4 lane road between Gympie and Cairns? Hardly justified and the various govts know it. The Pacific highway quad, not sure if complete took how many years for half the distance and there is 12m who live along its corridor.
Parts of the Bruce highway are only moderately used for some of the day in comparison to the Pacific.
There will never be sleepers again on the rail corridor to Cairns/Townsville again, the CTT is more than adequate and the only deficiencies are lack of 7 days a week running, easily solved by the purchase of another set and significant improvement in running time between T'ville and Cairns. The current average speed is a miserable 50-55km/h between these two cities. Its at least 70-75km/h to T'ville to Brisbane,
In actual fact there are several sections of the two-lane Bruce Highway carrying more than 10,000-vehicles per day and 62% of the two-lane highway between Gympie and Cairns carries more than 5,000-vehicles per day. The Federal Government is currently funding four-laning for the Midland Highway in Tasmania and the Western Highway in Victoria for sections carrying 6,000-vehicles per day.
More than 200 people die on the Bruce Highway every year - one fifth of all Australian road deaths - and the Bruce Highway has made it to the top ten deadliest highways in the world based on road deaths. The Bruce Highway serves a resident population of 1.3-million between Gympie and Cairns - a number that doesn't take into account the tens of thousands of road-based tourists using it each year.
Vehicle numbers between Ayr and Townsville are at 12,000 per day, north of Townsville it's 14,000-vehicles per day and between Innisfail and Cairns it's 16,000-vehicles per day - in any other state these sections would be already duplicated or planning well advanced for such works...apart from this week's policy promise by an opposition party, there is no such planning, except for a section between Edmonton and Gordonvale south of Cairns.
Even on the quieter sections of the highway there are congestion issues caused by slow vehicles, today I ended up driving at 80km/h for nearly 50km in a 110km/h zone near Marlborough behind caravans and wideloads. The 100km section between Kalarka and Marlborough has no overtaking lanes, a situation repeated for northbound traffic between Bowen and Home Hill over a similar distance.
Fortunately for North Queensland, Brisbane is getting another tunnel under the Brisbane River, with some of the works occurring in the current Transport Minister's electorate.
