The Yamba Road and South Bank Road intersection upgrade is a major road reconstruction and flood resilience project designed to improve safety, traffic efficiency, and flood immunity along the key corridor between Maclean and Yamba. The project includes widening and raising the roadway, intersection upgrades, utility relocations, and active transport improvements.

In addition to flood mitigation, the upgrade improves safety through the construction of a channelised intersection, wider road shoulders, and enhanced line marking and signage for better visibility and guidance.

Project works consists of:

Reconstruction of approximately 900 metres of roadway
Raising the road by approximately one metre for improved flood immunity
Widening the road formation from eight metres to 12 metres Widening of the road corridor
Construction of widened road shoulders for cyclist accommodation
Upgrade of the South Bank Road intersection
Addition of a dedicated right-turn lane
Relocation of communications and electrical infrastructure
Replacement and relocation of ageing water main infrastructure
Future construction of cantilever cycle bridges adjacent to Palmers Channel bridge

Project Scope

Detailed civil and road design
Flood resilience and drainage design
Intersection design
Utility coordination and relocation design integration
Active transport and cyclist facility design
Design documentation and construction staging coordination
Stakeholder and authority coordination

Project Deliverables

Current

The Palmers Island bypass project is a major road infrastructure upgrade designed to improve traffic flow, road safety, and pedestrian amenity along Yamba Road. The project diverts through traffic away from the Palmers Island village and school zone while improving regional connectivity into Yamba.

The project works consist of:

Construction of a new one-kilometre bypass alignment
Channelised intersection upgrades at Palmers Island
Consolidation of local road access points
Shoulder widening and roadside safety improvements
Cyclist treatments and shared path infrastructure
Bus turnaround facilities
Flood resilience and drainage improvements
Land acquisition and corridor realignment works

Project Scope

Realignment of Yamba Road over approximately 1 km
Removal of multiple speed zone transitions to improve traffic progression
Consolidation of Yamba Street and School Road into a channelised seagull intersection
Bus turnaround facility with associated bus shelter
Shared path connection to improve pedestrian and cyclist access
Improved access arrangement for Palmers Island
Redirection of traffic movements away from Palmers Island Public School
Reduction in intersection conflict points and clearer turning movements

Project Deliverables

Detailed civil design for the road realignment and intersection upgrade
Horizontal and vertical road geometry design

[TESTIMONIALS]

WHAT OUR CLIENTS

HAVE TO SAY

I have worked closely with Pillar Rock on several complex road and drainage projects, and Shea consistently shows a strong level of technical expertise and professionalism. Pillar Rock produces high-quality design plans that are logical and well laid out, and Shea is a good communicator who is proactive in keeping her clients informed.

Pillar Rock enabled us to integrate our infrastructure designs with the end-client Civil Design package with ease. I find Pillar Rock responsive and intuitive to work with when we need additional design experience brought to bear on a problem.

Shea consistently demonstrated a high level of professionalism, dedication, and a strong work ethic. Her performance was of an exceptional standard, often exceeding expectations. One of Shea’s standout qualities is her proactive approach to problem-solving—she not only identiﬁed potential issues early but also presented well-considered, practical solutions for review. Her combination of technical expertise, initiative, and collaborative approach means I have no hesitation in recommending Shea for future project opportunities and we would welcome the opportunity to work with her again at AECOM.
