Capricorn Highway
Highway in Queensland, Australia
From Wikipedia, the free encyclopedia
The Capricorn Highway is located in Central Queensland, Australia, and links the city of Rockhampton with western Queensland.[1] The highway is 575 kilometres (357 mi) long, and joins the Landsborough Highway at Barcaldine.[2] Formerly National Route 66, Queensland began to convert to the alphanumeric system much of Australia had adopted in the early-2000s and is now designated as A4. The highway runs parallel with the Tropic of Capricorn, hence its name.

Corridor upgrade
A lead project to upgrade the Mount Isa to Rockhampton corridor, including sections of the Capricorn and Landsborough Highways and surrounding state and council roads, at an estimated cost of $237.5 million, was in the planning and scoping stage. Works are expected to include progressive sealing, lane duplications and crossing upgrades.[8]
