Public transportation has been transformed by the coronavirus pandemic. Light rail is shut down, and bus service is concentrated on core lines.

The San Francisco Municipal Transportation Agency’s Director Jeffrey Tumlin and Julie Kirschbaum, the agency’s Director of Transit, explain how Muni has adapted to the pandemic and some of the changes ahead.
