Calcutta, Sept. 17 :    Calcutta, Sept. 17:  All vehicles plying on Vidyasagar Setu are having to pay increased toll tax since Saturday. Buddhadeb Mukherjee, vice-chairman of the Hooghly River Bridge Commissioners, said this was the second time since the bridge was opened on October 12, 1992, that toll tax had been hiked. The first time was in 1995. Mukherjee said the move is aimed at increasing the daily collection from the bridge. Moreover, maintenance cost of the bridge has increased threefold. According to the revised tax structure, a trailer carrying heavy goods will have to pay Rs 80, against the earlier Rs 70. For buses and trucks, the toll has been enhanced from Rs 40 to Rs 50 and for minibuses, Matador vans and tempos from Rs 20 to Rs 25. Private cars, taxis and jeeps will have to pay Rs 10 instead of Rs 7. However, for two-wheelers, there is only Re 1 increase from the existing rate of Rs 2. The daily collection from the bridge ranges between Rs 2.80 lakh and Rs 3 lakh. 'We will be able to collect around Rs 5 lakh daily now,' Mukherjee said.
