Route B101, Southern Ports Highway, is an alternative coastal route to the Princes Highway between Millicent and Kingston S.E. In fact, until 1933 the current route of the Southern Ports Highway was part of the Princes Highway. The highway was fully sealed in 1978 and thus received the Alternative National Route 1 shield - which was replaced in 1999 by the current B101 designation. As of January 2005 signage was about 50/50 between the number of Alt-1 signs and the number of B101 signs.

The route generally comprises good quality 2-lane rural highway. Motorists are required to turn off to stay on the route at a number of locations as historically the roads radiating from Robe and Beachport were the more important through routes. Southern Ports Highway comprises a collection of roads linking these radial routes.
