Starting just after midnight on Sunday, drivers began paying a new fee to enter the heart of Manhattan. The toll is part of New York City’s plan to reduce some of the world’s heaviest traffic while raising billions of dollars to pay for improvements to mass transit.

Congestion pricing is now in effect in NYC, and drivers faced the first weekday commute with the controversial new tolling system.

New York is now charging a $9 toll during daytime hours for passenger vehicles driving in Manhattan south of 60th Street as part of the United States’ first-ever congestion pricing plan.
