Major Weekend Road Closure for Mount Ousley Interchange Construction
Motorists in the Illawarra region are advised to plan ahead as a significant section of Mount Ousley Road will be completely closed throughout the upcoming weekend to allow for essential interchange upgrade works. The closure forms part of ongoing infrastructure improvements in the Wollongong area.
Specific Closure Details and Timing
The affected stretch of Mount Ousley Road runs between the Gaynor Avenue roundabout and the M1 Princes Motorway. Authorities have confirmed the closure will commence at 6:00 AM on Saturday and continue through until 4:00 AM on Monday, weather permitting. Should adverse weather conditions impact the scheduled works, the closure will be postponed to the following weekend.
While through traffic will be prohibited, local residents will maintain access along this section of road during the closure period. This measure ensures minimal disruption to those living in the immediate vicinity while allowing construction crews to work safely and efficiently.
Official Detour Routes and Expected Delays
During the closure, traffic will be redirected via established detour routes utilizing the Princes Highway, Memorial Drive, and University Avenue. Transport officials estimate these alternative routes will add approximately five minutes to typical travel times for most vehicles.
However, significant delays are anticipated for heavy vehicle operators. Due to low clearance at the University Avenue overpass, the southbound ramp will be temporarily widened to 4.5 metres to accommodate vehicles exceeding 4.6 metres in height. Northbound heavy vehicles over 4.9 metres high will face more substantial disruptions, requiring parking and escorted passage through the worksite when conditions allow, potentially resulting in delays of up to two hours.
Infrastructure Context and Regional Impact
This weekend closure represents a critical phase in the Mount Ousley interchange upgrade project, which aims to improve traffic flow and safety in this key transport corridor. The Illawarra region has experienced growing traffic volumes in recent years, making such infrastructure investments increasingly important for both commuters and freight operators.
Local authorities emphasize that while temporary inconveniences are unavoidable, the long-term benefits of the upgraded interchange will include improved traffic management, enhanced safety features, and better connectivity between local roads and the national highway network. Regular updates will be provided to ensure motorists remain informed about any changes to the schedule or traffic management arrangements.
