Massachusetts Avenue Line

On August 25, 1984 when Friendship Heights station opened, routes N1, N2, and N3 was rerouted to terminate at the newly opened station.

A new N6 was also introduced to operate alongside the N2 and N4 but run during the late nights and weekends as a combination to routes N2 and N4 operating in the Wesley Heights Neighborhood alongside the N2 in the clockwise direction (going westbound) but remaining along Massachusetts Avenue going eastbound.

In 1996, routes N1 and N3 were eliminated and replaced by route N4 which was extended from its terminus from Westmoreland Circle to Friendship Heights station along Western Avenue.

On December 29, 1996, route N6 was eliminated and replaced by routes N2 and N4 which added late night and weekend service at frequencies of every 24-32 minutes during weekday peak periods in the counterclockwise direction, every 36 minutes weekdays between approximately 9:30 AM and 3:30 PM, every 40 minutes weekday evenings after 7:30 PM, and every 50 minutes on Saturdays and Sundays.[4]

In 1999, route N6 was reincarnated on its previous routing to replace the N2 and N4 during the late nights and weekends as both routes had low ridership during the post PM Peak hours and weekends. Route N6 would operate for the N2 and N4 as one route to fill the low demand the N2 and N4 had during the times the N6 will operate.

On June 25, 2000, route N2 was rerouted to operate along Wisconsin Avenue, Tenley Circle, and Nebraska Avenue instead of operating along Western Avenue as the route overlapped the N4. The reroute N2 would serve the Tenleytown neighborhood and Tenleytown–AU station plus give additional service for routes 30, 32, 34, 35, and 36 along Wisconsin Avenue and route M4 along portions of Nebraska Avenue. Service between Ward Circle and Cathedral and Massachusetts Avenues (to Farragut Square) plus Massachusetts and Idaho Avenues (to Friendship Heights) were unaffected.[5][6]

A new route N3 was also introduced to operate during the weekday peak hours in the peak direction between Friendship Heights station and Federal Triangle via the N4 routing along Western Avenue and Massachusetts Avenue, but turn onto 20th Place and operate along 23rd Street, Virginia Avenue, Constitution Avenue, and 12th Street terminating along Pennsylvania Avenue and 10th Street during the AM Peak Hours and beginning on 12th Street and Constitution Avenue during the PM Peak Hours.[5]

In 2010 during WMATA's FY2011 budget, WMATA proposed to eliminate the N3 as it overlaps other services and to only operate the N2 and N4 during the weekday peak hours. Route N6 would operate during the weekday midday hours with post PM peak hours and weekend service remaining unchanged. WMATA also proposed to reroute the N2 along Massachusetts Avenue, Westmoreland Circle, and Western Avenue from Ward Circle. Alternative service is provided by route M4 along Nebraska Avenue and Tenleytown station and routes 32 and 36 along Wisconsin Avenue.[7]

On September 25, 2011, route N2 was rerouted along Massachusetts Avenue, Westmoreland Circle, and Western Avenue via the N3, N4, and N6 routing in order to replace portions of route N8 which was eliminated. Service to Tenleytown–AU station and the N2 portion along Nebraska Avenue was discontinued.[8][9][10]

Route N3 was also rerouted from the Friendship Heights bus bays to begin/end at Western Avenue and Jenifer Street due to Friendship Heights reaching its bus capacity. Passengers would had to walk a short distance to the Mazza Gallerie Metro station entrance as a result.[9][10]

Many residents from Glover Park and Wesley Heights voiced frustration over the N2 reroute with residents losing direct access to Tenleytown–AU station. Brian Cohen, the chair of Advisory Neighborhood Commission 3B, told WMATA and DDOT representatives who attended a December 2011 meeting that as a public entity, metro's first obligation is to serve the public stated:[11]

It is unacceptable to make these kinds of changes without public input.

WMATA Bus planner David Erion told residents that the change to the N2 line was not "significant enough" to meet the legal threshold requiring public input. But many residents called Erion's statement pathetic and that both WMATA and DDOt has total disdain for both Glover Park and Wesley Heights. DDOT's Steve Strauss told neighbors that in making the changes, both his agency and WMATA assumed the community "wanted to maintain the Spring Valley connection."[11]

Other Glover Park residents argued that the impacts of inclement weather and insufficient lighting make some of the streets no longer served by the N2 difficult and potentially dangerous. Other common complaints were that the buses will switch suddenly from the N2 to the N4 without any notice, suddenly instead of going to Cathedral Avenue, they are driven farther down Massachusetts Avenue. Other Gloverk Park residents argued that the impacts of inclement weather and insufficient lighting make some of the streets no longer served by the N2 difficult and potentially dangerous.[11]

The Advisory Neighborhood Commission passed a resolution asking DDOT and WMATA to restore the N2 route prior to the September 2011 changes Commissioners reasoned that the change was made so quickly in the first place that the agencies should be able to just switch them back. DDOT and WMATA said it would not be so easy. Julie Hershorn, a manager from WMATA's Office of Bus Planning, said one issue is that a change in the bus system can have a domino effect. If the buses are "inter-lining," it is possible that, for instance, when N2 bus reaches the end of its route, it could become another line entirely.[11]

Due to the N2 reroute, Wesley Heights and Glover Park passengers wanting to go to Tenleytown would have to ride the N2 up to Ward Circle, then transfer to the infrequent M4 in order to reach Tenleytown. Passengers would then have to walk from the bus bays along Fort Drive and 40th Street to Wisconsin Avenue and catch the 32 or 36 to Friendship Heights to get off stops along Wisconsin Avenue. Or passengers were forced to ride the N2 all the way further to Friendship Heights station, then catch the 32, 36, or 37 buses for stops along Wisconsin Avenue and Tenleytown station. In all, passengers would need to transfer once or twice to reach their destinations.

Due to the controversial N2 reroute from customers, WMATA announced on December 9, 2011 that route N2 would be rerouted back along Wisconsin Avenue, Tenley Circle, and Nebraska Avenue beginning on January 22, 2012. This gave Wesley Heights and Glover Park residents access to Tenleytown–AU station as the September 2011 reroute abruptly taken away service to Tenleytown.[12][13]

In September 2015, WMATA proposed to eliminate all N3 service and replace it with the N4 due to low ridership and other services covering the route. Riders can ride the N4 up to 20th Street and transfer to the H1, L1 or S1 to Potomac Park/Foggy Bottom–GWU station and routes 30N, 30S, 32, 33, and 36 to Federal Triangle.[14]

On June 26, 2016, route N3 was eliminated and replaced by route N4. Select weekday peak hour N4 trips in the weekday peak hour direction were extended to Potomac Park along H Street and 18th Street (to Friendship Heights), I Street and 19th Street (to Potomac Park), and Virginia Avenue as well. Also routes N2, N4, and N6 terminus at Farragut Square were moved from the east side to the west side.[15][16]

On September 10, 2020 as part of WMATA's FY2022 budget, WMATA proposed to fully eliminate routes N2 and N4 and instead operate the N6 daily in order to simplify the line and low federal funds.[17] Routes N2 and N4 have not operated since March 13, 2020 due to Metro's response to the COVID-19 pandemic being replaced full time by route N6.[18]
