D.C. officials approved a proposal for a new pedestrian guide and mapping system along the National Mall, but didn’t get the expanded low-cost bus service there that they wanted.

The D.C. Circulator offers $1 rides along the Mall on weekends. But the National Capital Planning Commission on Thursday said running the bus on weekdays, too, should be part of the National Park Service plan that aims to improve visitor navigation of the Mall and East Potomac Park.
