The DC Circulator will reach the end of the line on Dec. 31.

The public-private bus system’s demise is part of the city’s financial plan for fiscal 2025. Since 2005, it has operated via a partnership between the District Department of Transportation and company RATP Dev. Each bus ride costs $1.

Currently, the Circulator has six routes: from Dupont Circle to Georgetown and Rosslyn, from Georgetown to Union Station, from Woodley Park and Adams Morgan to Columbia Heights to the McPherson Square Metro station, between the Eastern Market and L’Enfant Plaza Metro stations, from Congress Heights to Union Station, and one route dedicated to the landmarks around the National Mall.

Starting Oct. 1, the Dupont Circle-Rosslyn route will be eliminated and late-night service will stop on the Woodley Park-McPherson Square and Georgetown-Union Station routes. Those two routes, plus the Congress Heights-Union Station and Eastern Market-L’Enfant Plaza routes, will stop service at 9 p.m. instead of midnight.

In addition, routes will start operating on 20-minute headways, an increase of 10 minutes from current arrival times. The National Mall route will continue operating daily until 7 p.m.

“We greatly appreciate the valuable service DC Circulator provided to the District over the past 18 years,” Acting DDOT Director Sharon Kershbaum said in a statement.
