Dimensioned drawings of an ADA ramp with regulation landings for turning a corner
Description
Description

Turned ramps are accessible ramps designed with a 90° change of direction along the accessible route. The size of these landings provides adequate mobility for a wheelchair user to comfortably rotate according to the change in direction. This design is typically used in architectural or engineering projects where there is limited space for a ramp and a straight incline is not possible. The ramp may turn either to the left or to the right, depending on the layout and location of the building or structure. However, the sudden change in direction can be challenging for some users, so these ramps should be designed with caution and with accessibility in mind.

Dimensions & Sizes
Dimensions & Sizes

The Ramp (Turning) has a height of 24” (61 cm), total run length of 36’ (11 m), and overall width of 17’ (5.18 m). Dimensions will vary based on the desired slope and height needed.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. 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.

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 or <2%. The 36” (91.4 cm) clear width must be maintained between all including handrails.

The maximum allowable slope in any new construction is 1:12 with a maximum rise of 30” (76.2 cm) without a landing. A ramp with a slope between 1:12 and 1:16 can have a maximum horizontal length of 30’ (9.14 m) without a landing. A ramp with a slope between 1:16 and 1:20 can have a horizontal run up to 40’ (12.19 m) before requiring a landing.

Common Questions
Common Questions
What is a turning ramp?
A turning ramp is any accessible ramp designed with a 90° change direction along the accessible route.
What is the minimum clear landing size for a ramp that changes direction?
If a ramp changes direction, the landing must have a minimum width and depth of 60” (152.4 cm) in both directions.
How large is ramp landing that changes direction?
Ramp landings that provide a change of direction must be at least 60” x 60” (152.4 cm) with continuous inside handrails.

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.
