Portfolio — 25 August 2026

The Minister for Infrastructure, Transport, Regional Development and Local Government, Catherine King, used today's media releases to highlight two infrastructure milestones — a completed regional bridge upgrade on the Bruce Highway and a construction-phase acceleration on Adelaide's T2D project [TA-260825-infras-044f02702a8b:m00AMR] [TA-260825-infras-ecdd10d051ab:m00AMR].

Both announcements extend the infrastructure agenda the Minister advanced in the 20–21 August updates, continuing the portfolio's pattern of pairing regional delivery with major urban motorway investment.

**Bruce Highway bridge upgrades**

The Minister announced the completion of upgrades to the Station Creek and Boyne River bridges on the Bruce Highway near Benaraby. The works comprised concrete, steel and barrier repairs funded jointly by the Australian Government at $11.04 million and the Queensland Government at $2.76 million [TA-260825-infras-044f02702a8b:m00AMR]. The Australian Government's contribution represents the larger share of the $13.8 million total project cost, at 80 per cent.

**T2D tunnel boring milestone**

The Minister also reported that three tunnel boring machines are now operating simultaneously on the River Torrens to Darlington (T2D) project in Adelaide. The $15.4 billion joint venture between the Australian and South Australian governments aims to deliver a non-stop South Road by 2031 [TA-260825-infras-ecdd10d051ab:m00AMR]. The simultaneous deployment of three TBMs marks a construction-phase milestone for one of the country's largest urban road projects.

**Portfolio trajectory**

Both projects rely on joint federal–state funding arrangements, underscoring the portfolio's approach to advancing infrastructure through shared investment. The contrast in scale — $13.8 million for the Bruce Highway bridges against $15.4 billion for T2D — illustrates the breadth of the portfolio's delivery agenda, from targeted regional bridge repairs to major urban motorway projects [TA-260825-infras-044f02702a8b:m00AMR] [TA-260825-infras-ecdd10d051ab:m00AMR].
