When a new bridge [pl ignore, the small ones] is built, the users have to pay toll tax for sometime [it ranges to several years in rural localities, no idea whether it goes to government or the contractors and their henchmen]. The contractors collect some amounts as per the vehivle size. But, when a bridge [don't say, it's SEA LINK] has been built in Mumbai, it should be in elite class, and so it's fees, for different purposes.
