Compendium of ROB Girder Drawings BS 132 issued by RDSO

Road Over Bridges (ROBs) are key components of any Road network. Ambitious expansion of road network in the Country requires construction of ROBs on a large scale. Indian Railways has also embarked on a mission to eliminate manned level crossings to improve mobility and safety in train operations. Thus, fast track and cost-effective construction of ROBs across the Indian Railway network is need of the hour.

Road Over Bridges (ROBs) are key components of any Road network.
Ambitious expansion of road network in the Country requires construction
of ROBs on a large scale. Indian Railways has also embarked on a mission
to eliminate manned level crossings to improve mobility and safety in train
operations. Thus, fast track and cost-effective construction of ROBs across
the Indian Railway network is need of the hour.
The above objectives can be achieved only through meticulous planning and
adoption of cost effective design and construction methodologies. In a step
forward, RDSO has prepared this Compendium for Road Over Bridges on
Indian Railways with an aim to disseminate good practices in planning of
ROBs, launching operations and to create a repository of drawings in use
over Indian Railways. It will not only save precious time but also avoid the
duplicity of efforts in developing designs for each ROB. The fact that 188
drawings included in the Compendium have been approved by Zonal
Railways should obviate the need for approval if they are to be used. Apart
from this, 30 RDSO standard drawings have also been included in this
Compendium. All these drawings are to be adopted for Railway portion
spans only.
The Compendium is being issued in the form of RDSO Report No. BS-132
for use over Indian Railways. It is hoped that Zonal railways, NHAI, State
Governments, etc. will get benefitted from the Compendium for expeditious
execution of ROB Projects.
