History
Route 16Y began service on September 29, 2002, becoming the first bus route to run through Downtown D.C. since the opening of the Yellow Line in 1983. The 16Y was also created by WMATA to provide limited stop/ express service between the neighborhood of Barcroft and McPherson Square station via Columbia Pike, Arlington Boulevard, and the Roosevelt Bridge. The original 16Y route serves limited stops on Columbia Pike between South Four Mile Run Drive, and South Courthouse road, until it runs non stop to Downtown, serving all stops until McPherson Square station. The 16Y serves Farragut Square Station, both the North and the West side, before arriving to McPherson Square. The 16Y became part of the Pike Ride route in 2003, alongside with the other 16 lines. As part of the Pike Ride project, the 16Y brings in more faster service during rush hours through Columbia Pike. The 16Y became a MetroExtra route in 2012, alongside with route 16F of the Columbia Pike–Federal Triangle Line. This groups the 16Y, as an limited stop routes, while all other 16 lines are local routes which serves all stops in Columbia Pike. Alongside with the addition of MetroExtra Better Bus program, it brings more reliable service on the 16Y when more times was added throughout the years.
Starting on April 7, 2003, the 16Y added service to the Arlington CountyDepartment of Human Services /Sequoia at South Courthouse Road and 2nd Street South. This stop became a "Boarding Only" during morning peak periods, and "Boarding and Alighting Only" during afternoon peak periods. From the addition of the stop, the 16Y eliminated the alighting only stop at the neighborhood of Penrose on Columbia Pike, as the 16Y will no longer run onWashington Boulevard, south of Walter Reed Drive.
The 16Y began to add more service through South Courthouse Road. The 16Y started to serve on the intersection of 6th Street South to bring more stops to the route. As the DHS/Sequoia stop at 2nd Street South is a Boarding Only stop on morning peak period, this new stop allows access to DHS/Sequoia by walking.
The 16Y began to add service through Lyon Park and Fort Myer near Arlington Boulevard, by adding more stops to bring more service on the 16Y. The DHS/Sequoia stop is no longer a Boarding Only stop on morning peak hours, after service on Washington Boulevard and Arlington Boulevard was added. Alongside these changes, the 16Y now operates near Fort Myer on Arlington Boulevard and North Pershing Drive. Unlike its original timetable, this stop is both Boarding and Alighting during peak hours.
