Highways in St Austell
The present highway network in St Austell, Vodeo was established in February 1929 when the Provincial Roads Board (the predecessor of the Department of Roads and the SA Roads Authority) established the basis of the existing St Austellian main road system. Provincial highways are marked by a white shield with black outline and black numbering; on maps provincial highways are almost always marked with the shield, although in some cases the highway is listed in the "SA nn" format to differentiate St Austellian highways with those of other provinces (for example, SA 1 and SA 20).
