National Highways: A38 Saltash Tunnel technology upgrade - upcoming works
We’re continuing our extensive programme of work to update the technology in and around Saltash Tunnel to keep journeys safe and reliable, and reduce the risk of unplanned closures.We’re about to install the last two new electronic variable messaging signs on the westbound A38, east of the Tamar Bridge roundabout.
Once installed, the 50mph speed limit - currently in place on a short stretch of the westbound A38 before the bridge - will permanently change to 60mph.
