From Norseman, Eyre Highway takes interstate traffic east across the Nullarbor Plain and into South Australia.
This is primarily mining activities, but also includes pastoral and agricultural exports via Esperance port, tourism to both coastal and inland destinations, and interstate freight traffic, with approximately two million tonnes transported annually along the Great Eastern, Coolgardie–Esperance and Eyre highways.
From the edge of the Wheatbelt, at the Boorabbin National Park, it heads east, to the town of Coolgardie.
Great Eastern Highway, now signposted as Alternate National Route 94, turns north-east, travelling through another 32 kilometres (20 mi) of scrubland to the outskirts of Kalgoorlie.
After 1.9 kilometres (1.2 mi), the highway once more becomes a dual carriageway, and travels past residential neighbourhoods.
