Such  works  are  prioritized  and  taken  up  on  the basis  of  its  impact  on  safety  and  mobility  in  train  operations  and impact on road users.

| Period            | ROBs/ RUBs constructed                                      |
|-------------------|-------------------------------------------------------------|
| 2004-14           | 4,148 Nos.                                                  |
| 2014-25 (June'25) | 13,426 Nos. (including 747 Nos. in the State of Tamil Nadu) |

Railways have taken following measures to expedite the progress of work:

-  Periodic meetings of Railway & State Government officials are done to resolve various issues related to ROB/RUB works.
-  Standardization of superstructure drawings for various combinations of span, skewness and width of road on Railway portion  has  been  done  to  avoid  delays  during  the  design approval.  This  has  been  issued  in  the  form  of  compendium, which  can  be  directly  adopted  for  Road  Over  Bridge  across Railway lines for expeditious planning.

Completion & commissioning of ROB/RUB works depends on following factors:-

-  Cooperation of State Governments in giving consent for closure of LC,
-  Fixing of approach alignment,
-  Approval of General Arrangement Drawing (GAD),
-  Land acquisition,
-  Removal of encroachment, shifting of infringing utilities,
-  Statutory clearances from various authorities,
