Major O-Bahn Closure and South Road Realignment to Impact Saturday Commute

Overview of Saturday Traffic

Adelaide commuters should prepare for a significant shift in travel patterns this Saturday, 28 March 2026. While the heavy festival traffic of early March has subsided, major infrastructure projects are entering critical phases. The lead editor for adelaide.news advises those using the O-Bahn corridor or the North-South Corridor to allow at least 20 minutes of additional travel time today.

Significant O-Bahn and Public Transport Disruptions

The most notable impact on public transport today is the planned closure of the O-Bahn track. Adelaide Metro has confirmed that the corridor will be closed between Paradise Interchange and Tea Tree Plaza Interchange throughout Saturday. Passengers are advised of the following:

• Substitute buses will be in operation to shuttle commuters between the affected interchanges.
• Stop W2 on North Terrace (South side) is closed today, requiring passengers to use alternative boarding points nearby.
• The long-term closure of Stop 6A on Sir Donald Bradman Drive (North side) continues through today, impacting routes 163, J1, J2, and AO26.

With the AFL season in full swing, Footy Express services are active for those heading to Adelaide Oval. Commuters are encouraged to use these free services to alleviate pressure on city parking and arterial roads.

South Road and T2D Project Updates

In the western suburbs, the permanent traffic alignment on South Road in Torrensville is now fully operational as part of the River Torrens to Darlington (T2D) project. Motorists must navigate new lane configurations near the Brickworks Marketplace. Key restrictions to keep in mind today include:

• Turning Restrictions: There is a permanent prohibition on right-hand turns for northbound motorists on South Road into West Thebarton Road.
• Heavy Vehicle Limits: Vehicles exceeding 8.8 meters are strictly prohibited from turning right from West Thebarton Road at any time, with detours in place via Port Road.
• Construction Speed Limits: A mandatory 40 km/h speed limit remains in effect through the Torrensville construction zone to ensure the safety of crews working on the Tunnel Boring Machine launch site.

Arterial Roadworks and Regional Delays

Maintenance and resurfacing programs are also active across several other key corridors:

• Greenhill Road: Resurfacing works continue in Burnside between St Albans Drive and the Greenhill Summit Track. Expect lane merges and speed reductions to 40 km/h.
• Torrens Valley Road: Local traffic management is in place between Cuddlee Creek and Gumeracha from 9:00 am to 4:00 pm, which may delay those heading into the Adelaide Hills.
• Marion Road & Anzac Highway: Minor detours persist due to utility upgrades; however, most lanes remain open for weekend traffic.

Drivers are encouraged to monitor real-time traffic apps and follow all posted signage to ensure a safe and efficient journey across the metropolitan area today.
