This project involves the upgrading of road intersections and sections along Booyal Dallarnil Road, Paradise Dam Road, and nearby locations to meet the operational and safety standards required for the main Paradise Dam Improvement Project. The upgrades will include major intersection improvements and associated roadworks, such as pavement reconstruction and drainage enhancements. The works will take place across remote sites, requiring effective traffic management plans due to high-speed rural traffic. The project aims to improve the functionality and safety of key road connections, with works primarily focused on intersection upgrades and road realignments.
Scope of Works:
Realignment and pavement reconstruction
Embankment widening
Improvements to property access
Signage and linemarking works
Drainage works and drainage structures
Intersection improvements, including three major intersections:
Booyal Dallarnil Road and Bruce Highway
Booyal Dallarnil Road and Paradise Dam Road

The Pearces Creek Bridge Replacement project involved replacing the existing four-span timber bridge on Eltham Road over Pearces Creek, located on the boundary of Lismore City and Ballina Shire LGAs. The new reinforced concrete bridge, built on the downstream side of the existing structure, was designed to support two-lane traffic and meet a 100-year design life. The project incorporated the installation of new substructures and superstructures via dual crane lifts and included the demolition of the original timber bridge.
Scope of Works:
Bridge Construction and Demolition:
Implementation of staged long-term traffic guidance schemes with traffic control.
Piling and construction of reinforced concrete abutments.
Installation of five 32m Super T Girders using dual crane lifts.
Demolition and removal of the existing timber structure.
Earthworks and Pavements:
20,000 m³ of cut/fill earthworks with complex rock subgrade treatments.
Construction of 6 m high embankments approaching the bridge structure.
Flexible pavement construction (800 m), completed adjacent to a live roadway under a traffic guidance scheme.
Environmental and Miscellaneous Works:
Fauna protection, material stockpiling, and riverine environmental management.
Installation of cross drainage structures, concrete batter chutes, and vegetation clearing.
Topsoil placement, landscaping, and wearing course installation.
Line marking, signage, and other road furniture.
Project Highlights:
Constrained Site and Innovative Solutions:
Piling and crane pad design enabled safe delivery within tight site constraints.
Temporary weir river crossing, approved by NSW Fisheries, provided access to both abutments for heavy equipment, reducing interaction with local road users.
Girder Delivery Challenges:
Managed complex logistics for delivering 32 m girders on rural roads, addressing bridge load limits, low-height bridges, and horizontal curve alignments.
Traffic Management:
Conducted three traffic switches of the existing roadway.
Implemented a full road closure detour for critical works, contributing to early project completion.
Utilities Coordination:
Liaison with Essential Energy to temporarily lower overhead powerlines for piling and girder installation. Power was maintained for stakeholders using generators during critical works.

Hazell Bros is working on the Strathpine-Samford Road Route Safety Project, locally known as Eatons Crossing Road and Mount Samson Road. This key road connects Eatons Hill and Samford. The project aims to improve safety and efficiency along the Strathpine-Samford Road corridor. Key elements include signalising major intersections, widening specific road sections, and installing a wide centre line treatment to enhance vehicle separation.
The detailed scope of works includes, but not limited to:
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.
Installing a dedicated left-turn lane at Clear Mountain Road, Hodge Road, Lergessner Road, Alpine Drive and Gibbons Road to separate turning vehicles from through-traffic lanes.
Improved bike rider safety with 2m wide shoulders marked with bike symbols and intersection conflict points marked with green paint and bike symbols.
Provision of new police enforcement bays at identified locations.
