Bridge Design & Documentation

Creating safer, seamless active-transport connections through elegant long-span bridge engineering.
This project involved the design and documentation of two new long-span steel truss pedestrian and cyclist bridges that complete a vital active-transport link across major arterial roads.
The bridges—each featuring wide shared-path decks, architecturally integrated safety screens, and illuminated signage—were engineered to provide safe, accessible crossings while integrating sensitively with adjacent residential and road environments. CSS delivered the full detailed design for both structures, ensuring the bridges met demanding functional, architectural, and spatial constraints within a tightly bounded urban footprint.
Technical Achievements
CSS engineered two complex through-truss superstructures with curved bottom chords to optimise clearance envelopes and minimise approach ramp lengths—an innovative geometry that significantly reduced structural bulk and foundation impact. The team also integrated perforated metal mesh screens that served dual purposes: providing safety protection and delivering tailored privacy outcomes for adjoining properties. The trusses were designed to support large illuminated LED signage boards, requiring careful consideration of dynamic loading, serviceability and structural integration. The result was a technically robust and architecturally cohesive pair of bridges with refined detailing across steelwork, concrete approaches, and urban interface requirements.
Benefits to the Client
By minimising pier heights and reducing ramp lengths, CSS’s design enabled the bridges to fit within the available land footprint while meeting all accessibility and gradient compliance standards. The combined safety–privacy screen solution reduced visual impact and eliminated the need for additional structures, optimising cost and maintenance outcomes. The design successfully balanced aesthetics, functionality, constructability and long-term durability, delivering a safe and attractive piece of active-transport infrastructure that enhances connectivity across the precinct.
