The A30 is to be closed for four nights at Chiverton Junction this month as part of its finishing work on the main route and local roads.

The Highways Agency will be implementing some more traffic controls on local roads so it can continue its work to complete the project throughout the autumn.

From Monday October 14 at 9am, it will be implementing lane restrictions on and around the Chiverton gyratory for six to eight weeks. These will operate from 9.30am to 3:30pm each day in two main phases.

These restrictions will be in place so that it can finalise work on the retaining walls around the junction and allow the workforce to do this safely.

The first phase will narrow the A390 approach to Chiverton to one lane, and the second phase will narrow the A3075 and B3277 approaches to one lane.

There will also be reduced lanes available on the roundabout itself in order to manage traffic joining and leaving the A30, or accessing local roads.

Through traffic on the new A30 dual carriageway will not be affected by these restrictions.

Drivers are being warned to plan ahead and allow extra time for their journeys during these works.

There will be overnight closures on the A30, eastbound only, starting on Monday, October 14 for up to four nights. Closures will run from 8pm until 6am.

The signed diversion route will take traffic off at Chiverton Junction and follow the A3075 to Goonhavern, then the B3285 to re-join the A30 at Carland Cross Junction.

“Please allow extra time for your journeys and take extra care when driving at night,” said an agency spokesperson.

Looking further ahead, there are several key closures planned as follows: * Night-time closures of Carland Cross Junction and a joint closure of part of the A39 with Cornwall Council during the week commencing 21 October.

* A full closure of the B3284 north starting the week commencing 28 October.
