Ramp - Switchback

Plan and elevation drawings of an ADA ramp with a switchback layout with dimensions for length and width

Switchback ramps are accessible ramps designed with a 180° change of direction along the accessible route. The inner handrail of a switchback ramp must remain continuous.

The landings of switchback ramps must maintain consistent minimum widths and depths of 60” (152.4 cm) along the entire change of direction running parallel to the ramp run. Landings with minimum lengths of 60” (152.4 cm) and widths consistent to the width of the ramp must be provided at the top and bottom of any straight run portions of the switchback ramp.

What is a switchback ramp?
A switchback ramp is an accessible ramp designed with a 180° change direction along the accessible route.
What is the minimum clear depth of a switchback ramp landing?
Switchback ramp landings shall have consistent minimum widths and depths of 60” | 152.4 cm along the entire change of direction.
What is the minimum size of a landing along a switchback ramp?
Switchback ramp landings are at least 60” | 152.4 cm deep with a length of at least the combined widths of both connected ramp runs (36” | 91.4 cm minimum widths each).

Ramps are inclined surfaces that join different levels of a space. Commonly used at the entrances of buildings to accommodate level changes, ramps provide building access to wheelchair users. The maximum slope of a ramp is calculated to provide comfortable and easy access to the building.
