It must be very nice to have a handy section of roadway to use as an emergency runway - but if you ever have to land on a road, the problem of overhead wires and road signs that aren't far enough apart to allow wing clearance, are some pretty serious hazards to face!
Many years ago, a business associate departed from YPKG for YCLG in his PA-28, and had fuel tank transfer issues that resulted in engine stoppage. He was unable to restart the engine and did a dead-stick landing on the Coolgardie-Kalgoorlie road (Gt Eastern Hwy).
The roadway was adequate width, and there being no overhead wires in the vicinity, he made a successful landing. However, a roadside advisory sign he couldn't avoid in the landing roll, took a wing off!
