 In 1989-1990 the Green Island motorway was extended northwards up Calton Hill past the Burnside Freezing Works to re-connect with SH1 at Lookout Point.A major extension was completed in 2003 when the 4.5-km Fairfield Bypass was opened.This connected the southern terminus of the Green Island Motorway with the northern end of the Saddle Hill section of SH1.
