The design of a highway bridge is critically dependent on standards and criteria. Naturally, the importance of highway bridges in modern transportation system would imply a set of rigorous design specifications to ensure the safety, quality and overall cost of the project. Bridge design practices differ very extensively throughout the world. Many codes are currently dealing with limit state method; IRC 112:2011 combines specifications for both RCC and pre-stressed concrete bridges. It introduces durability of concrete, general dealing requirement of different bridge members, grade of concrete is allowed up to M90 and grade of steel used up to Fe 600. In the present work, an attempt will be made to compare between IRC 21:2000 “Standard Specification and Code of Practice for Road Bridges
Section III, Cement Concrete (plain and reinforced)” and IRC 18:2000 “The Design Criteria for Pre-Stressed Concrete Road Bridges (Post-Tensioned Concrete)” with IRC 112:2011 “Code of Practice for Concrete Road Bridges” for understanding both the codes.
