Overbridges, Fly-Overs And Underpasses:

Railway Over-bridges

Railway Over-bridges (ROB) are structures constructed to enable the road traffic to go over the railway tracks.


Where one road crosses another road, and it is desired that they should not cross at the same level on the ground, a fly-over is constructed. One of the roads goes above the road it crosses, with sufficient clearance (about 5.0-5.5 m).


Underpasses are structures constructed to enable light vehicles, animals and pedestrians cross underneath a high speed facility. A clearance of 2.5-3.5 m is provided.
