As of June 2010, Zhoushan residents are free from this toll, but vehicles from other regions still need to pay the fee. Speed limitations Given the road condition, the speed limitation from Zhoushan to Lidiao toll gate is while the speed limitation from Lidiao to Cezi toll gate is , which also raises dispute because of the high toll.
