History
The Goyder Highway is named after George Goyder, a government surveyor who first identified and mapped Goyder's Line which indicates the northern limit of climatic suitability for intensive agriculture in South Australia. Goyder's Line is near the highway from Crystal Brook to past Burra.
Route
The Goyder Highway starts from the Augusta Highway at Crystal Brook running east then southeast. It is briefly coincident with the Horrocks Highway near Gulnare, RM Williams Way near Spalding and the Barrier Highway near Burra. The highway descends from the Mount Lofty Ranges onto the plains of the Murray–Darling basin. It passes the end of the Thiele Highway at Morgan and continues upstream on the north side of the Murray River to meet the Sturt Highway between Barmera and Monash.
