The section of the Murchison Highway between Pieman Road and Cradle Mountain Link Road forms a critical transport link between the majority of west coast townships and the north coast and is a High Productivity Vehicle/Higher Mass Limit (HPV/HML) gazetted route. This section of the Highway has narrow geometry, limited overtaking facilities and has experienced high crash statistics in discrete locations.
The objective of the project was to improve the safety for all road users, strengthen the pavement and provide geometry suitable for HPV’s.
The works are staged across a total of seven sections scheduled for completion over a period of almost two years including periodic shut downs to allow for seasonal changes. Works have been planned and coordinated to be completed under traffic providing safe and constant passage for the traveling public throughout the life of the project.
