IRC:73 Explained | Lane Width, Superelevation & Curve Design Standards for Indian Highways

Have you ever wondered why Indian highways have standard lane widths, gentle curves, or smooth gradients? It's not random – it's based on **IRC:73–1980**, the official geometric design standard for rural highways in India. In this video, we go deep: ✅ Why IRC:73 exists and why it matters ✅ Science behind 3.5 m lane width & driver psychology ✅ How curves are designed using superelevation & minimum curve radius ✅ Importance of sight distance (SSD) & safe stopping ✅ Gradient rules & real-world design process for DPR consultants We even share a practical example of designing a highway stretch in Madhya Pradesh. Perfect for: Civil engineering students & job aspirants (GATE / SSC JE) Junior engineers & DPR/PMC consultants Anyone curious about how Indian roads are actually designed 📌 Watch till the end to see why these standards keep drivers safe and traffic flowing smoothly. 👉 Subscribe to *InfraYatra* for more videos on IRC codes, DPR process, cost estimates & real project case studies. #IRC73 #CivilEngineering #HighwayDesign #InfraYatra #GeometricDesign #RoadSafety #DPR
