The Kennedy Highway is a highway in northern Queensland, Australia. It runs as National Route 1 for approximately 243 km from Smithfield, on the northern outskirts of Cairns, to the Gulf Developmental Road in the vicinity of Forty Mile Scrub and Undara Volcanic national parks (at Minnamoolka, about 40 kilometres south of Mount Garnet).[1] South of this junction, the road continues as the Kennedy Developmental Road (State Highway 62) to Boulia about 936 kilometres away, via Hughenden. West of the junction, National Route 1 continues as the Gulf Developmental Road to Normanton.
From Smithfield, the highway climbs up into the Atherton Tableland before heading in a general south-westerly direction to the aforementioned junction. The highway is mostly two-lanes. Major towns on, or just off, the Kennedy Highway include Smithfield, Kuranda, Mareeba, Atherton, Ravenshoe and Mount Garnet. Past Mount Garnet, the Kennedy Highway has several long sections of single lane bitumen. The section between The Lynd Roadhouse junction at Conjuboy and Hughenden is mostly unsealed and is also known as the Hann Highway.[2]
For a distance of more than 100 km, from the crossing on the Diamantina River to a point southwest of Middleton, the Kennedy Developmental Road passes across a roughly circular zone measuring some across that has been identified by Geoscience Australia as a crustal anomaly, the Diamantina River ring feature. Proof is currently lacking as to the cause, but it is believed likely that the anomaly was caused by an asteroid strike that happened about 300 million years ago.[3]
Two northern councils (Etheridge and Flinders) have proposed development of the Hann Highway which would allow for the transport of products from Far North Queensland to markets in New South Wales and Victoria considerably quicker than via existing coastal routes which have rougher terrain and are sometimes impassable due to floods.[4]
The Northern Australia Roads Program announced in 2016 included two projects for the Kennedy Developmental Road.
The project for widening a section of road from a one-lane seal to a two-lane seal between Mount Garnet and The Lynd was completed in early 2018 at a total cost of $3.3 million.[5]
The project for upgrading sections of the road between The Lynd and Hughenden was completed in early 2020 at a total cost of $47.9 million.[6]
The Roads of Strategic Importance initiative, last updated in March 2022, includes the following projects for the Kennedy Developmental Road.
A lead project to upgrade the Queensland section of the Tennant Creek to Townsville corridor, including sections of the Barkly and Flinders Highways, the Kennedy Developmental Road and surrounding state and council roads, at an estimated cost of $250 million, was in the planning stage in 2020.[7]
A project for progressive sealing of a section of the Kennedy Developmental Road between The Lynd and Hughenden at a cost of $50 million is planned to be completed by mid-2023.[8] This project is targeted for "early works" by the Queensland Government.[9]
A project to strengthen and widen about 5km (03miles) of the road (Outback Way) between Winton and Boulia, at a cost of $4.825 million, was completed in September 2020.[10]
A project to plan the upgrade of the Barron River bridge, at a cost of $2.1 million, was to be completed in late 2022.[11]
A project to install Intelligent Transport System (ITS) treatments on Kuranda Range Road, at a cost of $30 million, was due to completed by late 2022.[12]
A project to provide targeted road safety improvements between Mareeba and Tolga, at a cost of $37.5 million, was due for completion in mid 2022.[13]
A works program of six projects to provide road safety enhancements between Kuranda and Mareeba, at a cost of $45 million, was expected to complete in early 2023.[14]
