The Stuart Highway is now open with speed restrictions in place following Saturday's fatal crash.
A crash involving a truck and a Ford utility occurred on the highway between Pimba and Glendambo about 12.15pm on Saturday 6 March, with both vehicles then catching fire.
Sadly, the driver of the Ford ute, a 23-year-old man from the ACT, and a passenger in the truck, a 57-year-old woman from Para Vista, died at the scene.
The man driving the truck was airlifted to the Royal Adelaide Hospital in a critical condition.
The highway was closed for several days due to the damage to the road surface.
Major Crash Investigators flew to the scene from Adelaide to investigate the circumstances surrounding the crash.
The two death brings the number of lives lost on our roads this year to 20 compared to 17.
