General Information:

The Riddoch Highway is a rural highway connecting the major inland town of Keith with South Australia's southeast coast. It also links the two main routes between Adelaide and Melbourne together as well.

The highway is named after Scottish born John Riddoch, who settled in the Penola area in 1861, and established the Penola Fruit Colony in 1890, renamed Coonawarra in 1897. The two-storey mansion Yallum Park was completed for John Riddoch in 1880 and many of the early buildings in the district were opened or had their foundation stones laid by him. He was a local Member of Parliament for many years. 2
