On Monday, the MTA’s Traffic Mobility Review Board will review options for the tolls’ costs and carve-outs. The group is expected to make a recommendation on a tolling scheme next month, which must be approved by the full MTA board. MTA officials received requests for 122 types of exemptions, the agency confirmed. Key to each scenario is who must pay the tolls – and how many times they must do so each day for entering and exiting the toll zone.
