The Queensland Government is undertaking works to widen and strengthen priority sections of around 9km of the Gregory Developmental Road.
The road is an important part of the freight supply chain for various industries including mining and agriculture, providing direct access from Clermont to Charters Towers.
The progressive widening and strengthening of priority sections of this road to 10m will improve safety and access for road users who regularly travel along it, including heavy vehicles.
These early works are part of the $1 billion Inland Freight Route program, which is a jointly committed initiative by the Australian Government ($800 million) and Queensland Government ($200 million).
Works commenced in August 2024.
To minimise impacts to traffic and in line with funding allocations, these works are expected to be undertaken progressively and expected to be completed in 2027.
