Pinjar Road

In 2005, the relevant local government body responsible for the road, the City of Wanneroo, realised the importance of the road and the impact it has on the residents in the adjoining suburbs of Banksia Grove, Carramar, Mariginiup, Neerabup and Tapping due to increased traffic.[3] Funding for the realignment was an issue as the responsibility of construction fell to the developers of the adjoining Carramar Golf Course Estate, Peet Limited, and the City's original plans did not call for construction of this road until at least 2008-2009.

In order to expedite construction and relieve traffic pressures, the city agreed to pre-fund construction of the realignment by Peet, enabling the road to be completed and opened midway through 2006. Prior to the opening of this realignment however, the extension of Joondalup Drive from Wanneroo Road to Neaves Road was also completed and opened to traffic. This in turn caused a large number of heavy westbound vehicles to deviate through local roads within Banksia Grove to connect with Joondalup Drive.

As a consequence of this, the City implemented an order to limit the types of vehicles allowed to pass through the suburb[4] and imposed on-the-spot penalties of up to $5,000 for offenders. The need for this order was removed when the City subsequently closed the old alignment of Pinjar Road south of the Joondalup Drive/Neaves Road intersection, and north of the Yandella Promenade (formerly Clarkson Avenue)/Pinjar Road intersection.

After the opening of the new Pinjar Road alignment in 2005, the old Pinjar Road was closed and divided into four distinct parts, completely ending its use as an arterial and distributor road for traffic:

• Old Yanchep Road to Neaves Road - this part was renamed "Old Yanchep Road" for its entire length, but remained otherwise unchanged.
• Neaves Road to Yandella Promenade - this portion was blocked and closed off at both ends, turning it into a very long local road that can only be accessed through a network of smaller roads in Banksia Grove and Mariginiup. The northern half of the road was renamed to "Greenvale Place" and sealed off from Neaves Road by large rocks, while the southern half became "Mornington Drive". 300m of road was ripped up between Mornington Drive and Pinjar Road to prevent its use as a route of travel.
• Yandella Promenade to Ashley Road - like the above portion, this part was blocked and closed off at both ends, but it runs parallel to the new alignment and so still assumes the name "Pinjar Road". Like Mornington Drive, 250m of road was ripped up at the road's southern end.
• Ashley Road to Wanneroo Road - this remained mostly unchanged, deviating west and running into the new alignment just after the Ashley Road junction. The southern part of the road was re-aligned north-westwards to create a right-angled intersection with Wanneroo Road, where traffic lights were installed.

The new Pinjar Road follows the old Pinjar Road route from Wanneroo Road, up until Yandella Promenade, where it deviates from the original junction at Neaves Road, to a large roundabout at Joondalup Drive 2 km further south-west. The road now completely bypasses Banksia Grove and forms a suburb boundary between Banksia Grove and Tapping.

An $8 million project to realign and reconstruct Pinjar Road between Wanneroo Road to Galileo Avenue was undertaken by the City of Wanneroo. The project began in April 2010, with part of the new road opened to traffic in December 2010. Works were scheduled to be completed by December 2011.[5] The works included shifting the southern terminus with Wanneroo road north-east by approximately 260 metres (850 ft).[6]
