Graham Farmer Freeway is a inner-city freeway in Perth, Western Australia. It links Rivervale and Burswood with West Perth and Leederville, providing an east-west bypass of Perth's central business district. The freeway, in conjunction with Great Eastern Highway and Orrong Road, is also an important connection between the city centre and Perth Airport. It is allocated State Route 8, and was named in honour of the Australian rules footballer, Graham "Polly" Farmer, who played between 1953 and 1971 in both the West Australian and Victorian Football Leagues. Route description Western terminus The freeway's western terminus is a hybrid interchange, combining a Full Y interchange with the Mitchell Freeway, an exit to James Street, and an entrance ramp from and exit ramp to Loftus Street. The interchange also incorporates a partial Y interchange that connects Charles Street to the Mitchell Freeway. This is known as the Hamilton Interchange. Northbridge Tunnel Immediately east of the interchange is the Northbridge Tunnel, Western Australia's only freeway tunnel. The tunnel has three traffic lanes in each direction, with an escape passageway between the carriageways. The tunnel is colloquially known as the "Polly Pipe", a reference not only to the freeway's namesake, but also to the colloquialism "Poly Pipe" in 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. Perth City exits At the eastern end of the tunnel is the diamond interchange with East Parade, which connects the freeway to East Perth. The East Parade exit ramps allow traffic movements to the opposite entrance ramp, as the westbound entrance ramp also connects to Lord Street, whilst the eastbound exit ramp merges with a ramp from Lord Street. This allows a connection between the city centre and the freeway, via Lord Street. Windan Bridge The freeway then crosses the Swan River over the , six lane Windan Bridge. The bridge is one of the more recent constructions of the 19 bridges that cross the river. It includes pedestrian and cycling access. Burswood Graham Farmer Freeway continues into Burswood as a six lane freeway. There is a diamond interchange with Victoria Park
