Gregory Highway

The Gregory Highway is a state highway in Queensland, Australia that serves the major coal-mining centres of Central Queensland. The highway was named after Augustus Gregory, an early explorer.

Route description

The highway runs southward from Quartz Blow Creek, a point 31 kilometres (19 mi) west of Mount Surprise on the Gulf Developmental Road, via Charters Towers, to Springsure, over 900 kilometres (560 mi) away. The northern section of 756 kilometres (470 mi) is designated by the state government as the Gregory Developmental Road. The shorter southern section between Clermont and Springsure (174 kilometres (108 mi)) is designated the Gregory Highway. As of 2015, the first 120 kilometres (75 mi) 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. The road is used by many road trains.

Northern Australia Beef Roads upgrades

The Northern Australia Beef Roads Program announced in 2016 included the following project for the Gregory Developmental Road.

Roads of Strategic Importance upgrades

The Roads of Strategic Importance initiative, last updated in March 2022, includes the following projects for the Gregory Highway.

Corridor upgrade

A lead project to upgrade the Townsville to Roma corridor, including sections of the Carnarvon, Dawson and Gregory Highways and surrounding state and council roads, at an estimated cost of $125 million, commenced construction of some work projects in 2020. Planning continues for other projects.

Intersection upgrade Capricorn Highway

A project to upgrade the intersection with the Capricorn Highway in Emerald at a cost of $7.9 million is scheduled for completion in mid-2023. This project was targeted for "early works" by the Queensland Government.

Pavement strengthening and widening

A project to strengthen and widen sections of pavement on the Gregory Developmental Road between Charters Towers and The Lynd at a cost of $15.3 million is planned to be completed in mid-2023. This project is targeted for "early works" by the Queensland Government.

Other upgrades

A project to widen and strengthen 7 kilometres (4.3 mi) of pavement between Marble Creek and Christmas Creek, at a cost of $45.41 million, was due to be completed in late 2023.

A project to upgrade a culvert near Porphyry Road, at a cost of $5,1 million, was due to be completed in late 2023.

Proposals

The Queensland Inland Freight Route is a proposal to upgrade the existing highways from Charters Towers to Mungindi. This would involve significant upgrades to the Gregory Highway between Charters Towers and Springsure.
