Curb Ramp

A sloped transition between a sidewalk and a street that allows wheelchair users, people with strollers, and others to cross without navigating a vertical curb. Curb ramps are essential infrastructure for pedestrian accessibility—their absence, poor maintenance, or improper slope (typically required to be 8% or less) can make routes impassable for wheelchair users. Standards like ADA and international equivalents specify dimensions, slope ratios, detectable warning surfaces, and placement requirements.
