, select the route you want to show from the list on the left hand side.

Please plan ahead and allow extra time for your journey.

The roundabout is due to fully reopen in late November, however this work is subject to favourable weather conditions, for example heavy rain may affect the progress. We’ll be posting updates on our webpage.

Fully closing sections of the roundabout for solid blocks of time means we can reduce the time needed for this work from nine months to ten weeks.

Pedestrian and cycle shuttle bus service – North Country to ALDI

As we’re unable to allow pedestrian or cycle access through the closures, there will be a shuttle bus service running between North Country and ALDI from 7am to midnight each day. Please note this is subject to change depending on demand. 

We’re resurfacing the A30 between Dunheved and Trebursye. This will maintain and improve safety for everyone using the road, and reduce the need for any unplanned closures.

Closure and diversion routes:

Diversion: use the A388.

Wednesday 20 to Wednesday 27 November:

The westbound entry slip at Pennygillam will be closed and we’ll be using a convoy system on the 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.

Diversion: use the eastbound A30 leave via the eastbound Tavistock Road exit slip onto Tavistock Road, where you can join the westbound carriageway.

Thursday 28 November:

Please plan ahead and allow extra time for your journeys. 

We’re currently upgrading a number of weather stations on our road network to maintain safety and improve the journey for road users. We use roadside weather stations to collect information like road temperature and atmospheric conditions.

As part of these upgrades, the following works will be taking place on the A30 eastbound carriageway at Highgate / Indian Queens junction:

11 November to 05 December

There will be overnight lane closures of the A30 eastbound carriageway at the Highgate / Indian Queens junction (8pm to 6am excluding weekends).

There will be a  full overnight eastbound closure of the A30 at the Highgate / Indian Queens junction from 8pm – 6am.  A very short diversion will be in place via the Indian Queens exit slip, before rejoining the A30 via the eastbound Indian Queens entry slip.

The road will be open as usual during the day.

We will also be returning to the site on various dates in December and January to finish our works and to ensure the technology is working as it should.
