So far, NYC congestion pricing has NOT increased traffic on highways outside of the congestion zone.
Summary: Traffic declined a lot within the congestion relief zone, AND it's flat in other areas where you'd expect traffic to be diverted to.
It's a win-win!

FWIW, in SF after fwys were demolished in the 1990s a good share of the citywide car travel reduction measured was in trips not made and more trips chained.
