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:

South Western Highway & Robertson Drive:
April 2003: Construction of an overtaking lane on South Western Highway between Balingup and Mullalyup. 2
February 2004: Upgrades to South Western Highway near Kirup. Work included construction of a northbound overtaking lane south of the Kirup townsite. The overtaking lane was built near the Cundinup-Kirup Road intersection. 3
2005: Widening of the seal on various narrow sections of South Western Highway between Donnybrook and Bridgetown, from the width of about 6.8 m to a minimum of 8.0 m. 4
October 2007: Work commenced on an upgrade of a 1.8 km section of the South West Highway south of Donnybrook. The work involved the construction and realignment of the highway, as well as widening the road to include sealed shoulders. 5
18 December 2015: Work commences on the upgrade of a 1.67 km section of the South Western Highway from Marginata Dr to the edge of the Donnybrook town centre. The widening project included the construction of two traffic lanes each 3.5 m wide and a 1.5 m painted median to separate oncoming traffic, 1.5m sealed road shoulder on each side and kerbing, and an extra 1m unsealed shoulder in the areas that were not kerbed, dedicated right turn lanes into Irishtown Road, Marginata Road and Golf Club Access. 6
