Overview
- NSW authorities say the shutdown will run for a minimum of three months, with Minister Jenny Aitchison calling it “not a short-term repair job” and announcing extra trains, buses and coaches for affected communities.
- Geotechnical teams will spend about a fortnight diagnosing the cause, including drilling into the 1830s causeway and installing instruments to track pore water pressure and ongoing movement to guide the repair plan.
- Traffic is being diverted through Lithgow via the Bells Line of Road and Darling Causeway, with a tow truck stationed for struggling heavy vehicles and typical trips extended by about 25 minutes, with longer delays on weekends and holidays.
- Local residents and businesses report severe disruption, with Lithgow streets jammed and roadside traders such as The Lolly Bug seeing customer numbers collapse as highway traffic vanishes.
- The route carries roughly 12,000 vehicles a day and a large share of over‑mountain freight, including about 900,000 tonnes of food each year, raising concerns over delivery times, costs and truck safety on the alternative route.
