The MTA on Wednesday unveiled a new “easily readable” New York City subway map for the first time in nearly 50 years – but straphangers knocked the redesigned graphic as a “complicated” brain teaser that impedes their ability to navigate the underground rail system.

The Metropolitan Transit Authority has unveiled the first major change to the famed New York City subway map since 1979. The historic map commuters are used to seeing on subway cars and in stations across the five boroughs will be phased out in the coming weeks and replaced with the new version.

The MTA Wednesday released the first wholesale update of the NYC Subway map in more than 50 years, reminiscent of the iconic 1972 subway map designed by Massino Vignelli.
