Metrobus service on 913 routes was changed when the transit authority opened the subway's Blue Line between National Airport and Stadium Armory. In a two-stage operation, the agency prepared new schedules for 112 routes, revised or prepared new timetables for 168 routes and published more than a million timetables and flyers describing the new routes for passengers. More than 400 bus stop signs were changed.

Since the last change related to the opening of the Blue Line was made Sept. 6, planners have added 64 trips in the District, two in Maryland and 14 in Virginia. Service adjustments on 14 Virginia routes were made and 12 trips were discountinued.
