The Gregory Highway is a state highway in Queensland, Australia that serves the major coal-mining centres of Central Queensland.[1] The highway was named after Augustus Gregory, an early explorer.
The highway runs southward from Quartz Blow Creek, a point 31km (19miles) west of Mount Surprise on the Gulf Developmental Road, via Charters Towers, to Springsure, over 900km (600miles) away.[2] The northern section of 756km (470miles) is designated by the state government as the Gregory Developmental Road. The shorter southern section between Clermont and Springsure (174km (108miles)) is designated the Gregory Highway. As of 2015, the first 120km (80miles) between the Gulf Developmental Road via Einasleigh to the Lynd Junction are unsealed and may be corrugated. The next section to Charters Towers has been upgraded from single lane to mostly dual-laned bitumen.[2] The road is used by many road trains.
