M1 Motorway Extension to Raymond Terrace: Black Hill to Tomago Works

Gamuda Australia was awarded a major road transport project by the NSW Government to deliver the Black Hill to Tomago Package of works for the M1 Motorway Extension to Raymond Terrace.

The design and construct contract will be delivered through a 60-40 joint venture with John Holland.

The scope of works includes:

• 10km greenfield dual carriageway motorway link between the M1 Motorway at Beresfield and Tomago
• major interchanges at Black Hill, Tarro and Tomago
• construction of nine bridges including a Viaduct approximately 2.6km-long across the Hunter River and floodplain.

The is our third infrastructure project in Australia and one of the largest in the Hunter region's history. It’s a game changer for local, regional and long-distance transport, unlocking congested Hunter roads and helping complete a traffic-light-free highway between Sydney and Brisbane.

Currently, the existing M1 Motorway, New England Highway and Pacific Highway carry some of the highest traffic volumes across the Hunter region, with an estimated 50,000 motorists using the corridor daily.

When completed, the M1 Motorway extension will bypass the congestion and merge points along this corridor and reduce traffic volumes across the existing network.

Planning and detailed design works will commence immediately with site investigations and utilities work in mid 2023, with final project completion in mid 2028.
