Adelaide Tackles Congestion Through Motorway Works and Public Transport Changes

Adelaide commuters face an average congestion level of 55.1 per cent, which is 4.2 percentage points higher than in 2024, and lose 109 hours a year to rush-hour traffic according to TomTom data. The city is responding through major road projects and adjustments to public transport operations managed by state agencies.

North-South Motorway Expansion

The North-South Motorway (T2D) project is underway to deliver 78 kilometres of non-stop, traffic-light-free motorway between Gawler and Old Noarlunga. This infrastructure work is intended to improve flow across Adelaide's main north-south corridor and reduce pressure on surrounding streets. Construction activity is already producing visible effects on daily travel.

Tram Crossing Removals Planned for 2026

In 2026 Adelaide will remove congested tram level crossings and replace them with new overpasses. The changes are designed to improve safety and reliability for public transport users on affected lines while maintaining road access in those locations.

Current Disruptions on South Road and Nearby Routes

South Road restrictions and bus detours on Routes 248 and 248A are in place because of T2D construction and intersection upgrades. Significant bottlenecks are expected at the Gallipoli Underpass off-ramp during peak periods. Drivers and passengers are advised to check updates from traffic.sa.gov.au and adelaide.mynextride.com.au before travelling.

Public Transport Safety Measures

Tougher powers, including indefinite bans for anti-social behaviour, are due to take effect on the Adelaide Metro network. The measures are intended to increase safety for passengers and staff across the system. Details are available through the Department for Infrastructure and Transport channels.

These coordinated steps on the North-South Motorway, tram crossings, South Road works and Adelaide Metro rules reflect the city's current approach to managing traffic and transport reliability. Commuters should monitor official sources for the latest detour and restriction information as projects progress.
