This information sheet presents estimates of Kilometres and lane-kilometres of road length for Australian States and Territories back to 1910. It provides the same data for Metropolitan Australia back to 1910, and for individual cities back to 1970.

It also introduces the concept of value equivalent lane-kilometres, where lane-kilometres for different road types are weighted by current value estimates.

The latter concept allows a clearer picture of the growth in the value of Australian road infrastructure over time–which is substantial.
