Speed Reductions on North East Road and Major South Road Restrictions This Tuesday

Morning Commute Overview

Adelaide commuters should prepare for a mix of infrastructure-related delays and specific public transport changes this Tuesday, 31 March 2026. While major arterial flows remain steady, significant peak-hour restrictions on South Road and new work zones in the Adelaide Hills will require extra travel time. Authorities recommend allowing an additional 10 to 15 minutes for journeys through the western suburbs and the northeast corridor.

T2D Project and South Road Restrictions

The River Torrens to Darlington (T2D) project continues to impact traffic patterns in Torrensville. Motorists are reminded that a permanent traffic alignment is in place between Ashley Street and West Thebarton Road. To maintain flow during the busiest times of the day, several turn restrictions are being strictly enforced:

• Peak-Hour Bans: Right turns are prohibited from West Thebarton Road and Ashwin Parade onto South Road between 7:00 am – 10:00 am and 2:00 pm – 6:00 pm.
• Permanent Restriction: Northbound drivers on South Road are no longer permitted to turn right into West Thebarton Road at any time.
• Speed Limits: A mandatory 40 km/h limit remains active through the construction zone to ensure the safety of crews at the Tunnel Boring Machine launch site.

Hills and North East Road Upgrades

As part of the Adelaide Hills Productivity and Road Safety Package, works have intensified on North East Road. Between Houghton and Millbrook, commuters will encounter speed and lane restrictions. While major resurfacing and line marking are scheduled for the evening starting at 7:30 pm, intermittent day works are expected today. Motorists should be vigilant for traffic controllers and potential lane merges near the Houghton Hollow Road and Blackhill Road intersections.
