The Metropolitan Transportation Authority approved a revised congestion pricing plan for Manhattan that President-elect Donald Trump has threatened to terminate once he takes office.

Slashing the original $15 toll raises questions about whether a smaller revenue stream could delay projects or lead to higher costs for New York’s public transit agency.

Kathy Hochul plans to revive a controversial congestion pricing plan for drivers entering Manhattan at 60 th Street and below by knocking $6 off the $15 toll she rejected in June. The new $9 toll would need to be approved by the Metropolitan Transportation Authority Board at a meeting next week.
