Buses Replace Sunday Morning Trains; Speed Reductions on M1 at Mount Ousley

Sunday Morning Rail Disruptions

Commuters and weekend travelers on the South Coast Line should prepare for significant service changes this morning. Transport for NSW has confirmed that on Sunday, 15 March 2026, buses will replace trains between Bomaderry, Port Kembla, and Wollongong. These replacement services are scheduled to operate throughout the morning to allow for essential track maintenance. Passengers are advised to allow for at least 30 minutes of additional travel time and to check the latest digital display boards at stations for bus departure points. Normal train services are expected to resume by the early afternoon, though minor residual delays may occur.

Mount Ousley Interchange and M1 Updates

The M1 Princes Motorway remains a primary focus for commuters as work on the Mount Ousley Interchange project progresses. A permanent speed reduction to 60km/h is in effect near the base of Mount Ousley between Gaynor Avenue and the University Avenue overpass. While no full carriageway closures are scheduled for the daytime on Sunday, motorists should remain vigilant for heavy vehicle movements as crews continue earthworks and bridge abutment construction. Early morning drivers may encounter slight merging delays near the University Avenue off-ramp due to ongoing pavement stabilization work.

Local Roadworks and Suburban Delays

Wollongong City Council is currently overseeing several infrastructure upgrades that may impact local travel. Commuters should take note of the following active sites:

• Fairy Meadow: Significant road reconstruction continues on Dymock Street and Helen Brae Avenue. Traffic control is on-site, and resident-only access may be enforced during peak periods.
• Berkeley: Pavement improvements are underway on Salisbury Street. Motorists are encouraged to use alternative routes to avoid minor delays.
• Dapto: Ongoing works on Burke Road and near the West Dapto Road intersection continue to cause intermittent 'stop/slow' conditions.
• Keiraville: Resurfacing projects on Pooraka Avenue and Eastern Street may result in limited street parking and narrowed lanes.

Commuter Advice

Bulli Pass and Lawrence Hargrave Drive are currently open in both directions, providing a clear run for those traveling between the northern suburbs and the city. However, with the rail replacements in place, increased traffic volume is expected on the Princes Highway through Unanderra and Figtree. For the most accurate real-time updates, commuters are encouraged to monitor official transport apps before starting their journey.
