General Information:
B34 is a route that connects the Adelaide Hills to the Fleurieu Peninsula area, south of Adelaide. It features 3 duplexes: B10 (Adelaide-Mannum Rd) for about 2 km through the town centre of Birdwood, B33 (Adelaide Road) for a few hundred metres at Echunga, and A13 (Victor Harbor Road) for 3 km near Willunga.
The Mount Barker Road section of B34 between Verdun and Hahndorf used to once be the Princes Hwy and used to be numbered NR1 until the 1970s.
The route is pretty much all rural highway / rural road standard and at times quite windy as it makes its way through the Adelaide Hills.
