A gantry spanning the motorway with blue overhead signs indicating two lanes exiting and two continuing ahead, and the following text.
Left-hand two lanes destinations: A30 Bodmin; Okehampton .
Right-hand two lanes destinations: Plymouth A38; Torquay (A380).
Junction number: 31.
Three lanes widen to four as the motorway curves through a deep rock cutting, and we arrive at Pearce’s Hill Interchange, the end of the line. From here the motorway divides into A30 and A38 - both will take you onward through Devon to Cornwall.
