Regional mayors and community leaders are intensifying calls for financial assistance as the closure of the Great Western Highway enters its 100th day, creating ongoing disruption across western New South Wales.

The highway was shut in March after significant structural concerns were discovered at the historic Mitchell's Causeway near Victoria Pass. Since then, thousands of motorists, freight operators, tourists, and local residents have been forced to use lengthy alternative routes, increasing travel times and costs.

Local councils say the extended closure has placed enormous pressure on businesses that rely on tourism and through-traffic. Many operators have reported major declines in customer numbers, while freight and transport costs have risen substantially due to detours and delays. Community leaders warn some businesses could struggle to survive if additional support is not provided.

Mayors from affected regions argue that the economic impact now extends far beyond the immediate closure zone, affecting communities throughout the Blue Mountains, Lithgow, Bathurst and the broader Central West. They are seeking greater state and federal assistance, including expanded business grants, tourism recovery funding, and support for transport services.

Healthcare providers and community transport groups have also raised concerns. Longer travel routes are making it more difficult for patients from regional areas to reach specialist medical appointments in Sydney, while transport providers face increased operating expenses.

The NSW Government previously announced a $3.5 million support package, including grants for eligible small businesses and funding for tourism initiatives. However, local representatives argue the assistance does not fully reflect the scale of losses experienced across the wider region.

Repair plans continue to be assessed, with authorities balancing the need for urgent infrastructure work against heritage requirements associated with the nearly 200-year-old structure. Government officials have stated that reopening the highway remains a priority, but a definitive completion date has yet to be announced.

As winter conditions approach, regional leaders are warning that delays could further affect road safety, tourism activity, freight movement, and economic confidence throughout western New South Wales. Calls are growing for accelerated repairs and additional funding measures to support communities until the highway is fully reopened.
