NT Gov $37.4M Santa Teresa Road upgrade: design and flood risk notes for engineers
Reviewed by Tom Sullivan

First reported on Roads & Infrastructure (AU)
30 Second Briefing
A $37.4 million Northern Territory Government contract has been awarded to Exact Contracting to seal 22.5 kilometres of Santa Teresa Road, the primary link between the Santa Teresa community and Alice Springs. The unsealed section, which services multiple pastoral leases and several freight operators, has been historically prone to flooding and closures, disrupting heavy vehicle access. Pavement design, drainage capacity and flood immunity will be critical, given the road’s role as the main freight and community access corridor in a remote arid environment.
Technical Brief
- Construction staging will need to maintain access for freight and community traffic during sealing operations.
- Safety management will focus on heavy vehicle interactions, worksite traffic control and dust suppression during earthworks.
- Remote location drives requirements for robust logistics, on-site plant maintenance and contingency planning for weather delays.
- Upgraded geometry and surface condition are expected to reduce crash risk and vehicle damage on the route.
Our Take
The Northern Territory Government has also recently let smaller safety-focused road contracts, such as the $1.81 million Stuart Highway–Bees Creek Road upgrade and the $12.95 million Sandover Highway restoration, signalling a sustained pipeline of regional roadwork where firms like Exact Contracting can build a track record.
In our infrastructure coverage, the NT Government increasingly appears as both a road builder and a supporter of mining and critical minerals (e.g. Tivan’s Molyhil tungsten work and lithium exploration funding), so sealing Santa Teresa Road is likely to be viewed not just as a safety project but as enabling future resource and pastoral logistics south-east of Alice Springs.
