The Ministry of Road Transport & Highways has inventoried 1,72,517 bridges/structures under Indian Bridge Management System (IBMS).

Indian Bridge Management System (IBMS):

  • The IBM System has been established to develop the data in digital form, to identify, survey and inventorize the number of bridges and other structures on National Highways.
  • It crucially aims to identify the distressed bridges which need immediate attention and to sensitize the concerned implementation agency for taking corrective measures such as repair, rehabilitation reconstruction/new construction etc.

Inventory process for Bridge Location Number:(IBMS):

  • During inventory creation each bridge is assigned a unique identification number or National Identity Number based on the state, RTO zone and whether it is situated on an National Highway, State Highway or is a district road.
  • Then the precise location of the bridge in terms of latitude-longitude is collected through GPS and based on this, the bridge is assigned a Bridge Location Number.
  • Thereafter, engineering characteristics like the design, materials, type of bridge, its age, loading, traffic lane, length, width of carriage way etc are collected and are used to assign a Bridge Classification Number to the structure.
  • These are then used to do a structural rating of the structure on a scale of 0 to 9, and each bridge is assigned a Structural Rating Number.
  • The rating is done for each component of the structure like integral and non-integral deck, superstructure, substructure, bank and channel, structural evaluation, deck geometry, vertical clearance, waterway efficiency etc.
  • In addition to the structural rating, the bridges are also being assigned Socio-Economic Bridge Rating Number which will decide the importance of the structure in relation to its contribution to daily socio-economic activity of the area in its vicinity.
