Northern Connector Adelaide – Facts, figures, pictures and video


The Northern Connector is the brand-new 15.5 kilometre motorway connecting the Northern Expressway to the South Road Superway in Adelaide, South Australia.
The new motorway is the first concrete motorway in South Australia and the widest in the country.
Here’s some facts, figures, pictures and video from the community open day which was held in advance of the motorway’s much-anticipated opening some-time in March 2020.
