At intervals, Hydro Tasmania has structured simple narrow crossing bridges over the Tarraleah Canal number 1. The various vintages of these crossings seem to indicate changing needs over time.
One bridge appeared to be wide enough for some sort of vehicle to cross, but I wondered where the roadway or path was located on the other side.
Occasionally other buildings and solar panels were associated with a bridge.
Once, as part of the bridge package, I saw a special viewing platform.
The one big enough to drive on is a repurposed 40′ flat rack shipping base. So perhaps it’s not there necessarily to be driven on but because its a very cost efficient way to engineer and install a bridge.
Thank you so much for this very informative comment. I could never have known or worked that out – my experience is way too narrow. Considering the lack of any sort of pathway on the other side of the Canal, I like the idea of this bridge’s installation being a matter of efficiency. And it certainly is effective. Thanks again for your information and thoughts.
