This is a neat site worth a look see!
Great photo Jay, thanks for posting.
The Darling Ranges were full of big trees and they had steam sawmills around Perth. The whole of Perth’s roads were made of wood blocks. There were no stone roads. Roads built out of sleepers were called corduroy roads. Generally, there were two sleeper tracks with a span space in between built for horses and carts and trucks with solid rubber tyres.
I drive on a plank road every time I turn into my driveway.
Groan.... Thanks, Dennis "Plank"
Some great information from a area only 20 minutes from where I live and travel that road on a regular basis. City of Cambridge is even closer and it was found and posted on the forum from the other side of the world. My 87 year old Mother remembers plank roads being common place around the suburbs of Perth but being 63 I can't!!:
It would have been well used today with folks heading to the beach to escape the 42Deg (c) summer heat.

That's a different arrangement than I'm used to seeing. Most of the US plank roads I've seen are corduroy style, with the boards laid across the road. The most notable one was across the dunes west of Winterhaven in California.
