The board of San Francisco's Municipal Transportation Agency has approved a 1.8 billion dollar budget for the next two years that increases fares for adults, provides free Muni passes for low-income eighteen year olds and eliminates metered parking on Sundays. The board will consider free Muni passes for seniors and the disabled pending a review of the agency's fiscal health next year. The budget’s approval comes amid increasing public pressure to make municipal transit more affordable for low-income riders. Nick St. Charles filed this report.
