The Americans with Disabilities Act did not exist in 1977. In Chicago, a 23-year-old broke her neck and found the city locked.
Marca Bristo was a flight attendant who spent her days walking the narrow aisles of commercial airplanes. On a summer afternoon, she jumped into Lake Michigan from a concrete breakwater. The water was shallower than it looked. She severed her spinal cord. She was paralyzed from the chest down.
She spent six months in a specialized rehabilitation hospital. She had to learn how to operate a manual wheelchair, how to shift her weight to prevent pressure ulcers, and how to breathe with compromised abdominal muscles.
The hospital environment was designed specifically for her. The doorways were wide. The bathrooms had steel grab bars. The floors were perfectly level.
Then she was discharged.
She tried to resume her life in Chicago. The physical barriers were absolute.
Curbs at intersections were six inches high. To cross a street, she had to roll her chair into active traffic lanes to find a sloping driveway, then wheel back against the flow of cars.
Public buses had steep metal steps. Train stations were subterranean, accessible only by long concrete staircases.
Payphones were mounted at head height. Public restroom stalls were exactly twenty-four inches wide. A standard wheelchair is twenty-five inches wide. Heavy spring-loaded doors required fifteen pounds of force to pull open.
She could not get into her own apartment building.
She lost her job. She lost her employer-sponsored health insurance.
To secure basic medical assistance, she had to navigate a state welfare system that required mandatory in-person interviews.
The public aid office was located on the second floor of a municipal building. The building had no elevator.
If she couldn't get upstairs, she couldn't register for benefits. If she didn't get benefits, she couldn't afford her daily medical supplies.
She arrived at the building on a Tuesday morning. The stairwell was steep and narrow.
Two friends had accompanied her. They had to carry her up the stairs in her chair.
One friend gripped the front wheels. The other gripped the back push-handles.
They tipped her backward at a forty-five-degree angle. She stared at the acoustic ceiling tiles as they hauled her up, step by step, the metal frame of the chair clanking against the concrete.
Halfway up the flight, the friend holding the back handles slipped.
The chair jolted downward. Her catheter bag shifted violently under her clothing and leaked onto her jeans.
She reached the second floor. She sat in the public waiting room for two hours in damp clothes.
The clerk behind the desk did not look up when she finally rolled to the counter.
The clerk handed her a stack of standard intake forms.
She realized the building was not simply old. The architecture itself was a rejection.
At the time, the 1968 Architectural Barriers Act applied strictly to facilities constructed with direct federal funds. Private businesses, local transit authorities, and municipal buildings were entirely exempt. Section 504 of the Rehabilitation Act of 1973 technically prohibited discrimination, but the government had issued no regulations to enforce it. The Chicago building code made no mandatory provision for wheelchair access in existing structures. A person who could not walk was legally considered a fire hazard in theaters and restaurants. The disability rights movement was still in its infancy, and the built environment operated on a simple, unwritten administrative premise: public space was reserved for the able-bodied.
The system worked exactly as it was designed to work.
Cities did not want to spend municipal budgets retrofitting miles of concrete sidewalks.
Transit authorities argued that installing hydraulic lifts on buses would slow down route times and decrease efficiency.
Business owners claimed that adding ramps would ruin historical brick facades and consume valuable retail floor space.
The logic was purely economic. The financial cost of altering the world was deemed higher than the value of the citizens excluded from it.
Bristo read the municipal codes. She saw the math.
She attempted to attend a city council meeting to protest the lack of accessible transit.
The meeting was held in a public hall downtown.
The entrance to the hall had four heavy marble steps.
She sat at the bottom of the steps in the rain while the council voted inside.
She stopped asking for permission.
In 1980, she founded Access Living. It was the first independent living center in Chicago run by and for people with disabilities.
She did not run it like a medical charity. She ran it like a political war room.
They rented office space. They had to construct a wooden ramp over the front steps just to get inside their own headquarters.
She bought a modified van with a rear hydraulic lift. The lift motor burned out twice in the first month.
She drove across Illinois, gathering people who had been locked in nursing homes, institutionalized by the state, or hidden in back bedrooms by embarrassed families.
They trained individuals to advocate for their own housing. They filed lawsuits against inaccessible public facilities.
They started appearing at transit board meetings.
When the city refused to listen, they escalated.
When buses without lifts stopped at major intersections, Bristo and her group wheeled into the crosswalks.
They parked their heavy chairs directly in front of the massive rubber tires. They refused to move.
Traffic backed up for miles down Michigan Avenue.
Police officers arrived and threatened to arrest them for disturbing the peace.
But the police transport vans were not wheelchair accessible. The officers could not physically transport them to the precinct.
The protests made the evening news. But protests did not rewrite building codes.
Bristo began drafting legal language. She stopped writing requests and started writing mandates.
She demanded a comprehensive civil rights bill, not a medical charity provision.
She joined the National Council on the Handicapped. She became one of the primary architects of the early drafts of what would become the Americans with Disabilities Act.
She demanded that every public door, every sidewalk, and every public telephone in the country be altered.
The business lobbies fought back relentlessly. They cited crushing construction costs. They cited the regulatory burden on small businesses.
The Greyhound bus company argued that making their fleet accessible would bankrupt the transit industry. The National Federation of Independent Business stated that the required alterations would destroy small enterprise.
They argued that society could not afford to rebuild itself for a minority.
She traveled to Washington. She testified before Congress. She brought the math of exclusion.
She testified about the courthouses that required carrying.
She testified about the public schools that turned children away at the door.
She testified about the city buses that drove past people waiting in the snow.
The architecture wasn't an accident. It was a decision.
The drafting process took years. Every clause was contested.
Lawmakers tried to insert loopholes for existing buildings. They tried to exempt private transportation companies.
Bristo and her colleagues went line by line through the revisions. They refused to let the bill be watered down into a set of optional guidelines.
She argued that physical access was not a medical issue. It was a civil right.
A staircase was a form of discrimination. A narrow bathroom door was a segregation tactic.
The Americans with Disabilities Act was signed into law on July 26, 1990.
It was the most sweeping civil rights legislation passed in the United States since 1964.
It mandated curb cuts on every intersection in America. It required elevators in multi-story public buildings. It forced municipal transit authorities to purchase accessible buses.
Concrete was poured in every city. Heavy doors were widened. Miles of ramps were built.
Marca Bristo watched the physical landscape of the country change permanently.
She died in 2019.
Today, the curb cuts she fought for are everywhere. Delivery drivers use them for hand trucks. Parents use them for strollers. Travelers use them for rolling suitcases.
Most people who use the ramps never notice them.
The Chicago transit system is currently undertaking a multi-decade project to update its rail stations.
As of this year, forty-two of the city's train stations still only have stairs.
