Bridges, ROBs & RUBs
JNL builds important, major and minor railway bridges and the grade separators that replace level crossings.
How we deliver
Bridges set the pace of a railway project. We build river bridges on well and pile foundations, launch open-web and bow-string girders over running lines in planned traffic and power blocks, and push precast boxes under live track to create subways without closing the line. Our structures are built to Research Designs and Standards Organisation (RDSO) specifications and Railway-approved drawings.
What we do
- Important and major bridges over rivers, on well and pile foundations
- Viaducts for new lines and sidings
- Road Over Bridges (ROBs) with composite, bow-string and open-web steel girders
- Road Under Bridges (RUBs) and Limited Height Subways (LHS), cast-in-situ and precast, including box pushing
- Launching of open-web girders
- Bridge rehabilitation: replacing old steel girders with PSC slabs under traffic
Track record
- 100 major and 500 minor bridges in five years
