The Singleton Bypass is on track to open to traffic later this year, with construction teams back from the break and hard at work, delivering an extraordinary project for the Hunter.

The project is being delivered with a $560 million investment from the Albanese Labor Government and a $140 million investment from the Minns Labor Government.

This region-changing project will take 15,000 vehicles a day off Singleton’s main street, improving travel times, freight efficiency and safety for local and interstate motorists, allowing them to avoid five sets of traffic lights.

The eight kilometre bypass starts near Newington Lane in the south and rejoins the highway just past Magpie Street in the North. The project features a full interchange at Putty Road and connections to the New England Highway at the Southern and Northern ends and at Gowrie.

A host of major milestones were achieved in 2025, with crews opening two bridges which allowed trucks to shift material within the project corridor, without going through the CBD, helping to reduce the impact of construction traffic.

Construction of all six bridges is now nearing completion, including the largest on the Hunter Floodplain, which is 1.6km long. 

The bridge construction has involved the installation of 435 girders and 207 bridge piles and pouring of 161 concrete columns and 78 concrete bridge decks. Only the finishing works remain, including the installation of safety rails, deck joints, placement of asphalt, noise walls and safety screens.

Road pavement construction has recently commenced across the corridor.

To date, a total of 500,000m³ of earthwork material has been placed across the project alignment, equivalent to 200 Olympic sized swimming pools of material.

Construction activities continuing in early 2026 include:

• drainage and earth works
• continued pavement construction including asphalting and line marking
• the relocation and connection of water, electrical and sewer services
• the construction of interchanges, and
• the start of landscaping.

The bypass is expected to be open to traffic in late 2026, weather permitting.
