Eyre Highway Widening and Upgrade – Business Case


A business case will be undertaken into the costs and benefits arising from a series of works to provide access for Performance-Based Standards (PBS) Level 4A vehicles (triple road trains) from the Western Australian border through to Port Augusta.

The proposed works to be considered in the business case include widening of intersections in Ceduna and Thevenard, and the widening and realignment of the intersection of the Eyre Highway and Lincoln Highway to provide priority to vehicles travelling on the Eyre Highway.

The business case is jointly funded (on a 50:50 basis) by the Australian and South Australian governments ($1 million each).
