The MTA has unveiled a new subway map for riders, marking the first “major redesign” since 1979, agency chair and CEO Janno Lieber said Wednesday.

The revamped map has a “diagrammatic style, employing bold, straight lines making it much easier for the eye to follow and more suitable for digital users,” the MTA said in a release.

At a news briefing, Lieber said the redesign was “years in the making.”

“The result is a map that is much easier to read, but also reflects all the enhancements that we’ve made over the years, but it still preserves the spirit of the previous versions,” he said. “It is not every day that we get to unveil a new New York City icon.”

The MTA said the new map will offer travel information to straphangers in an “easily readable, bright, bold and orderly manner.”

“The white background, bold colors, horizontal writing and use of black dots make the map more ADA-friendly and easier for persons with visual limitations and cognitive disabilities to read,” the agency said.

Designers prioritized legible text, using single lines where possible, leaving open space to avoid crowding, and using black and white icons for optimal readability, it added.

The MTA said the map legend is “more detailed, and includes accessibility, transfer, and safety information, as well as a QR code that leads users to the MTA website.”

Designers were inspired by previous maps, the agency said — keeping the “official brand colors” used for the 1979 and 1998 Hertz maps and embracing a “geometric and diagrammatic aesthetic” reminiscent of the 1972 Vignelli diagram.

The MTA is already displaying the new map on digital screens in subway stations, and will soon roll it out on R211 cars, the release said.

“Replacing physical maps in the remaining subway cars will be done in phases over the coming weeks,” it added.

Riders will be able to download both the new map and older versions on the MTA’s website.
