[edit] History

Marmion Avenue was first created as an arterial road that tracked the then-new outer northern suburbs of Perth, following the outer northern limit as it expanded. Its namesake, the suburb of Marmion was the start of the road in the late 1960s, when it was an arterial road from Warwick to then-remote Mullaloo Beach. Until the early 1980s, the road was a single carriageway. In 1984-85, West Coast Highway, the main road from Scarborough and Fremantle, was brought inland from Pearl Parade and joined to the end of Marmion Avenue at Karrinyup Road, and Marmion Avenue - now the most important road in the coastal suburbs - was dualled to Whitfords Avenue. In early 1986, it was assigned State Route 71, and from then on, it was gradually extended as a single carriageway road further north - extending first to Ocean Reef Road, then Shenton Avenue, Burns Beach Road and then in the mid-1990s fully extended to Quinns Rocks. Marmion Avenue was completely dualled in 2001, with the last portion being the empty stretch between Burns Beach Road & Quinns Rocks. Marmion Avenue is an important road for those in the northern suburbs, especially those living beyond the end of the Mitchell Freeway and in the broader suburban region of Joondalup. It is generally referred to by locals as just "The Marmion" or as "Marmion Av".

[edit] Future Extensions

At present, Marmion Avenue ends at Kingsbridge Boulevard in Butler (part of the Brighton Estate), and was due to be constructed as a single carriageway to Yanchep in 2004. The extended stretch will finish at the large roundabout at Yanchep Beach Road and Lagoon Drive, Yanchep. As of September 2006, it is still in the planning stages.

The completion will allow the future Satellite city of Alkimos/Eglinton to start construction. Currently the extension is being delayed due to disagreements at State Government level about what route the road should follow. This extension will be built in one go as a single road with no intersections past its present terminus, serving as a link to a growing Yanchep. Extensions after this are possible to Two Rocks, however there are no plans for this at present - one possible complication would be Two Rocks's past use as a munitions dump, meaning that most non-suburban sections of the suburb are fenced off.

[edit] Major Intersections

Marmion Avenue starts at the end of West Coast Highway at the Karrinyup Road intersection in Trigg, and currently ends at the Kingsbridge Boulevard & Jindalee Boulevard Junction in Butler/Jindalee. All major intersections are controlled by traffic lights, or in some cases very large roundabouts.
