Enhanced sightlines and added channelised left/right turn lanes, extended turning lanes, and wide centreline treatments.
Over 3,800m³ of excavation, with disposal of unsuitable material and replacement using 2,700m³ of high-quality Class A1 fill (CBR-compliant).
Cuts and fills exceeding 5m, including trimming of narrow, constrained subgrades.
Rock protection placement in challenging terrain, coordinated to minimise disruption.
Pavement subgrade treatment using Type B methodology, employing high-quality Class 1A fill to address black soil and marginal materials.

Status
Completed (Jan 2024 - Dec 2024)
The project involved the construction of the 16.3 km Lismore to Bentley section of the Northern Rivers Rail Trail. The scope included earthworks, vegetation clearing, rail infrastructure modifications, and the construction of pathways, bridges, and facilities to create a multi-use trail catering to pedestrians, cyclists, and equestrian users. Significant community, cultural, and historical inputs were incorporated into the project.
Scope of works:
Establishment of the rail corridor and fencing alignment by a qualified surveyor.
Clearing and vegetation management within the corridor while preserving mature trees, unless approved.
Repairing embankments and addressing erosion.
Constructing the rail trail pathway, bridle trail, and associated drainage (culverts, swales, and table drains).
Restoring and repairing 20 bridges, some up to 77 metres long, while salvaging reusable materials such as historic bridge timbers.
Installing bypasses for bridges and safety measures at road and stock crossings.
Constructing five rest areas with shelters, picnic tables, bike racks, hitching rails, and water troughs.
Installing gates, fencing, and bridle enclosures.
Seeding disturbed areas, turfing around rest areas, and removing temporary works (e.g., fencing, sediment controls).
Key Features:
Hazell Bros engaged local suppliers to create features such as a "Lismore" sign, a 4m bike rack, and horse-hitching rails using repurposed railway steel and historic bridge timbers.
External works were completed at the heritage-listed Lismore Railway Station precinct.
Collaboration with historical, Aboriginal, and community groups informed interpretive signage that celebrates the area's cultural and historical significance, including contributions from the Ngulingah Local Aboriginal Land Council.

Status
Completed
The Hobart Airport Interchange project was required to replace the existing Hobart Airport roundabout with a solution that improved the existing traffic congestion and allowed for high projected growth for the Hobart Airport and the Sorell/Cambridge area.
After an initial design phase, the Department of State Growth elected to undertake the project as design and construct contract model to allow for innovative solutions from the industry. During the tender phase, Hazell Bros partnered with designer Cardno and proposed raising the Tasman Highway over the intersection, a design solution focused on the following key items:
Providing a high level of service in accordance with 2041 traffic modelling.
Minimising traffic impacts to the road user during construction through carefully designed temporary traffic arrangements and staging.
Delivering a value for money outcome for the Department of State Growth.
The final design of the interchange was comprised of the following key items:
A 22-metre wide, 44-metre long dual span overpass bridge structure, overpass for the Tasman highway founded on driven piles.
100,000m³ on imported and placed embankment material to construct the two bridge approaches of the Tasman Highway.
Construction of four on/off ramps on existing ground level
A “dog bone” roundabout connecting on/off ramps, Kennedy Drive and Holman Avenue below the overpass.
Extension of the 4-lane arrangement east, past the Hobart airport runway
Extensive service relocations, including TasWater, TasNetworks, Telstra, NBN and Optus.
Installation of a new lighting network to all ramps and intersections
Installation of a new ITS system including smart cameras, and two overhead gantry VMS information boards.
Installation of a detailed stormwater network on low lying ground including settlement ponds to account for high flow situations
Upgrades to local roads to improve access safety to local businesses and the Hobart Airport

Signalising the Eatons Crossing Road and Lilley Road intersection, Warner.
Widening Strathpine-Samford Road just west of Queen Elizabeth Drive to Gibbons Road.
Installing a wide centre line treatment to provide additional separation between vehicles travelling in opposite directions.
Shoulder widening to provide additional trafficable area to pull over, assist emergency vehicles to pass, accommodate wide vehicles and greater separation between cars and bike riders.
Providing safety barriers at various locations and removing roadside hazards (including necessary vegetation clearing).
Modifications at several intersections including dedicated right-turn lanes at Dawneta Court, Albion Road, Lascelle Court, Boland Court, Hodge Road, Lergessner Road, Lawson Road, Alpine Drive and Gibbons Road.
