Researchers should be wary of historic street locations as the streets of Ballarat and surrounds have been renumbered over the years.
Plank Road was a street in Ballarat, Victoria from 1858-1868. Before 1858 it was called Main Street, and after 1868 it was known as Main Road. It becomes Geelong Road south of the city. There is considerable overlap in the use of the names through the years.
Origin of the Name
The Plank Road was named because it was built with a surface of wooden planks. James Darby built the Plank Road in the 1850's:
One of the first contracts undertaken by him was the construction of the 'plank road' connecting Ballarat East with the northern boundary of what is now known as Buninyong Shire. His line of planks carried for many years the heavy traffic between Geelong and Ballarat, and was finally replaced by ordinary road metal.
