The Narmada Expressway project in Madhya Pradesh is one of India's longest highways, spanning eight lanes across diverse landscapes. Confronted with challenges like undulating terrain, river crossings, and urban passages, the project demanded innovative solutions. Leveraging advanced geospatial technologies from Bentley Systems, including OpenRoads Designer, OpenBridge, and STAAD Pro, the project team tackled these challenges head-on. Through 3D modeling, analysis, and design optimization, they achieved efficient alignment planning and geometry optimization, ensuring adaptability to complex environmental factors in real-time. This approach prioritized sustainability, cost-effectiveness, and safety, setting a new benchmark for transportation infrastructure development in the region and beyond.
