KATHMANDU: The locals obstructed the main road in Bouddha today as a sign of protest for the snail-paced road construction. The sorry state of the road -- the expansion works of which have been in a limbo for four years now -- has been troubling the locals as well as regular commuters. The intense protest today resulted in a clash between the locals and police personnel. The police fired tear gas shells to control the protestors. In the meantime, an alternative route from Chabahil to Maakalbari has been arranged.
