Is NYC's congestion pricing working to improve traffic in Manhattan? Here's a look at the MTA data for the first three weeks.

Drive times into Manhattan have dropped dramatically since the institution of New York’s congestion tolling program, according to data released Wednesday by the MTA — with the most significant improvements at the Holland Tunnel.

The analysis did not include changes to travel speeds on the George Washington Bridge or Cross-Bronx Expressway. The environmental assessment published by the MTA before the tolls launch expected traffic in those areas to increase slightly as drivers tried to circumvent the congestion pricing fees.
