National Highways: A38 Saltash Tunnel update (February / March 2026)
Gantries complete - technology installation continuesWe've finished our civil engineering work.
We've now installed all gantries, including one west of Carkeel roundabout and one east of Manadon roundabout.
We're continuing electrical works, installing and connecting 64 electrical cabinets.
Our current traffic management will stay in place while we finish this work.
Once installed, we'll rigorously test the new systems to make sure they're working properly.
What's next
We're about to refurbish the tunnel's east service building.
We'll strip out the original 1980s equipment and install new, modern electrics.
This should take us a couple of weeks.
We expect to switch on the new tidal flow lane control system in spring. We'll complete the full scheme later in 2026.
