Three men have died in a two-truck crash on South Australia’s west coast. 

A road train and a truck collided on the Eyre Highway, about 27 kilometres west of Yalata, at about 6:45am on Thursday.

A 77-year-old road train driver from the Adelaide suburb of Smithfield died at the scene.

Two people in the second truck — a 25-year-old from New South Wales and a 45-year-old from Victoria — also died.

The major highway has reopened after being closed for most of Thursday while SA Police’s Major Crash investigators examined the scene.

Police say further delays and possible closures of the highway are expected on Friday as the prime movers and trailers are being recovered.

The deaths bring the lives lost on South Australian roads this year to a total of 26.
