General Information:

National Route 1 is a mostly somewhat coastal route in Western Australia. In some cases it travels quite close to the coast and the Indian and Southern Oceans and at other times it is further inland, but still generally following the coastline.

The quality of the route varies from rural 2 lane highway to multi-lane suburban arterial road and also freeway standard.

History:

Forrest Highway:
30 June 1995: Work started on the extension of dual carriageway from Springhill Road near Binningup to the Myalup turnoff. 2
17 June 1996: Dual carriageway section from Harvey to Myalup opened to traffic. 3
1997: Duplication of the Preston section of the Old Coast Road, about 50 kilometres north of Bunbury. 4
2000: The dual carriageway of Old Coast Road was extended up to Lake Clifton. 5
September 2009: Completion of construction works for intersection with Forrest Hwy (SR2) and Peppermint Grove Rd at Lake Clifton.
June 2014: Forrest Highway name extended and as a result of a Landgate decision, now runs from the end of Kwinana Freeway near Mandurah to the Eelup Roundabout in Bunbury, renaming Australind Bypass and one section of Old Coast Road. The decision to rename 57 km of the road was made to clear up confusion caused by the road's three names. 6
Old Coast Road, Dawesville Bypass and Mandurah Road:
1878: Ferry across Peel Inlet at Mandurah discontinued. 7
1894: Construction of first bridge over Peel Inlet at Mandurah. 7
17 April 1953: Replacement bridge over Peel Inlet at Mandurah opened by then Minister for Works, John Tonkin. The bridge is 184 m long and 6.7 m wide, and the concrete piles used in construction are each 18.3 m long and weigh 10.10 tonnes. 7
1969: Old Coast Road seal completed. 8
1986: Mandurah Bypass completed. 8 A new bridge over the estuary opened as part of the bypass. 9
1989: A 7.2 kilometre-long second carriageway through Halls Head and Falcon was opened to traffic. 10
2000: Construction of the dual carriageway Dawesville Bypass around eastern Dawesville. 5
July 2001: Opening of Dawesville Bypass. 3

This sign has since been replaced and also no longer a standard sign in WA.
