Because we are starting to plant trees along the creek line - we need to get across.
The main cost in constructing this bridge was the bolts.
I had obtained three pieces of 150mm Z purlin from the tip for $10
I cut these up and welded them together to create two lengths approximately 5m long.
Then I reinforced the joins by bolting on some angle iron, top and bottom, over the welds.
The Z purlins are held in a vertical position using 4 spacing rectanges constructed from bed frame angle iron.
Then to stop sideways oscillation I also bolted in diagonal braces
Each end was also bolted down to some large, heavy PFCs to act as landings.
Still need to attach some cladding - either floor boards or multi-ply with appropriate paint coating
Many thanks to Ross for helping us haul the bridge across the creek and bolting on the landing
