Australia's Oldest Bridges of their type are in the Island State of Tasmania. Built by convict labour for horse and cart, they are still in use carrying cars, trucks and buses.
Each has unique features. Two have received ground breaking engineering works to conserve them whilst keeping them in service. The third is a gem of carved stonework.
The bridges are Richmond Bridge, Campbelltown Bridge and Ross Bridge.
Each has both material and construction defects which have given continuing problems over their life and which require high level engineering expertise now and into the future.
The bridges are well known for their age, their visual appearance and settings and for being constructed by convicts. Their designers, using the arch concept with its great strength and load carrying ability, have given strong lasting structures capable of carrying vehicular traffic unknown at their time of construction. Their maintenance history has highlighted the lack of technical expertise of their constructors and has required heritage engineers to pay attention to the basics of material science and of structural behaviour.
The design and construction history has been a trigger enabling good conservation practices.
