|Wood was used to weigh down manhole covers too. This gem is in Philip Street outside Football (NRL) headquarters.|
|These two examples, both found in Philip St, show the gradual change from woodblock to bitument and concrete to weigh down manhole covers|
Above is a photograph from The City of Sydney site, showing Castlereagh Street in the early '20s. Part of the road surface has been washed away and spot filled with bitumen, even though the rest of the surface was woodblock.
Below is a section of George St (North) outside the Orient Hotel where a sample of woodblocking has been recently relaid to enable us to see how it used to be. Not far away, through the Argyle Cut and beside the Garrison Church there is a section of road surface where the layers of bitument are washed away during periods of intense raid, exposing the woodblocking beneath.
