Indian Bridge Management System

The Ministry of Road Transport & Highways has inventoried 1,72,517 bridges/structures under Indian Bridge Management System (IBMS). It comprises of 1,34,229 culverts, 32,806 minor bridges, 3,647 major and 1,835 extra-long bridges.

About IBMS

Indian Bridge Management System (IBMS) was launched by the Ministry of Road Transport & Highways to create an inventory of all bridges in the country and rate their structural condition so that timely repair and rehabilitation work can be carried out based on the criticality of the structure.
Lack of clear objective database on bridges in the country has led to a situation where the authorities were neither clear about the exact number and location of the bridges nor they were able to maintain this asset in proper working condition. IBMS has been brought in to address this anomaly.
The inventory under IBMS comprises of:

  • Under the IBMS, each bridge is assigned a unique identification number or National Identity Number based on the state, RTO zone and whether it is situated on a National Highway, State Highway or is a district road.
  • The precise location of the bridge in terms of latitude-longitude is collected through GPS and based on these, the bridge is assigned a Bridge Location Number.
  • Engineering characteristics like the design, materials, type of bridge, its age, loading, traffic lane, length, the width of carriageway etc are collected and are used to assign a Bridge Classification Number to the structure.
  • The Engineering characteristics 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.
  • Socio-Economic Bridge Rating Number will be assigned based on the importance of the structure in relation to its contribution to the daily socio-economic activity of the area in its vicinity.

Based on the following data from inventory, IBMS will analyse data and identify bridges that need attention. Also, an inspection will be carried out wherever required to improve the operational availability of the structure, enhance its life and prioritize repair and rehabilitation work.
