Angle Vale Bridge

The Angle Vale Bridge is a significant bridge in Australia, as it is one of the best examples of a laminated wooden arch bridge. The bridge is included in the State Heritage Register.

Using technology originally imported from Europe and America, laminated arch bridges were constructed in many Australian colonies from as early as 1853. In South Australia, the first were built in 1856. In these early bridges, the laminations for the arches were laid up horizontally and then bolted at regular intervals. Fabricated from both imported softwood and local hardwood, the arches were cheap but they had a service life of only 12 to 16 years. Water penetrated between the laminations where it was retained and the timber quickly rotted.

You can read more about the bridge from the Timber building in Australia site and from Engineers Australia
