DOWNTOWN TUNNELS FOR WHEELCHAIRS “Eighteen years after the Americans With Disabilities Act became law, several spots along the 6.5-mile downtown tunnel-skywalk system, used by more than 150,000 downtown workers, remain blocked or altogether inaccessible to those in wheelchairs. These areas haven’t been made ADA-compliant because it would be difficult or impossible to put in ramps and still leave enough headroom for pedestrians, said Bob Eury, director of the Downtown District, a public-private association that promotes and manages downtown development.” [Houston Chronicle]
