Brief description
Located in the north-eastern quadrant of the interchange between the A4 motorway and the regional road SR 89 Treviso Mare, the Meolo Junction functions as a strategic node within the national motorway network, connecting long-distance traffic flows with the Adriatic coastal system. The interchange supports regional mobility while accommodating significant seasonal tourist demand.
The project includes the construction of a trumpet-type, grade-separated interchange; a three-span motorway overpass built with full-section steel girders; a toll plaza with nine exit lanes, four entry lanes, and two lanes dedicated to oversize and special transport; a roundabout system integrating the interchange with SR 89; the station forecourt and related urban interfaces; a 13,000-sqm surface park-and-ride facility; and a constructed wetland for runoff management with a capacity of 9,500 cubic metres. Landscape engineering works comprise earth modelling, hydro-morphological restoration, and ecological planting.
Beyond its technical function, the intervention was conceived as a territorial gateway, capable of establishing a new landscape interface between infrastructure, environment, and surrounding settlements. The design framework integrates environmental engineering and transport infrastructure to address acoustic and visual mitigation, water cycle management, and spatial coordination with existing utilities and transport corridors.
Landscape design plays a structuring role, ensuring ecological continuity and visual integration across the site. The system includes more than 7,300 metres of open-air channels and drainage ditches, together with the planting of approximately 7,000 specimens selected in accordance with local ecological conditions. Sculpted berms and native vegetation contribute to noise attenuation, visual filtering, and long-term landscape coherence.
With a total investment of €34.8 million, the project was delivered one year ahead of schedule, achieving significant optimisation in construction time, cost control, and resource management, while establishing a durable landscape framework for a highly complex infrastructural environment.
