|The Cahill Expressway, whilst being one named entity, is divided into two sections which perform two very different roles. The southernmost section, passing under the Royal Botanic Gardens and between it and the Domain, is a six lane expressway that forms part of the Metroad 1 route, the Sydney Orbital motorway network and a major through trunk route. In comparison, the viaduct across Circular Quay is a four-lane undivided expressway carrying about a third of the volume of traffic as the Domain section. Since the opening of the Harbour Tunnel, the Circular Quay section has lost its importance as a through route - now providing access to/from the Eastern Suburbs and North Sydney. It is also a prime spot for viewing New Years Eve and Australia Day fireworks extravaganzas! |
The Cahill Expressway will be forever etched in Sydney's history, for many years it was all the Government could show for all the County of Cumberland expressway plans and was the brainchild of Dr. John Bradfield, who designed the Harbour Bridge and planned much of Sydney's electric railway system in the early 20th century.
