IRC 89 — Guidelines for Design and Construction of River Training and Control Works for Road Bridges (Second Revision)
IRC 89:2019 provides comprehensive guidelines for the design and construction of river training and control works specifically for road bridges. It addresses hydraulic and structural considerations to ensure stability and safety of bridge approaches against river flow, scour, and bank erosion. This standard is essential for civil and hydraulic engineers involved in planning, designing, and constructing river training structures such as guide bunds, spurs, and aprons to protect road bridges from hydraulic forces.
