Brassall Bikeway – Stage 4
Ipswich City Council (ICC) required a detailed design for the Brassall Bikeway Stage 4. The Brassall Bikeway forms part of ICC’s iGO Active Transport Action Plan and the Department of Transport and Main Roads (DTMR) Principal Cycle Network in Ipswich.

Our Project Mission
Our mission was to craft a high-quality and low-stress commuter cycle facility between Ipswich City Centre and the suburbs of Brassall. We implemented learnings gained from the Stage 2 of the Brassall Bikeway Project – which we also designed.
Our Approach
The project scope included a 3.5m wide shared path, 2.75km long, from the existing Brassall Bikeway at Grace Street northwards to Diamantina Boulevard in the suburbs of Brassall. The alignment followed the disused Brisbane Valley rail line, and the vertical alignment was optimised to build on the existing rail formation. The approach minimised excavation to reduce the risk of disturbance to the contaminated rail formation.
Three 25m long single-span steel bridges were designed at Iron Pot Creek and two waterways. Several bridge configurations were considered to optimise cost and the whole-of-life performance with considerations to the heritage context of the railway corridor. Geotechnical testing for the bridge abutments was undertaken, and considerations for waterway barrier works were applied. A Warren Truss bridge design was adopted, connecting the facility to the past rail heritage.
The project required two raised priority crossings to provide priority to cyclists to ensure directness, safety, and comfort. The civil works included hydraulic design, lighting design, landscaping, service relocations, and ensuring that the cycle path design and alignment met ICC and DTMR’s requirements.
The Result
We were proud to produce a design that adhered to and was consistent with the Safe System Approach and DTMR’s Active Transport Investment Program requirements, effectively controlling vehicle speeds to safeguard the public from crash forces that could result in fatal or serious injuries, ensuring a successful outcome for the project.
