Snowy Mountains Highway works: design and safety notes for road engineers
Reviewed by Joe Ashwell
First reported on Roads & Infrastructure (AU)
30 Second Briefing
Works have commenced on a $6 million upgrade of the Snowy Mountains Highway between Cooma and Yarrangobilly in New South Wales, funded jointly by the Federal and State governments under a broader $36 million Road Safety programme. The corridor is a key freight and tourism route into the alpine region, so works are expected to focus on pavement rehabilitation, shoulder widening and safety treatments at high‑risk curves and grades. Contractors should anticipate cold‑climate asphalt specifications, drainage improvements and traffic management constraints on steep, two‑lane sections.
Technical Brief
- Works sit within a defined $36 million Road Safety programme, enabling bundled corridor-wide treatments.
Our Take
For regional routes around Cooma and Yarrangobilly, similar safety‑tagged projects in New South Wales often prioritise treatments for tourist and freight traffic on steep, high‑altitude sections, which likely means a focus on geometry, drainage and barrier improvements rather than full pavement reconstruction.
Recent commentary in Roads & Infrastructure Magazine’s “Roads Review: Looking Forward” highlights a shift away from mega‑projects towards people‑centred safety outcomes, and this Snowy Mountains Highway package aligns with that pattern by concentrating limited capital on a defined, high‑risk passage.
