The Wisconsin Avenue Line, designated as Routes 31 or 33, is a daily bus route operated by the Washington Metropolitan Area Transit Authority. Its main purpose is to provide service to the upper Northwest side via Wisconsin Avenue NW.

Routes 31 and 33 operate between the Friendship Heights station of the Red Line of the Washington Metro and Potomac Park (31) or Washington Union Station (33), running every 10 to 12 minutes between 7 a.m. and 9 p.m. on weekdays. In addition, Route 33 operates on weekends every 10 minutes during the day and 15 - 20 minutes after 9 p.m. daily. Route 31 trips are roughly 45 minutes long, while Route 33 trips are 60 minutes long.

The routes operate out of WMATA's Western division, which uses New Flyer XD40 and XDE40 buses.

History

{{main|Pennsylvania Avenue Line (Washington, D.C.)}}

File:WMATA New Flyer XDE40 on Route 31.jpg

The 30 series line is one of the oldest transit routes in the city, tracing its origin to streetcar lines and the Washington and Georgetown Railroad in the 1860s. Buses began to operate on the line in 1936. Today, it is one of the most-ridden bus lines in D.C., serving more than 20,000 passengers a day in 2008.{{cite press release |title=Major improvements planned for Metro's most popular bus line |url=https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=1985 |date=February 14, 2008 |publisher=WMATA |accessdate=July 11, 2019}}

The five routes, 30, 32, 34, 35, and 36, begin their journey at Friendship Heights station and end at Potomac Avenue station (30), Southern Avenue station (32), or Naylor Road station (34, 35, and 36).

In 2008, WMATA launched a study on the Pennsylvania Avenue line to improve services and to reduce delays and bus bunchings.

=Route 31=

Route 31 was introduced on June 29, 2008, dubbed as a "neighborhood connector" as part of an overhaul of the busy Pennsylvania Avenue Line. Route 31 connects Friendship Heights station to Potomac Park to provide help to routes 32 and 36 along Wisconsin Avenue and replace routes 30, 34, and 35.{{cite press release |title=Metro launches major overhaul of 30s Metrobus line |url=https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=2157 |publisher=WMATA |date=June 26, 2008 |accessdate=July 11, 2019}}

=Route 33=

As part of proposals from 2013 to simplify the Wisconsin Avenue Line again,{{cite web |title=Improving bus service on the 30s line (Routes 31, 32, 34, and 36) |url=https://planitmetro.com/2013/09/05/improving-bus-service-on-the-30s-line-routes-31-32-34-and-36/ |accessdate=July 11, 2019}} route 33 was introduced on August 24, 2014 to replace the 32 and 36 portion along Wisconsin Avenue and to provide extra service to the 31, and the newly introduced Friendship Heights–Southeast Line or routes 30N and 30S. Route 33 provides more service between Friendship Heights station and Federal Triangle to help out the 30N, 30S, and 31. Routes 32 and 36 were shorten to Potomac Park being replaced by routes 30N, 30S, 31, and 33.{{cite press release |url=https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=5760|title=Metrobus service changes effective August 24 include more trips to improve reliability, reduce crowding |publisher=WMATA |date=August 15, 2014 |access-date=July 11, 2019}}{{cite web|url=https://www.wusa9.com/article/news/local/metrobus-service-changes-effective-august-24/65-285098694|title=Metrobus service changes effective August 24 |date=August 18, 2014 |website=WUSA |access-date=July 11, 2019}}

=Changes=

In 2019, as a part of WMATA's Blue/Orange/Silver Line Corridor Capacity & Reliability Study (BOS Study), the transit agency suggested, as one of six potential options, realigning Metrorail's Blue Line along Wisconsin Avenue, terminating at Friendship Heights or Bethesda station, after crossing over the Potomac River from Georgetown from Rosslyn.{{Cite web |last=Capriel |first=Jonathan |date=December 5, 2019 |title=Metro releases six concepts for the Rosslyn bottleneck.

On December 15, 2024, Route 31 was changed to operate during weekday peak hours only and Route 33 was rerouted to Washington Union Station via H Street/I Street and Massachusetts Avenue at all times.
