The Great Western Highway's Victoria Pass section will remain closed until at least April to June 2025, forcing Blue Mountains and Central Tablelands residents to endure extended travel times and detours. Transport for NSW shut the road in March after critical structural cracks were detected at Mitchells Causeway, a 194-year-old convict-built bridge.
New Bridge Construction Planned
The NSW government announced on Friday that a new structure will be built above the existing causeway, with construction starting within weeks. The bridge, used by about 12,000 vehicles daily, will be stabilised as part of the work. The new crossing could allow for an additional lane in the future, something not possible with the current bridge.
Civil engineering contractor Seymour Whyte was selected following an accelerated procurement process that drew 10 submissions. The government also announced an additional $20m in financial support, increasing grants for small businesses in hardship from $10,000 to $25,000 and expanding eligible areas.
Community and Political Reaction
NSW Liberals leader Kellie Sloane said there is “white-hot anger” among cut-off communities, calling the compensation package inadequate. “Businesses simply cannot survive another 10 plus months without meaningful support,” she said. Nationals MP Paul Toole expressed doubt about the completion date, noting over 100 critical comments on social media. He urged around-the-clock work to expedite the project.
Blue Mountains MP Trish Doyle defended the project: “We’re not just fixing what was there for the short term, we’re building something better. A new structure, properly engineered and anchored into solid bedrock, built to last.”
Engineering Perspectives
Behzad Fatahi, professor of civil engineering at University of Technology Sydney, called the plan a “practical way forward” given the steep, narrow terrain. He explained that adding a lane now would require a wider deck and more piles, adding cost and risk. Maria Rashidi from Western Sydney University described the strategy as “technically sound” and said the reopening target is achievable barring unforeseen ground conditions or weather delays.
The Nepean Blue Mountains Local Health District confirmed the updated timeline would not compromise local healthcare. The government will also provide free coaches and spend $50m on detour route upgrades.
