If you take Metrobus, pay attention because some big changes are starting Sunday.

About 60 Metrobus routes are affected by changes going into effect Sunday, including the elimination of several routes, schedule adjustments and additions of Sunday service in some Greenbelt routes. Some changes preview this spring’s expansion of bus-only lanes in Arlington and the upcoming opening of two transit centers in Maryland.

Metro said it expects to soon take over the Takoma Langley Crossroads Transit Center, a project that has been in the making for more than a decade. With 12 bus bays, the Langley Park hub on the northwest corner of New Hampshire Avenue and University Boulevard will accommodate Metrobus routes C2, C4, F8, J4, K6 and K9 and buses run by the Prince George’s and Montgomery bus systems.  The transit center also is expected to be a future stop for the Purple Line, the proposed light-rail line that will connect Montgomery and Prince George’s.

Metrobus this spring will also rearranging service on routes J2 and J3 to serve the new Westfield Montgomery Mall Transit Center, scheduled to open in early May on the northeast corner of the mall.

In Northern Virginia, Metro is expected to expand its Metroway service to Pentagon City, just as Arlington County opens its portion of the Potomac Yard-Crystal City Transitway this spring. Metro says service between South Glebe Road and 26th Street will operate on the new Crystal City transitway. Arlington transportation officials declined to give an opening date for the bus-only lanes. The project is already a year behind schedule.

The spring bus changes are part of Metro’s Better Bus initiative and are intended to make service more frequent, increase capacity and expand hours of operation. Continue reading for details of what you can expect across the Washington region.

In the District, Metro will discontinue weekday night service and all weekend service on the Pennsylvania Avenue route 34. Transit officials say riders have the 30N and 36 as alternative options.

The U Street-Garfield route 93 will be discontinued because of low ridership, Metro said. The transit agency is adding early morning and late evening on routes 90 and 92.

Routes B8 and B9 serving the Fort Lincoln community in Northeast Washington will be extended to The Shops at Dakota Crossing Shopping Center (at New York and South Dakota avenues NE).  However, there will be less service during the mid-day– buses on the B9 will run every 70 minutes between 9 a.m. and 3:30 p.m.

Also in the Fort Lincoln area, the H6 (Brookland-Fort Lincoln) route will be extended to The Shops at Dakota Crossing Shopping Center.

Also in Northeast, the G8 Rhode Island Avenue buses heading to downtown will run more frequently between the Brookland-CUA station and Farragut Square during the morning rush hour. This could help decrease crowding during the morning commute. Buses will run every six to eight minutes. But if you board the bus in Avondale, at the Maryland-D.C. line, you will have to wait a little longer. The frequency of  buses between Avondale and Brookland will be reduced to every 15 to 20 minutes between 6:30 a.m. and 8:30 a.m. In the evening, buses in that stretch will run more often, every six to 12 minutes.

Other changes include:  A bus stop relocation at Franklin Square for the No. 43 (Mount Pleasant) and the No. 53 (14th Street) buses. Adjustments to timetables to routes 63 (Takoma-Petworth), 64 (Fort Totten-Petworth), A8 (Anacostia-Congress Heights), E2 (Ivy City-Fort Totten) and H8 and H9 (Park Road-Brookland).

In Maryland, some residents will get the Sunday service they have been requesting. Metro is adding Sunday service between the Greenbelt Metro and Langley Park on the C2 bus that runs from Greenbelt to Twinbrook. Riders in this part of Prince George’s have been asking Metro for the Sunday service. Buses will run every 45 minutes between 8:15 a.m. and 7:30 p.m.

Also in Greenbelt, riders should expect new Sunday service along with significant restructure of the G12, G13, G14 and G16 to New Carrollton. The G13 and G16 routes will be discontinued, and Metro says those trips will be picked up by the G14. New Sunday hourly service will be added to routes G12 and G14. The Sunday service will be between 6:30 a.m. and 10:30 p.m.

In nearby College Park, Metro will discontinue the route 81 bus and convert the 81 trips to operate as route 83 trips. Metro said riders going to the Greenbelt Metro on Sunday will be able to use the C2, G12 and G14. Meanwhile several route 82 trips will be discontinued– including one southbound trip in the morning and three northbound trips in the late afternoon.

The Laurel line (89, 89M) will be restructured to run on Baltimore Avenue and Ritz Way.

The following routes will be discontinued:  The R3 connecting Greenbelt to Prince George’s Plaza; the Z9 and Z29 from Laurel to Burtonsville will be replaced by the new route Z7; and the No. Z13 (Greencastle- Briggs Chaney Express); The V15 (District Heights-Seat Pleasant) will be eliminated and all its trips will become V14 trips. With the change, the service along Pepper Mill Drive and Hasting Drive will be discontinued and Sunday V14 service will be extended to operate between Penn Mar Shopping Center and Deanwood Metro station.

A number of bus routes serving the Paul S. Sarbanes Transit Center in Silver Spring will be reassigned bus bays.  Those include: J5 (Twinbrook-Silver Spring) will depart bus bay 218; Q1, Q2, Q4 (Veirs Mill Road) will move to bus bay 218; S2, S4 (16th Street) will serve bus bay 103; MetroExtra S9 (16th Street) will depart from bus bay 104; The Y2, Y7, and Y8 (Georgia Avenue-Maryland) will depart from bus bay 219; the Z2 (Colesville-Ashton) will be reassigned to bus bay 113; the Z6 (Calverton-Westfarm) will move to bus bay 113; and the Z8 (Fairland) will depart from bus bay 114.

The timetables of several of those routes will also be adjusted.  The Z6, for example, will add Saturday service between Silver Spring and Castle Boulevard, every 30 minutes. A new bus route, the Z7 (Laurel-Old Columbia Pike) will replace routes Z9 and Z29 and will connect South Laurel Park and Ride, the Towne Centre at Laurel, Laurel Employment Park, Burtonsville, Old Columbia Pike and Silver Spring. It will run every 30 minutes during the morning and afternoon rush hours.

Other changes include: The C8 from College Park to White Flint will be restructured; the timetable for the J7 and J9 (I-270 Express) will chance to better reflect actual travel time; and service frequency will be reduced to 30-35 minutes on the W19 (Indian Head Express).

In Virginia, the 3Y (Lee Highway-Farragut Square) will add one more trip to help relieve crowding during the morning commute.

In Arlington, Metro will end the 16H (Columbia Heights West-Pentagon City) service between Pentagon City and Crystal City. The transit agency said the route will be replaced by the new Metroway service extension.

The 16X (Columbia Pike-Federal Triangle) will be restructured:  the eastbound trip leaving the Pentagon at 6:55 a.m. will be converted to a full trip from Culmore to Federal Triangle, departing Culmore at 6:28 a.m.; three westbound trips leaving 11th and E streets (3:36 p.m., 4:06 p.m. and 7:14 p.m.) will be converted to full trips, ending in Culmore; and the 3 p.m. eastbound trip from the Pentagon Transit Center will be discontinued.

Other changes include:  The Friday and Saturday 3:30 a.m. trips on the 7A (Lincolnia-North Fairlington) will be discontinued; the 7Y service between Farragut Square and the Washington Convention Center will be discontinued;  The 7H (Lincolnia-Park Center-Pentagon) route will be eliminated; the 7X route will be shorten so all 7X trips will begin and end on Lincolnia Road and Quantrell Avenue in Lincolnia– and service to Arbor Park will be discontinued.
