Mt Ousley Carpark Closure and Nightly Lane Restrictions for Tuesday Commuters

Tuesday Commute Overview

Commuters across the Illawarra should prepare for continued disruptions today, Tuesday, 3 February 2026, as major construction milestones for the Mount Ousley Interchange project ramp up. While the morning peak is expected to flow relatively normally under standard construction-zone speed limits, specific closures and evening restrictions will significantly impact those utilizing the M1 Princes Motorway corridor and surrounding park-and-ride facilities.

Mount Ousley Interchange and Night Works

The primary focus for Wollongong motorists remains the Mount Ousley Interchange project. Transport for NSW has confirmed that nightly roadwork is scheduled from Monday to Thursday throughout February. For Tuesday evening, commuters should expect lane closures and traffic control measures to begin from 7:00 PM, lasting until 6:00 AM Wednesday morning. These works include extensive excavation and ground stabilization along Mount Ousley Road and the M1. Motorists are advised to allow extra travel time and adhere to the reduced speed limits that remain in place through the work zones during daylight hours to ensure the safety of on-site crews.

Commuter Carpark Closure

A critical alert for those who rely on the Mount Ousley Road commuter carpark: the facility is currently closed. The closure, which began yesterday, will remain in effect until 6:00 AM on Monday, 9 February. This total shutdown is necessary to allow for pavement upgrades and the construction of new intersection components. Commuters who typically park in this area are encouraged to seek alternative parking at nearby train stations or utilize local bus connections to reach the Wollongong CBD or the University of Wollongong.

M1 Princes Motorway and Heavy Vehicle Changes

Drivers on the M1 should remain vigilant for increased truck movements today. Soil and construction materials are being frequently transported between work sites on both sides of the motorway via University Avenue. Additionally, following the recent opening of the new heavy vehicle safety ramp, the old safety ramp remains closed. Heavy vehicle operators should ensure they are familiar with the new southbound configuration. Light vehicle drivers are reminded that significant traffic changes are occurring near the Northfields Avenue pedestrian bridge, which was recently upgraded to support the changing road alignment.

Public Transport and Bus Services

On the rails, the South Coast Line is currently operating on its standard weekday timetable with no major trackwork reported for the Tuesday daytime period. However, with the 2026 school year now in full swing, local bus commuters may notice minor adjustments to school-specific routes. Transport authorities recommend that students and regular bus users check their specific routes for any minor timing shifts intended to improve reliability across the network. Local commuters are reminded that V-Set trains have now been officially retired as of late January, so all services will be operated by the newer fleet.
