Minneapolis-St. Paul International Airport has installed 3D tactile maps across every one of its 149 public restrooms, becoming the first airport in North America to roll out the technology facility-wide so blind and low-vision travelers can find toilets, sinks, and stalls on their own. The raised, geometric maps are mounted near restroom entrances and let travelers trace a path with their fingers instead of guessing their way around an unfamiliar layout.
The idea grew out of a basic physical challenge: among MSP's 149 restrooms, only two share an identical floor plan, according to CBS News Minnesota. That variation, built up over decades of terminal expansions, turned a routine bathroom trip into a process of trial and error for travelers who cannot see the room. As CBS News reported, the new maps are designed to let visitors help themselves rather than depend on staff or strangers for directions once inside.
Each map measures roughly two by three feet and is mounted between 48 and 60 inches off the floor to meet Americans with Disabilities Act reach guidelines, according to the Metropolitan Airports Commission. Because no national design standard exists for tactile restroom maps, airport planners had to invent their own visual language from scratch.
Building a Symbol System From Nothing
Planners settled on custom geometric shapes — squares, triangles, lines, ovals, and diamonds — to represent toilets, urinals, sinks, and accessible stalls, the airports commission said. A raised-dot path guides a traveler's hand from a designated “start here” point at the entrance through the layout of the room. Standard tactile signage typically offers braille and high-contrast text describing what a room is, but rarely maps what's actually inside it, which is the gap MSP set out to close.
The push for the maps came directly from the people who would use them. Ken Rodgers, president of the American Council of the Blind of Minnesota, consulted on the project through the airport's advisory committee after telling airport executives about the hazards blind travelers face while searching for fixtures in unfamiliar restrooms, per the airports commission. More than 80,000 Minnesotans live with blindness or severe vision difficulty even with corrective lenses, according to Centers for Disease Control and Prevention data cited by the same account.
A Decade of Accessibility Projects
The restroom maps are the latest output of MSP's Travelers with Disabilities Advisory Committee, founded in 2014 to bring together disability advocates, airport staff, TSA officers, and airline personnel. The committee has guided nearly 25 accessibility projects over the past decade, per the airports commission's account. That track record helped MSP earn Level 3 accreditation from Airports Council International's Accessibility Enhancement Accreditation program in July 2023, at the time making it the highest-accredited airport for passenger accessibility in North America.
MSP has continued adding accommodations for other groups of travelers. In October 2024 the airport introduced real-time talk-to-text flight announcements on gate monitors and free on-demand Aira American Sign Language interpreting airport-wide, according to Simple Flying. Near Gate C16 in Terminal 1, the airport also maintains a permanent mock commercial aircraft cabin donated by Delta Air Lines, giving travelers with disabilities and guide dogs a chance to practice boarding, stowing luggage, and buckling seatbelts without the pressure of an actual flight.
Whether MSP's custom symbol set becomes a model other airports adopt remains an open question, as does how maintenance crews will keep the tactile maps accurate as restrooms are eventually renovated. For now, the airport says the project fills a gap that standard accessibility signage never addressed: not just naming a room, but mapping what's inside it.
