The curb cut · 1970s
Designed for wheelchair users. Used by everyone.
The curb cut movement began in Berkeley in the early 1970s, when disability advocates took to the streets with sledgehammers to create their own. When the ADA mandated them nationwide in 1990, they became standard infrastructure. Today parents with strollers, travelers, cyclists, and delivery workers use them without a second thought. What wheelchair users needed to cross a street is now the curb that millions depend on.
