  India)
• Via Ashuganj (Bangladesh) 856 KM (river) 115
  KM (road India Bdsh)
• Ashuganj route has been selected because river
  route is navigable through out the year and road
  route passes through generally plain land leading
  to less risk in transportation.
• Honble Prime Minister of Bangladesh during her
  visit to India in Jan-10 agreed to allow movement
  of ODC through Ashuganj in Bangladesh. Since
  then, Ashuganj has been included in Indo-Bangla
  Water Transport Proto-call and MOU has been
