| Remarks
: |
- ROB was constructed at the location of existing
level crossing. The site falls in the busiest
highway of Ahmedabad - Mehsana.
- The site of work was not continuously available
due to limited space.
- Superstructure work consisting of continuously
RCC solid slab was carried out over Railway
Track by providing special staging arrangement
and conventional staging was adopted for spans
away from Railway Track.
- The work close to Railway Track has to be
done with utmost safety.
- The work involved intricacy of skew bridge.
(Angle of skew being 55°)
- Reinforced earth work was carried out using
precast facia panels and GI strips.
