Private taxi drivers, workers of Kannada outfits and BJP held protests against the steep increase in toll on the 22-km stretch of the elevated road to the Kempegowda International airport.
The toll for a return journey by car or other such vehicles has been increased from Rs 30 to Rs 115 with effect from Saturday last, triggering protests.
The concessionaire of the public-private partnership project has been allowed to hike the toll in accordance with provisions of the agreement with the National Highways Authority of India, officials said.
Activists of Kannada outfit Karnataka Rakshna Vedike tried to lay siege to the toll plaza but were chased away by police.
