Delivered in two stages by Alder for Redland City Council, the project links Snapper Street lookouts over Frenchman’s Beach with the Gorge Walk Trailhead, creating a seamless coastal pathway through one of Queensland’s most scenic destinations.
Stage 1, completed in late 2021, involved the installation of timber boardwalks and viewing decks using Wagners CFT substructure and Modwood decking, alongside decorative concrete surfacing and coloured bitumen footpaths. Works included road construction with kerb and channel, stormwater infrastructure, and land remediation. Park furniture, fencing, bike racks, and waste enclosures were installed, complemented by landscaping with rock retaining walls, erosion control matting, and native planting. Community engagement and careful staging ensured minimal disruption during peak holiday periods, with local subcontractors and Indigenous workforce participation.
Stage 2 extended the trail from Snapper Street to the Gorge Walk Trailhead, incorporating 900m² of composite boardwalk and the Frenchman Stairs upgrade—220 steps spanning a 40-metre vertical rise. Additional works included 477m² of Streetflex coloured bitumen paths, custom park furniture, and 4,500m² of landscaping with mulching, jute matting, and revegetation. Structural elements comprised 130 screw piles and 130 driven composite piles with concrete pilecaps. Alder navigated challenging terrain and remote site logistics while engaging local North Stradbroke Island businesses for civil works and landscaping.
Together, these stages showcase Alder’s expertise in delivering complex infrastructure in environmentally sensitive and high-profile locations, balancing functionality, durability, and community benefit.
