A38 daytime lane closures for surveys

We're carrying out essential surveys on the A38 between Tamar Bridge roundabout and Forder Valley.  

These routine surveys help us to ensure that the region's roads are fit for now and the future. Our works will also reduce the risk of future unplanned closures.   

One lane will be closed in each direction on the A38 on Sunday 25 January (7.30am – 6pm) between Tamar Bridge roundabout and Forder Valley.  

For a short period of time in the morning, the westbound lane closure will also extend up to the Marsh Mills junction. 

Significant delays are expected so please:  

o    consider using alternative routes   

o    If you choose to travel, plan ahead and allow plenty of time for journeys 

We understand lane closures can be frustrating. These surveys need to be undertaken during daylight hours. We'll be working at the weekend as this is when there's the least amount of traffic on the road. By working this way, we can complete the surveys as safely and efficiently as possible, with overall less disruption to the travelling public. 

This work is subject to favourable weather conditions. If we're unable to complete our work as planned, we may need to return to complete the surveys at a later date.
