Ayrshire Roads Alliance, Sweco, and Story Contracting collaborated to design and construct a new dedicated pedestrian and cyclist underpass linked to the strategic National Cycle Network, eliminating the need to cross the A719 carriageway. The previous setup was an uncontrolled crossing of a 60mph single-carriageway road, with poor visibility of southbound vehicles and a history of fatal and serious road injury collisions. The construction of the new underpass has opened up the potential of an existing local walking and cycling path from Alloway to Doonfoot, creating a completely traffic-free route. To enhance the community’s benefit, a sensory garden and biodiversity area were established from an underutilised piece of land, providing an environment enjoyable for all.
The community was deeply involved in the project, with Ayrshire Roads Alliance adapting the Burton Underpass and Sensory Garden scheme through engagement with local walking and cycling groups, addressing key barriers to increased active travel use in the area. Sweco was commissioned to develop the design proposals. In a collaborative effort among the client, designer, and contractor, the team took the scheme from inception to construction. A high-quality 3D visualisation was produced, allowing for a video fly-through of the proposals to be created and distributed using an online StoryMap. This innovative approach facilitated clear communication of the designs to key stakeholders, resulting in a greater understanding and buy-in from the local community.
Story Contracting was responsible for bringing the design to life. The project team ensured that sustainable and locally sourced materials were used throughout the construction phase. The new underpass location was once part of a historic railway route (The Maidens and Dunure Light Railway), which was considered in the design and construction. Sustainable materials such as railway buffers and old railway sleepers were used for planters and cycle parking, along with coping stones uncovered during construction from the wingwalls of the old railway crossing structure, which were used as rock features. The sensory area includes a wetland area, pathways, a boardwalk with a sensory route, and planting that stimulates visitors’ senses through touch, sight, scent, taste, and hearing. The local primary school was involved throughout the design and build process, including STEM sessions, site visits, a naming competition, planting, and the official opening ceremony of the underpass and sensory garden.
