The collection of toll on Bengaluru-Mysuru expressway began at Gananguru in Srirangapatna taluk of Mandya district on Saturday.
The start of toll collection was, however, marked by a protest by Kannada organisations, who staged a demonstration near the toll plaza and shouted slogans against the Centre and the State government.
They opposed the collection of toll by National Highways Authority of India (NHAI) without completion of pending works. Police personnel were also deployed at the toll plaza to prevent any untoward incident.
