Guidelines for Design and Construction of River Training and Control Works for Road Bridges (First Revision)
IRC 89 (1997) provides comprehensive guidelines for the design and construction of river training and control works specifically for road bridges in India. It addresses critical hydraulic and structural considerations such as guide bunds, spurs, floor protection, and approach embankment protection to ensure stability and longevity of bridges over rivers, including major alluvial and sub-montane rivers. This standard is essential for engineers involved in the planning, design, and construction of river bridge infrastructure to mitigate scour, control river flow, and protect bridge foundations against hydraulic forces and sediment transport.
