A curb ramp is a sloped surface that connects a sidewalk to the street, allowing for easier access for people using wheelchairs, strollers, or bicycles. These ramps are designed to eliminate the barrier created by a curb, making it safer and more convenient for individuals with mobility challenges to navigate urban environments. Curb ramps are typically made of concrete or asphalt and are often found at intersections or pedestrian crossings. They are an essential feature of accessible design, promoting inclusivity and compliance with regulations like the Americans with Disabilities Act (ADA) in the United States.
