A $200 million reconstruction of the Great Western Highway at Victoria Pass is set to restore and strengthen a critical transport connection between the Blue Mountains and Central West, with upgrades designed to improve long-term freight movements and network resilience.
The Australian and NSW governments are jointly funding the project, each contributing $100 million towards rebuilding Mitchell’s Causeway and improving the highway for future traffic and freight demand.
The route has been closed since March 2026 after serious cracking and ground movement were detected at Mitchell’s Causeway, disrupting passenger and freight movements between the Blue Mountains and Central West.
Transport for NSW investigations identified deterioration within the historic causeway and informed the development of a permanent engineering solution for the crossing.
Building a more resilient crossing
Seymour Whyte was selected through an accelerated procurement process to deliver the new crossing at Mitchell’s Causeway.
Rather than relying on repairs to the existing structure, the project involves constructing a new road deck above the existing causeway, supported by piles anchored into stable bedrock below.
More than 150 workers have been inducted to deliver the project, with major reconstruction works underway.
The approach is intended to provide a more durable connection while restoring access along one of the key road links between Sydney, the Blue Mountains and communities and industries across the Central West.
Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King said restoring the connection remained a priority.
“This will not be a simple repair, but getting this done is a priority,” King said.
Additional capacity for freight movements
Beyond restoring the damaged crossing, the project will also deliver an additional eastbound climbing lane, permanently widening the highway through Victoria Pass.
The additional lane is intended to provide motorists with more opportunities to safely overtake trucks and other slower-moving vehicles.
For freight operators, the upgrade could help address delays caused by interactions between heavy vehicles and other traffic on the steep section of highway.
NSW Minister for Roads Jenny Aitchison said the government was using the reconstruction to address a long-standing issue along the route.
“By delivering an additional eastbound climbing lane, we are taking the opportunity to improve the road for the long term, allowing motorists to safely overtake slower-moving vehicles and trucks,” Aitchison said.
“This investment will address a long-standing pain point for locals and truckies, while ensuring we can get this vital road safely reopened as soon as possible.”
Closure highlights importance of freight connections
The prolonged closure has demonstrated the broader supply chain implications that can emerge when a critical regional transport corridor becomes unavailable.
Traffic has been diverted through alternative routes since the closure, increasing travel times and placing additional pressure on surrounding roads.
The disruption has extended beyond transport operators. Businesses across the Blue Mountains and Central West have reported impacts associated with freight movements, accessibility and longer journeys, highlighting the relationship between reliable road infrastructure and regional economic activity.
The NSW Government has introduced financial and other support for businesses affected by the closure while reconstruction continues.
Strengthening a regional supply chain link
The Great Western Highway provides an important connection for freight moving between Sydney and the Central West, supporting industries and communities that depend on reliable access to metropolitan and regional markets.
The rebuilt crossing is intended not only to restore that connection but also to improve its ability to accommodate freight and passenger movements over the longer term.
The additional climbing lane, more durable crossing and associated infrastructure improvements are expected to provide lasting benefits for freight operators, emergency services, local communities and businesses using the corridor.
The Great Western Highway at Victoria Pass is currently expected to reopen to traffic in the second quarter of 2027.
Once operational, the rebuilt section will provide a strengthened connection through the Blue Mountains and demonstrate the importance of maintaining resilient road infrastructure across Australia’s regional freight network.
