The text of the info board reads:
“This imposing bridge highlights the engineering skills required to build
the Great Northern Railway from 1878-91, when the line reached Oodnadatta.
The Algebuckina Bridge, which cost £60,000, spans the Neales River, and was
officially opened for traffic from January 6, 1892. Up to 352 men were
employed to build this bridge by a combination of daily work and piece work.
Made of nineteen 30.9 metre spans it is the longest single bridge in South
Australia. The bridge was strengthened in 1926 to carry heavier rail traffic.
It is on the Register of the National Estate and on the State Heritage Register.”
