Routes: Kolkata – Ashuganj – Palatana Kolkata – Karimgunj - Palatana
![Page 30: January 17, 2011 otpcindia New Delhi](https://reader036.vdocuments.mx/reader036/viewer/2022062520/568159d1550346895dc72293/html5/thumbnails/30.jpg)
Routes for transportation of ODCs from Kolkata: There are two routes available for transportation of ODCs to Palatana site:
Via Karimganj: 1318 KM (river) + 320 KM (road - India)
Via Ashuganj (Bangladesh): 856 KM (river) + 115 KM (road – India + B’dsh)
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.
Hon’ble 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 signed with GOB formally allowing movement of ODCs through Bangladesh territory.
96 ODCs shall be transported through Bangladesh for which construction of RO-RO jetty at Ashuganj and bypasses between Ashuganj and Palatana has started.
Construction of bypasses in between Ashuganj (Bangladesh) and Palatana (Tripura) has commenced and movement of ODC from Kolkata to Ashuganj expected to start from 20-Jan-11 and from Ashuganj to Palatana site by 15-Feb-11.
