2013 Forest Service Trail Accessibility Guidelines (FSTAG)

7.4.5 Passing Spaces.

Trails with a clear tread width less than 60 inches (1525 mm) shall provide passing spaces complying with 7.4.5 at intervals of 1000 feet (300 m) maximum. A passing space must also be provided at the end of any segment of trail that meets the requirements of 7.4, if the full length of the trail does not meet the requirements. Passing spaces and resting intervals may coincide or overlap.

7.4.5.1 Size.

The passing space shall be either:

• A space 60 inches (1525 mm) minimum by 60 inches (1525 mm) minimum; or

• The intersection of two trails providing a T-shaped space complying with ABAAS section 304.3.2 where the base and the arms of the T-shaped space extend 48 inches (1220 mm) minimum beyond the intersection. Vertical alignment at the intersection of the trails that form the T-shaped space shall be nominally level.

7.4.5.2 Slope.

The cross slope of a passing space shall not exceed 1:20 (5 percent) in any direction.

7.4.5.3 Non-complying Segment Ends.

Where a segment of the trail does not comply with 7.4, a passing space shall be located at the end of each adjacent trail segment that does comply with 7.4.
