Ramp Handrails - Vertical

Vertical ramp guardrails are common safety systems used for accessible ramps that combine required handrails with a guardrail made up of a series of vertical balustrades. Vertical guardrails must double as both an assistive handrail and a guardrail that prevents users from accessing the edge of the ramp. For edge protection, vertical guardrails are made up of a balustrades that must be spaced to continuously prevent the passage of a 4” | 10.2 cm diameter sphere.

Handrails along both sides of a ramp are required on any ramp system with a rise greater than 6” | 15.2 cm or a horizontal run greater than 72” | 182.9 cm. The top grippable surface of any ramp handrail must be set at a height between 34”-38” | 86.4-96.5 cm above the ramp surface and a minimum clear width of 36” | 91.4 cm must be provided between handrails. In situations where a handrail is not continuous, handrails must extend at least another 12” | 30.5 cm parallel to the flat surface of the ramp landing. Inner handrails on a switchback or turned ramp must always be continuous. The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post.

Ramp - Turning

Turned ramps are accessible ramps designed with a 90° change of direction along the accessible route. The landings of turning ramps must have minimum widths and lengths of 60” | 152.4 cm in both directions at the moment that the turn occurs. The size of these landings provides adequate mobility for a wheelchair user to comfortably rotate according to the change in direction. The inner handrail along a turning ramp must remain continuous. 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 turned ramp.

Ramp Widths
Dimensioned drawing measuring the minimum widths and clearances of an ADA ramp

ADA accessible ramps must maintain a minimum clear width of 36” | 91.4 cm at all times. The cross slope along the width of any ramp must be less than 1:50 | < 2%. The 36” | 91.4 cm clear width must be maintained between all including handrails. Ramp surfaces should constructed as slip-resistant, stable, and firm systems.

Ramp Handrails - Utility

Utility ramp handrails are common all-in-one safety components used along any accessible ramp that typically provide user assistance and protection from falling off a ramp. As free-standing elements, utliity handrails must double as both an assistive handrail and a guardrail that prevents users from accessing the edge of the ramp. For edge protection, utility handrails must include either curbs or barriers at a minimum of 4” | 10.2 cm high along the ramp edge, or an integrated parallel bar at the bottom of the handrail that would restrict the passage of a 4” | 10.2 cm diameter sphere.

Handrails along both sides of a ramp are required on any ramp system with a rise greater than 6” | 15.2 cm or a horizontal run greater than 72” | 182.9 cm. The top grippable surface of any ramp handrail must be set at a height between 34”-38” | 86.4-96.5 cm above the ramp surface and a minimum clear width of 36” | 91.4 cm must be provided between handrails. In situations where a handrail is not continuous, handrails must extend at least another 12” | 30.5 cm parallel to the flat surface of the ramp landing. Inner handrails on a switchback or turned ramp must always be continuous. The ends of any handrail should be rounded or returned smoothly to the floor, wall, or post.

Ramp - Switchback

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

Straight run ramps are accessible ramps designed without any changes in direction along the accessible route. Requiring landings at both the top and bottom of the ramp run, straight run ramp landings must maintain widths that are at least the dimension of the ramp runs connected to it. The length of landings along a straight rump ramp must be at least 60” | 152.4 cm.
