The Sturt Highway remained closed ths morning after a fatal two-truck crash near Euston in the far south-western region of NSW yesterday afternoon.
Emergency services were called to the scene at 5.30pm on Wednesday when officers from the Barrier Police District found two trucks had collided.
NSW Police said one driver died at the scene and is yet to be formally identified.
The other driver, a 29-year-old man, was assessed before being taken to hospital for mandatory testing.
One of the trucks was carrying insecticide, and as a result of the collision, caused a chemical spill which Fire and Rescue NSW worked to contain and decontaminate.
A crime scene has since been established and investigations are now underway with the assistance of the Crash Investigation Unit, said police.
The Sturt Highway is closed in both directions at the Murray Valley Highway and drivers are urged to avoid the area.
