Project DescriptionThe New Perth Bunbury Highway (Kwinana Freeway Extension – Forrest Highway) project involved the construction of a 70.5 kilometre four-lane dual carriageway from the previous southern end of the Kwinana Freeway at Safety Bay Road to join the Old Coast Road near Lake Clifton.
The new highway was constructed to a freeway standard from Safety Bay Road to Pinjarra Road (Kwinana Freeway Extension) with the remainder of the route being built as a rural highway (Forrest Highway).
Interchanges have been constructed at Safety Bay Road, Karnup Road, Paganoni Road, Lakes Road, Mandurah Entrance Road and Pinjarra Road.
Intersections have been constructed at Beecham Road, Greenlands Road, Paull Road, Mills Road, Herron Point Road, Old Bunbury Road, Dorsett Road and Old Coast Road.
Bridges have been built to carry the new highway over the Serpentine River, Nambeelup Brook, Murray River / Pinjarra Road, South Yunderup Road, Murray River floodplain, Harvey River and a number of Water Corporation drains. A bridge has been built over the highway at Red Road. BenefitsThe new highway is expected to cut about 30 minutes off the journey between Safety Bay Road and Lake Clifton and provide a high standard link from the Peel and South West regions to Perth's markets and airport.
Regional traffic and long distance haulage traffic will be able to travel along a safe, free flowing route away from built-up areas. Pressure and congestion on the existing coastal route through Mandurah and the South Western Highway will be relieved. FundingThe Australian Government provided $330 million to the project, in partnership with the Western Australian Government. TimetableConstruction commenced in December 2006 and was opened to traffic on 20 September 2009. Photo GalleryRelated LinksMain Roads Western Australia |
