All three highways carry on concurrently for 2.4 kilometres (1.5 mi) into Kerrobert.

Highway 31 travels east from 21 passing through Millerdale, Dodsland, and Druid en route to the village of Plenty,[8] at which point it turns south for about 9.7 kilometres (6 mi) before resuming its eastward travel.
