Last month, we told you that the blue Metro Connection buses which run between Rosslyn and Dupont Circle would switch over to Circulator status on September 1. But the beginning of service has been pushed up slightly, and will begin this Sunday.

The Circulator website has provided the above map to show you exactly where the stops are along the route. One thing to remember: the new Circulator line overlaps with the existing Georgetown-Union Station line along M Street between Wisconsin and Pennsylvania Avenues. If you’re picking up the Circulator in that part of Georgetown, you’ll have to double-check that the Circulator you’re boarding is the right one, so that you don’t head up Wisconsin instead of over the Key Bridge, or vice versa.
