Early data from the Metropolitan Transportation Authority suggests that traffic has dropped around Manhattan’s core.

Traffic entering Manhattan below 60th Street dropped by 7.5% in the first week after the start of a controversial $9 toll on driving in that area.

If these trends hold, motorists willing to pay the $4.50-$14.40 toll to enter the congestion zone in the centre of the US’s busiest city will save thousands of hours per year they currently waste crawling through smoggy tunnels or over clogged bridges.

Days into the new charges, some restaurant owners say suppliers are raising prices. Others are giving customer discounts, and many fear the fallout for workers.

With the first week of New York’s Congestion Pricing toll in the books, commuters are reaping a reward, spending less time in traffic in exchange for their $9 toll to enter lower Manhattan, said the Metropolitan Transportation Authority.
