A38 Saltash Tunnel

A38 Saltash Tunnel – date confirmed for start of overnight closures.

We’re carrying out a major £25million technology upgrade of the A38 Saltash Tunnel. The works will help keep journeys safe, reliable and reduce the risk of unplanned closures. 

Upcoming works 

Starting Monday 13 January - Overnight tunnel closures 

Starting on Monday 13 January, the overnight tunnel closures will begin as we start working to modernise the A38 Saltash Tunnel.  

From Monday 13 January until the end of February 2025, the eastbound carriageway of the tunnel will be closed on weeknights (8pm to 6am) to enable works in and around the tunnel.  

To limit disruption, our initial closures will only affect eastbound traffic. Westbound traffic will be able to use the tunnel as usual.  

Eastbound traffic will use local diversion routes. The tunnel will be open as normal during the day and at weekends. By closing the tunnel only at night, we can reduce the impact on the local community and drivers.  

At the end of February, the full overnight closures will begin in both directions. We will provide further updates in due course. The overnight tunnel closures will continue until Winter 2025 / 2026.  

Diversions 

From 13 January until the end of February 2025, eastbound traffic will be diverted overnight from Carkeel roundabout via the B3271 and North Road. Occasionally, our works may generate some noise for which we apologise.  

We understand that overnight works can be frustrating, but we thank you for your continued understanding while these essential works take place. Please plan ahead and allow extra time for your journeys.  

As with any complex scheme, dates are subject to change. As we move through the scheme, dates will be announced and kept up to date on our dedicated webpage. Please check online for the latest information. You can also sign up via the webpage to receive notifications when new information has been added. In addition, you can also check our daily closures page or find live travel information on our Traffic England website. 

We continue to work closely with a wide range of stakeholders while we confirm the full programme of works for next year. We will share this information with you once it becomes available.  

We apologise in advance for any inconvenience caused but thank you for your continued understanding.
