Mt Ousley Interchange Night Works and UOW Peak Diversions Impact Wednesday Commute

Wollongong Traffic and Commute Update: Wednesday, 18 March 2026

Commuters across the Illawarra should prepare for a mix of morning peak diversions and evening construction activity today, Wednesday, 18 March 2026. While the M1 Princes Motorway remains open in both directions during daylight hours, significant infrastructure projects and local maintenance schedules will necessitate extra travel time, particularly around the University of Wollongong (UOW) and several southern suburbs.

Major Arteries and Mt Ousley Interchange

Work on the Mt Ousley Interchange project continues to be the primary focus for regional traffic management. Motorists are advised that standard night work is scheduled to take place tonight from 7:00 PM until 6:00 AM tomorrow. While a full motorway closure is not scheduled for this evening, road users should expect lane closures, reduced speed limits of 60km/h, and increased heavy vehicle movements as crews focus on vegetation mulching and utility installations near the base of the mountain.

Additionally, the Wollongong Education Precinct temporary traffic changes remain in effect. Between 7:45 AM and 9:15 AM this morning, southbound traffic exiting the M1 at University Avenue will be diverted left to perform a U-turn at the eastern roundabout. This measure is designed to manage high volumes of student and staff arrivals. Drivers heading to Keiraville or Gwynneville are encouraged to use the Robsons Road entry at West Wollongong to avoid congestion near the campus gates.

Local Roadworks and Suburban Delays

Wollongong City Council has a busy maintenance schedule for mid-week. Commuters should watch for "stop/slow" traffic control at the following locations:

• Dapto & Kembla Grange: Ongoing road reconstruction is active on Burke Road, West Dapto Road, and Wyllie Road. Delays are expected near the newer urban release areas.
• Fairy Meadow: Pavement improvements continue on Dymock Street and Helen Brae Avenue.
• Berkeley: Maintenance crews are working on Salisbury Street.
• Northern Suburbs: Roadworks are scheduled for Cater Street in Coledale and Railway Avenue in Austinmer.
• Central Wollongong: Footpath upgrades are impacting pedestrian flow on Bank Street and Rosemont Street.

Public Transport and Special Events

The South Coast Line is operating on a standard weekday timetable today with no major trackwork disruptions reported for the Wollongong area. However, fans heading to Sydney for the AFC Women’s Asian Cup Semi-Final this evening are urged to plan ahead. While the match is being held at Olympic Park, increased patronage is expected on Northbound services throughout the afternoon. Standard Opal fares apply, and commuters should check for any late-notice service adjustments via official transport apps.

Commuter Advice

Motorists are encouraged to allow an additional 10 to 15 minutes for trips involving the M1/University Avenue interchange during the morning peak. For those traveling after 7:00 PM, stay alert for flashing lights and worker proximity on Mt Ousley Road. Weather conditions are expected to remain stable, but always drive to the local conditions and follow the instructions of on-site traffic controllers.
