northern connector
project of national significance
• improves road and rail freight access into Adelaide and South Australia’s major port from intrastate regions and interstates
• in accordance with the 30-Year Plan for Greater Adelaide, highly demanded for:• increasing productivity • developing residential land use• linking Southern and Northern industry• reducing greenhouse emissions • separating urban passenger rail services from interstate rail freight
services
• an integral part of Adelaide’s north-south corridor committed to by both State and Federal governments

north south corridor - northern connector
overview - road
• 12 km north of Adelaide CBD
• 15km expressway, 3+3 lanes, 110 km/h
• managed motorway (ITS backbone,
VMS, VSL, incident management etc)
• connects Sturt Hwy and Northern
Expressway with the Port River
Expressway and South Road Superway
• includes staging considerations for
interchange access as traffic demand
grows

north south corridor - northern connector
overview – rail
• 21 km freight rail link between NExy and the Port, overall the new rail
track is approx. 30.9km in length.
• single track with two passing loops, standard gauge
• 6 grade separations in total to facilitate a non-stop road and rail
corridor, including 2 rail overpasses, and 4 road overpasses
• potentially, up to 11 rail crossings can be removed from the existing
rail network
• links with the Adelaide to Perth, Darwin and Sydney rail lines
• growing national export task, particularly mining, requires efficient
link to the Port

interchanges – north, south and waterloo corner
• the northern interchange connects in with the recently completed
Northern Expressway
• southern interchange connects with the south road superway
• connecting the South Road Superway to the Nothern Expressway the
northern connector completes almost 45km of the 78km non-stop north-
south corridor (NEXY (24km), connector (15km), superway (4.8km)

waterloo corner
• the interchange at
waterloo corner
creates east-west and
north-south access
• exit and enter here for
St Kilda, Waterloo

Salisbury, Elizabeth
etc.

development of northern connector
• The preferred option delivers:
• vital link to the Port of Adelaide with intermodal facilities, industrial
clusters and the National Road Network for key intra and interstate
freight movements
• direct contribution to the national objective of addressing freight
capacity constraints
• better use of existing road asset (refer road traffic demand
information – next slide)
• minimisation of impacts on public transport patronage

forecast traffic volumes on northern connector
• the Northern Connector will cater for 55,000 vehicles per day near
Northern Expressway (northern end), and 78,700 vehicles per day near
South Road Superway (southern end) by 2031
• it is predicted that 39,000 north-south trips will be on the existing
network to the east leading to better use of existing road assets and
improved level of service for the Northern Connector
