I strongly feel that I will consider that the roads are cleaned only when the tons of soil lying in the middle and sides of the roads are removed and reduced air pollution. Though I have seen a mechanical vehicle for removing soil around five years back, I have not seen it working since past three years any where.
The main reason for so much soil on the roads is due to failure on the part of municipality that it digs roads but the soil removed as put on the roads are not at all cleaned as well as giving permission for dumping construction material for building structures by land owners during the period of entire construction which spreads along the roads and filled on the road
