In 1934 and prior to construction commencing surveyors were busy conducting baseline surveyors and triangulation surveys to assist with the positioning of the new bridge – known as ‘Kangaroo Point Bridge’ during the entire design and construction stages.
An article about the concern of nearby householders as to where the bridge may be going. Will they be kicked out of their residency, etc.
What is a Triangulation Survey?
Triangulation surveying is the tracing and measurement of a series or network of triangles to determine distances and relative positions of points spread over an area, by measuring the length of one side of each triangle and deducing its angles and length of other two sides by observation from this baseline. Triangulation is preferred for hills and undulating areas, since it is easy to establish stations at reasonable distances apart, with intervisibility.
