Route Overview:

This section of Princes Highway, from Tailem Bend southeast to the Victoria Border, is the least important section of Highway One in South Australia. So much so that part of it has even received the B1 designation - rather unusual to see Highway One defamed in such a way. Thus, between Mt Gambier and Tailem Bend the Princes Highway is B1 and east of Mt Gambier it is again A1.

Not much major work has been done on this road to speak of. It was fully sealed, albeit narrowly over much of its length, by 1955, when it gained the National Route 1 shield. The alignment in Mount Gambier was shifted onto what is known locally as Jubilee Highway (from Commercial Street) in the 1970s (not 100% sure on this one) and a deviation bypassing the town of Glencoe was constructed in the 1980s. In 1998 Transport SA replaced National Route 1 with the B1 and A1 designations, howver, many NR1 signs still remain.

A feature of the highway is the journey hugging the coastline and The Coorong between Kingston and Meningie. During 2003 and 2004 Transport SA undetook some pavement rehabilitation and shoulder widening along The Coorong making it a much more pleasant journey.

The Princes Highway has dual carriageway conditions through Mount Gambier and east to the Glenelg Highway junction.
