Great Eastern Highway

The Great Eastern Highway is a major road between the Western Australian cities of Perth and Kalgoorlie. It is a key route for vehicles accessing the eastern wheatbelt and the eastern goldfields. It also forms the westernmost 595 kilometres (370 mi) of the main road transportation link between Perth and the east coast of Australia.

The road is mostly a federally funded national highway due to its national strategic importance. It is signed as National Highway 94 except for a 9 km stretch between the Great Eastern Highway Bypass and Roe Highway, and the 40 km section between Coolgardie and Kalgoorlie. It is also signed as National Route 1 between The Causeway and Morrison Road; State Route 51 between Johnson Street, Guildford, and Roe Highway; and Tourist Drive 203 between Terrace Road, Guildford and Morrison Road, Midland.

The highway mostly runs in parallel with the Mundaring to Kalgoorlie water pipeline, which pipes drinking water drawn from Mundaring Weir near Perth 600 km east to Kalgoorlie. The highway was sealed by 1954. Two highways spur off Great Eastern Highway at various stages; at Perth's eastern metropolitan boundary the Great Southern Highway begins, which links Perth to such towns as York, Brookton, Narrogin, and Katanning, and 40 km prior to arrival at Kalgoorlie the Coolgardie-Esperance Highway begins, which serves, among others Norseman, Esperance, and the east of Australia.
