Q. Write short notes on Numerical rating of Bridges?

In the numerical rating system, the condition of a bridge is represented by a number consisting eight digits. This eight digit number is called as unique rating number ( URN ).

In this eight digit URN, the first digit describes the over all condition of the bridge and this number is known as over all rating number ( ORN ).
The remaining seven digits are known as condition rating number ( CRN ) and these describes the physical condition of the different components of the bridges.
