Engineering Survey for Highway Alignment in India -

Highway alignment refers to the positioning of a road in both horizontal and vertical planes. It includes the road’s path, curves, gradients, and elevation changes. A well-planned alignment minimizes construction and maintenance costs while ensuring safety and environmental sustainability.

Highway alignment is a crucial aspect of road construction that determines the best possible route for a highway, balancing safety, cost, and environmental considerations. An engineering survey plays a vital role in this process by providing accurate data on the terrain, soil conditions, water bodies, and existing infrastructure. A well-planned highway alignment ensures minimal land acquisition costs, reduced construction efforts, and long-term sustainability. According to the World Bank, every $1 billion invested in highways creates approximately 13,000 direct jobs, highlighting the economic significance of road development.
