Main North Road and Nottage Terrace Intersection Upgrade

About the project

The Australian and South Australian Governments have announced $19 million joint funding for the upgrade of the Main North Road and Nottage Terrace intersection, with the costs shared equally.

The Australian Government commitment is part of the Commonwealth Urban Congestion Fund. The State Government’s contribution addresses recommendations of the State Government’s Keeping Metro Traffic Moving Report. The report identifies this intersection as a priority location for treatments that address road congestion and keep traffic flowing.

Main North Road is a key major traffic route, freight route and a high frequency public transport corridor. Nottage Terrace is a key major traffic and primary freight route. This intersection plays a vital role in moving traffic from the north east to the south, bypassing Adelaide’s CBD.

Historical crash data indicates 32 crashes recorded between 2013 and 2017, of which there were ten casualty crashes. The upgrade will:

  • improve travel times
  • improve safety for all users
  • improve network reliability
  • improve economic productivity

Early works are planned to start in 2020.

Planning study and design development: key considerations

Key considerations for the planning study and design development will include:

  • stakeholder and community input and consideration of needs of surrounding businesses and residents including safe access, carparking and managing construction impacts
  • road widening to improve safety and capacity of the intersection
  • turning solutions at the intersection into Nottage Terrace
  • improving travel times to reduce congestion
  • provision of safer pedestrian crossings
  • consideration of bus stops and active transport opportunities
  • consideration of environmental aspects including surrounding vegetation and heritage aspects.
