Commercial vehicles entering Delhi will have to pay more toll tax from May.
The Municipal Corporation of Delhi (MCD) had approved a 17-28% hike in the rates under various categories in December 2010.
The MCD has now initiated the process of engaging a new contractor for collection of tax, as well as upgrading and maintaining 121 toll booths at various entry points.
With the term of the present contract expiring in May, the civic agency has asked eligible contractors to apply.
The work of collecting tax would be granted for a period of three years by the MCD.
"The selected contractor will have to collect tax, develop toll plazas, upgrade or modify the plazas on behalf of the MCD, at its own cost," said a senior MCD official.
Under the new rates - to be applicable from May - buses, trucks and other such vehicles, which are paying Rs 70 at present, will have to pay Rs 85.
The rate for six-wheel trucks has been increased from Rs 140 to Rs 165, that for 10-wheel trucks from Rs 280 to Rs 330 and for 14-wheel trucks from Rs 700 to Rs 820.
The civic agency, in its request for proposal, has specified that companies with prior toll collection experience would be considered by it.
Toll tax is an important source of revenue for the civic agency.
According to the civic agency, on an average, more than 22 lakh commercial vehicles enter Delhi everyday.
Last month, the Opposition in the MCD had alleged that contractors were charging the public more tax than prescribed.
Congress leader Jai Kishan Sharma had said that instead of R25 for commercial taxis, contractors were charging Rs 35.
