Final answer:
Accessible routes less than 60 inches wide require a passing space every 200 feet to allow individuals with mobility devices to pass each other, as per ADA guidelines.
Step-by-step explanation:
Accessible routes that are less than 60" wide must provide a passing space every 200 feet. These passing spaces allow individuals using wheelchairs or other mobility devices to pass one another safely and are a requirement under the Americans with Disabilities Act (ADA) Accessibility Guidelines. These spaces should be at least 60 inches wide and either 60 inches long or in the form of an intersection of two walking surfaces that provide a T-shaped space.
