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.
