Final answer:
The Americans with Disabilities Act (ADA) mandated that federally supported facilities increase corridor width to accommodate wheelchairs, as part of its wider aim to eliminate discrimination against individuals with disabilities and ensure accessibility in public spaces.
Step-by-step explanation:
The act that forced all federally supported facilities to increase corridor width to a minimum of 54 inches to accommodate wheelchairs is the Americans with Disabilities Act (ADA). The ADA was a landmark piece of legislation signed into law in 1990, which mandated accessibility in public buildings, transportation, and employment. It required public accommodations to be made accessible, which includes ensuring that corridors are sufficiently wide for wheelchair users.
Under the ADA, discrimination against individuals with disabilities in all areas of public life, such as in schools, workplaces, and all other places that are open to the general public, is prohibited. The ADA also made clear that all new construction and modifications must be accessible to individuals with disabilities. For existing facilities, barriers to services must be removed if readily achievable.
