Metro has reached a $2.2 million settlement in a class-action lawsuit over the agency’s MetroAccess service filed three years ago by a District-based anti-discrimination group.

The Equal Rights Center had alleged MetroAccess, a federally mandated transportation program for disabled riders, had violated both the Americans with Disabilities Act and the Rehabilitation Act through late pickups, unreasonably lengthy trips, discourteous drivers, no-shows and other problems, according to Arlene Corbin-Lewis, a spokeswoman for the group.
