A spiral ramp is a type of sloped pathway that winds around a central point, allowing for gradual elevation changes. These ramps are often used in parking garages, stadiums, and other structures where space is limited. The design helps vehicles or pedestrians ascend or descend without the need for stairs or elevators. Spiral ramps can be made from various materials, including concrete and metal, and are designed to accommodate different traffic types. They provide a smooth transition between levels, making them accessible for people with mobility challenges, in line with the principles of universal design.
