“Half the theaters on Broadway, including some of its most famous stages, will become fully accessible to disabled people under an agreement announced Thursday between the landlord and the government. Work on the 16 landmark theaters operated by the Shubert Organization is to be finished by year’s end. The organization has spent $5 million over several years to improve wheelchair seating areas, restrooms, entrances, exits, ticket windows, concession areas and drinking fountains. But legalities formally bringing the theaters into compliance with the federal Americans with Disabilities Act were completed only this week.”
