Abernethy Road is a 14.7-kilometre (9.1 mi)[clarification needed] long minor arterial road linking Belmont with the Great Eastern Highway Bypass in Hazelmere, a suburb of Perth, Western Australia. It runs along the eastern boundary of the Perth Airport area. It serves as an alternative access road for Perth Airport (via Grogan Road), and provides the foothills suburbs with alternative access to the Perth central business district. In 2014, an on-ramp joining with Tonkin Highway where Abernethy Road passes underneath was constructed, as part of Gateway WA.
