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. It is the most basic and straightforward type of ramp design, and is used in many architectural and engineering projects where there is ample space and a gentle incline is desired.
The Ramp (Straight) has a height of 12” (30.5 cm), total length of 17’ (5.18 m), and width of 36” (91.4 cm). The length of landings along a straight rump ramp must be at least 60” (152.4 cm). Dimensions will vary based on the desired slope and height needed.
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.
