$51m investment in Adelaide Intersections

By on 12 June 2019

Adelaide is set to receive massive intersection upgrades, with a $51 million investment from the South Australian Government in the 2019-2020 state budget. The upgrades will take place in the northern suburbs with the intention of improving traffic flow on Main North and Grand Junction roads.


The multi-million-dollar investment will include:


  • $19 million to upgrade the intersection of Main North Road and Nottage Terrace. This intersection caters to 66,000 vehicles daily and suffers congestion during peak hours. The addition of a new right-hand turning lane on Main North Road and an extended bus lane is planned to help the flow of traffic.


  • $13 million to upgrade the intersection of Main North, Kings and McIntyre Roads. 78,000 vehicles pass through this intersection daily, including major freight vehicles and public transport. An extension or addition of right-hand turning lanes has been proposed to improve safety and efficiency.


  • $19 million to upgrade the intersection of Grand Junction, Hampstead and Briens Roads. With approximately 58,000 vehicles utilising this intersection, an increase in capacity is set to take place.

“These are some of the most congested intersections in Adelaide northern suburbs accommodating between 58,000 and 78,000 vehicle per day and nearing operational capacity.


“Aside from being major arterial roads for the public, they are also key routes for freight traveling through to the north of the city,” Minister for Transport, Infrastructure and Local Government Stephan Knoll said.

“We’re investing $51 million in the next State Budget, in partnership with the Commonwealth Government, to build these intersections, so that South Australians spend less time stuck in traffic and have a faster and safer journey into work or home.”


Early works are expected to begin within the 2019-20 financial year.
