Singleton Bypass one-year mark: delivery and scope notes for road engineers
Reviewed by Joe Ashwell

First reported on Roads & Infrastructure (AU)
30 Second Briefing
Major construction on the $700 million Singleton Bypass in New South Wales has reached its one-year milestone, with the new eight‑kilometre alignment designed to divert about 15,000 vehicles per day from Singleton’s CBD. The project will bypass five existing sets of traffic lights on the New England Highway, targeting one of the Hunter Region’s most persistent congestion bottlenecks. For road and civil contractors, the scheme signals sustained demand for pavement, drainage and structures work along a greenfield highway corridor.
Technical Brief
- Major construction has now been underway for one year on the greenfield highway corridor.
- Bypass geometry is configured as an approximately eight‑kilometre rural highway standard route.
Our Take
Within our 184 Infrastructure stories, New South Wales features heavily for road upgrades in the Hunter Region, signalling that the Singleton Bypass is part of a sustained corridor strategy rather than a one-off project.
By removing five signalised intersections through Singleton’s CBD, the bypass is likely to materially improve heavy-vehicle travel times on the New England Highway, which can change freight routing economics for mining and agribusiness operators in the wider Hunter Region.
A $700M road project at the one‑year construction mark typically implies most major earthworks and structures are either underway or committed, so contractors and suppliers in New South Wales should now be positioning for the downstream pavement, ITS and finishing packages over the next phase.
