 The motorway winds relatively steeply down past the site of New Zealand Refrigerating Company's former Burnside Freezing Works, and crosses the Main South Road/Kaikorai Valley Road interchange on a bridge.Once on the flat of the Kaikorai Valley the motorway passes underneath the northbound on-ramp from Green Island before passing between the suburbs of Green Island and Abbotsford to the Green Island/Sunnyvale interchange.Beyond this interchange the motorway crosses the Kaikorai Estuary and bisects the suburb of Fairfield.
