It is 7 kilometres (4.3 mi) long and links Rivervale and East Perth with West Perth, bypassing Perth's central business district. It was named after the Australian rules footballer, Graham "Polly" Farmer, who played between 1953 and 1971 in both the WAFL and VFL leagues.
The freeway incorporates Western Australia's only freeway tunnel, the Northbridge Tunnel. The 1.6-kilometre (1 mi) tunnel has two traffic lanes and an emergency stopping lane in each direction, with an escape passageway between the carriageways. The tunnel is colloquially known as the "Polly Pipe", a reference to the freeway's namesake, also humorous because "Poly Pipe" is a colloquial reference to plastic pipes (commonly made from polyethylene or polyvinyl chloride materials) used in reticulation and plumbing. Both tunnel portals feature public art installations. At the western end there is a pictorial history of Northbridge, and at the eastern end the Aboriginal artist Ron Corbett created images based on indigenous artwork. The transportation of dangerous goods and explosives through the freeway tunnel is prohibited.
Micro cache only has log and no writing stick... byo.
NB: there is no need to climb up on anything nor go into the tunnel!
Enjoy!
