Metrobus schedules will change for dozens of routes across the D.C. region starting Sunday.

As part of the changes, Metro is introducing a new bus route that will provide additional connections between Fort Drum and the Southern Avenue Metro station. Riders also will see significant bus service restructures in the McLean-Crystal City Line, the North Capitol Street line, and in some routes serving Laurel in Prince George’s County.

The changes are part of Metro’s Better Bus initiative and are intended to make service more frequent, increase capacity and expand hours of operation.

In the District, bus riders in Northeast will have to pay extra attention when boarding the No. 80 at Fort Totten.  During most hours of the day on weekdays, every other trip departing Fort Totten will end at McPherson Square instead of going all the day to the Kennedy Center.

The new W1 route, Shipley Terrace-Fort Drum, will provide service between Fort Drum, The Shops at Park Village, THEARC, Southeast Tennis and Learning Center, Congress Heights Station and Southern Avenue Station. It will operate weekdays between 5:45 a.m. and 8:15 p.m.

Weekday service will be increased on the W4 route, Deanwood-Alabama Avenue, to reduce crowding.

In Maryland, Metro is extending weekday evening service on Route 89 in Laurel.  Metro says buses will provide service until at least 10 p.m. to addresses riders’ demand for more late evening service.

The No. 87, known as the Laurel Express, will extend from Greenbelt to New Carrollton to provide more connections between Laurel and the New Carrollton Metro station. Route 88 will be eliminated.

The A11 and A12 buses, which start in the District and travel along Martin Luther King Jr. Highway, will no longer serve the former Landover Mall site.

The limited-stop K9 route, serving New Hampshire Avenue, has been extended to the federal FDA-FRC complex in White Oak.

In Virginia, Metrobus bus is launching two new routes: the 10R will provide service every 30 minutes between Alexandria, Crystal City and Rosslyn during the weekday rush hour. Route 10S will replace Route 9E service during weekday rush hours between Rosslyn and Braddock Road Metrorail stations.

Routes 10A and 10E will serve the Pentagon and routes 10R and 10S will operate to Rosslyn, bypassing Pentagon and providing an alternative connection to Metro’s Blue Line.

A new bus route will provide weekend and holiday morning service from Union Station to Reagan National Airport.  The 13Y will replace all 13F and 13G service. It will operate between Reagan National and Union Station via Crystal City, Pentagon City, the Pentagon, 14th Street NW and E Street NW on Saturday, Sunday and holiday mornings until 7 a.m.

Also some changes will go into effect in the McLean-Crystal City routes.  Route 23A will provide service between Tysons Corner Center and Crystal City on weekdays during non-rush hours and all day weekends.  New routes 23B and 23T will provide service during weekday rush hours.

New route 23W, Westpark Shuttle, will provide service between Tysons Corner Center and Tysons-Westpark Transit Station serving Tysons Galleria until the Silver Line opens.
