Construction progress

The southern section of the project (Black Hill to Tomago) hit another milestone with the installation of girders at the Tomago interchange, opposite Old Punt Road.  

The girders span 50 metres and, due to their size and weight, were cast and delivered in two halves for easier handling and transportation. These halves will be joined and stressed together on site.  

The southernmost of the eight bridges on the project – near the corner of Pacific Highway and John Renshaw Drive - has also progressed well in the period with girder installation commenced. 

The team has made significant progress on numerous fronts during October including:   

• construction of the temporary rock platform in the Hunter River continued with installation of pile liners 

• work on the 2.6-kilometre viaduct (bridge) continued with column, headstock and girder placement gaining momentum 

• continuation of bridge work for Black Hill, Old Punt Road, Tomago and Tarro interchanges 

• good progress on noise wall, pavement and drainage works on Lenaghans Drive and M1 in preparation of a traffic switch for Lenaghans Drive in December 

• continuation of utility relocation works including communication infrastructure for Telstra, Optus, Vocus and Jemena medium and high-pressure gas main works 

• stage 1 bulk earthworks is substantially complete with road pavement materials ramping up 

• minor surfacing work on the existing road network continuing. This will increase in the coming months as the project starts to tie into the existing road network. 

This month, we reached a major milestone at the Raymond Terrace interchange with the successful placement of the first eight girders on the project.

Our team has also been hard at work at Windeyers Creek, where we’ve completed the installation of steel piles and poured concrete for key structural elements, preparing the area for the next stage with 54 more girders set to arrive on the project soon.

At Masonite Road, we're making strong headway on earthworks as we prepare for the final phase of piling for bridges, which will support the new bridge structure over the road, keeping us on track for upcoming stages.

Across the project, foundation treatments and bulk earthworks are 75% complete. Alongside these advancements, topsoiling and planting have commenced along completed drainage areas.

To protect the Tomago Sand Beds, we're constructing a series of water quality basins designed to capture any potential spills from the motorway before they reach sensitive areas. Over the past months, we've installed liners in these basins and poured over 800 cubic metres of concrete to secure them.

The southern section of the project (Black Hill to Tomago) hit another major milestone with the first bridge deck being poured in mid-September.

The new bridge, located opposite Tomago Road, will form part of the new motorway interchange at Tomago.

We have made significant progress on numerous fronts during September including:  

• work began on the temporary rock platform in the Hunter River for construction of viaduct (bridge)

• work on the 2.6-kilometre viaduct (bridge) continues with piling now on the northern side of the Hunter River

• continuation of bridge work for Black Hill, Old Punt Road, Tomago and Tarro interchanges

• continuation of utility relocation works including communication infrastructure for Telstra, Optus, Vocus and Jemena medium and high-pressure gas main works

• completion of temporary carriageway alignment on Pacific Hwy and Tomago Road to prepare for the upcoming traffic switch

• traffic signal work at Tomago Road / Pacific Hwy

• noise wall, pavement and drainage work on Lenaghans Drive and M1

• moved more than 1.6 million tonnes of material from cut to fill area ahead of paving

• commissioning and testing for the pug mill for paving. 

Despite the wet weather during the middle and end of September, significant progress was made in drainage work, with the completion of open drains at the southern end of the project in Heatherbrae. This included the excavation and installation of the waterproof membrane for permanent basins which we are expecting to commence concrete pouring next month.

Foundation treatments have been completed at the northern end of the project, while bulk earthworks continue across the project forming the new motorway alignment.

Bridge construction also saw some key milestones, with piles for bridge abutments at Windeyers Creek (Bridge 11) completed and the central pier for the bridge at the Raymond Terrace Interchange (Bridge 12) successfully poured.

We're looking forward to the next month as we continue to fabricate the girders (concrete beams) for Bridge 12, which will be lifted and placed into position to form the new carriageway.

Watch this space!

The southern section of the project (Black Hill to Tomago) hit a major milestone with the first bridge girders lifted into place in early August. This marks a crucial step in the construction of the 2.6km viaduct (bridge) spanning the Hunter River, the Main North Rail Line and New England Highway.   

We have made significant progress on numerous fronts during August including:  

• successful relocation of the Hunter water main which will enable the team to complete work next to the New England Highway  

• moving about one million tonnes of earth from cut areas to fill areas  

• start of landscaping batters to stabilise and manage dust 

• temporary pavement widening on the Pacific Highway, New England Highway and M1 Motorway to prepare for future traffic switches 

• utility relocation for Optus, Telstra and Vocus at Tarro and the Pacific Highway 

• start of bridge work for the new interchanges at Black Hill, Tarro and Tomago 

• work on the 2.6-kilometre viaduct (bridge) including construction of columns and headstocks ahead of placement of girders 

• preparation for paving with the establishment of a pug mill on site. 

In August, we continued bridge construction at the northern end of the project, including driving pile cases and a pouring concrete at the new interchange at Raymond Terrace site (Bridge 12) and Windeyers Creek (Bridge 11).

Other activities carried out during the month included:

• placing and compacting imported fill material

• installation of cross drainage culverts and headwalls

• foundation treatments

The project team has been busy with bulk earthworks and drainage either side of the Hunter River and pavement work is now underway on the existing M1 Motorway and Lenaghans Drive ahead of upcoming traffic switches.

Piling for the viaduct is also continuing on the western side of the Hunter River and the team is preparing for its first girder lift in early August.

Other key work activities included:

• Piling for interchange bridges for the New England Highway and M1 Pacific Motorway

• Reinforced wall construction near Tomago Road and Old Punt Road

• Concrete work for the bridge near Tomago Road

• Preparation for the relocation of the Hunter Water main

During July, the Heatherbrae Bypass team began piling activities at the northern-end of the project at Raymond Terrace. These works include the mobilisation of a 300-tonne crane and piling rig at the new interchange at Raymond Terraces site (Bridge 12) and a 110-tonne crane at the new main carriageway over wetlands at Windeyers Creek site (Bridge 11) which will be used to drive steel tube piles into the ground.

Other activities carried out during July included:

• placing and compacting imported fill material

• installation of cross drainage culverts and headwalls

Bulk earthworks and drainage continued in June both north and south of the Hunter River. Pavement works on the existing M1 Motorway and Lenaghan Drive also continued along with piling for the viaduct. Piling equipment was moved to two other bridge locations and the first bridge headstock was poured for the viaduct.
