Round

The rounding off is to the nearest multiple of five at toll plazas, the official said, adding that stretches 

1. where the fee amounted to Rs 68 or 69 will now be charged Rs 70, 
2. while on stretches where it is Rs 62, Rs 60 could be charged.

The move, the official said, will significantly reduce long queues on account of tolls.
