Overnight Tunnel Closures and Camden Show Events to Shape Thursday Commute

Overnight Artery Closures Impacting Early Commuters

Commuters heading into the city early this morning, Thursday, 19 March 2026, should be aware of several major road closures that may affect travel times. The Sydney Harbour Tunnel is scheduled for a full northbound closure until 5:00 AM. Motorists traveling toward the North Shore during the pre-dawn hours are advised to detour via the Sydney Harbour Bridge. A similar closure is planned for late tonight, starting at 10:30 PM, which will again restrict northbound access until Friday morning.

Significant maintenance is also taking place on the Westlink M7. Overnight works have necessitated the closure of northbound lanes between Richmond Road in Oakhurst and Woodstock Avenue in Rooty Hill. Additionally, southbound lane closures have been in effect between the Great Western Highway and Old Wallgrove Road in Eastern Creek. These sections are expected to reopen by 4:30 AM, but residual delays may occur as heavy vehicle traffic resumes its normal patterns through these key Western Sydney corridors.

Major Events and Local Road Disruptions

The annual Camden Show officially begins today, bringing significant changes to local traffic in the Macarthur region. John Street is closed to all vehicle traffic between Mitchell Street and Exeter Street. These closures will remain in place through Saturday. Motorists in the Camden area should expect increased pedestrian activity and are encouraged to use Argyle Street as an alternative route, though heavy congestion is anticipated during the morning and afternoon peaks.

In Sydney Olympic Park, the final road closures following the AFC Women’s Asian Cup Semi-Final are expected to be cleared by 3:00 AM. Streets including Dawn Fraser Avenue and Olympic Boulevard, which were restricted for pedestrian safety during the event, will return to normal operation for the morning peak. However, commuters should remain alert for lingering event infrastructure and temporary fencing as pack-down operations continue throughout the day.

Public Transport and Rail Outlook

Sydney’s rail network is largely operating on a standard weekday timetable today, with no major daytime trackwork reported for the T1 North Shore or T4 Eastern Suburbs lines. However, bus commuters in the Olympic Park precinct should note that routes 525, 526, and 533 may still experience minor diversions in the early hours of the morning until all barricades are removed following last night’s match.

Commuter Strategy for Thursday

While the major arterial closures are timed to conclude before the heart of the morning rush, the volume of traffic on the M4 and M5 motorways is expected to be high. Drivers are encouraged to allow an additional 10 to 15 minutes of travel time if passing through Eastern Creek or Oakhurst. For those heading to the Camden Show, public transport remains the most reliable option to avoid local parking constraints and road closures around the showgrounds.
