Americans with Disabilities Act (1990)
Congress passed the ADA, requiring public transit to be accessible to people with disabilities. New construction had to comply, but existing stations were held to a looser 'program access' standard, so most stations built before 1990 stayed inaccessible.
Transit agencies added elevators and ramps to new projects and major renovations, but most older stations remained out of reach.
Decades later, agencies like the CTA face retrofits costing tens of millions per station — the direct legacy of the ADA's grandfathering of old infrastructure.
The ADA is the legal mandate behind the CTA's All Stations Accessibility Program. The California station's $40 million retrofit is one small piece of that unfinished obligation.
