Federal government pledges $100 million for extra lane on Great Western Highway

The Commonwealth announced a $100 million contribution to build an extra eastbound climbing lane on the Great Western Highway, complementing the New South Wales government’s repair budget for the partially closed road. The closure at Mount Victoria began in March after cracking was found in the 200-year-old Mitchell’s Causeway, forcing long diversions for commuters and freight. The additional lane will enable faster vehicles to pass heavy trucks climbing the steep section, improving traffic flow once the highway reopens.

Minister for Roads Jenny Aitchison confirmed the lane will not shift the target reopening window of the second quarter of 2027, while federal Transport Minister Catherine King stressed the corridor’s critical role for the Blue Mountains and Central West. Local MP Andrew Gee had earlier called for funding for a third lane, noting earlier design plans included it but no date or money had been set. Construction of the new road deck, supported by piles anchored to bedrock, is already underway with more than 150 workers on site.
