The Northern Growth Corridor covers a region 20 km to 50 km from central Melbourne. This corridor is expected to accommodate signiﬁcant population and employment growth. By 2031, the corridor is forecast to have around 137,000 residents, an increase of approximately 70% from 2020.
Increasing population and employment growth has put pressure on the existing road and rail network in the corridor. The main road access is the Hume Freeway, and the rail access is via the Seymour Line.
The 2019 Australian Infrastructure Audit forecasts that daily vehicle movements on the Hume Freeway would grow from 54,577 in 2016 to 105,682 by 2031.
The Audit analysis shows that both AM and PM peak-period traffic volumes will be at capacity by 2031, causing congestion and signiﬁcant delays along the corridor.
Rail patronage is forecast to increase from 700 to 9,000 trips per AM peak on a weekday.
