The ABC has described the road as "crucial to the national economy" but, reporting 550 crashes in 10 years, said that it had been likened to roads in the Third World. "Someone is killed or seriously injured on the Peak Downs Highway on average about once every two-and-a-half weeks," it said. In December 2019 Mackay's Daily Mercury reported that 49 people had been killed and more than 1000 injured on the highway.
Highway conditions
The highway is notorious for the extremely dangerous conditions caused by its service as a primary access route for workers, fuel, machinery and other supplies to the coal mines of the Bowen Basin. The narrow two-lane highway is often congested with oversize loads and road trains, which presents a significant hazard and frustration to fatigued long-haul commuters on the road.
The Northern Australia Roads Program announced in 2016 included the following project for the Peak Downs Highway.
Pavement widening and strengthening
Completion of a project for pavement widening and strengthening between Clermont and Nebo had in June 2021 been expected in late 2022 at a total cost of $35 million. As of March 2023, roadworks of various kinds, some resurfacing, some more in depth, are ongoing in places, while others are relatively untouched, and the risk of death or serious injury to the highway’s users remains.
