As part of its commitment to safety and air quality, National Highways has reduced the speed limit on the A38 between the Saltash Tunnel and the Carkeel roundabout.

The speed limit has been reduced from 70mph to 50mph, with average speed cameras installed to enforce the 30mph limit through the tunnel and on the B3271 and North Road diversion routes.
