There is no possibility of opening the flood-ravaged Kaziranga National Park to tourists from November 1 since nearly 200 roads inside the park and 178 km of the main road have been severely damaged . Bsides, 25 bridges and 15 culverts have also been severely damaged. There have been heavy siltation and the park is under knee-deep mud in several places. The authorities are, therefore unable to estimate the damages, sources said. They have, however, expressed the hope that if Rs 50 lakh is received immediately as promised by the Chief Minister, repair works can be taken up.
