Articulated buses have been getting a lot of attention lately. WMATA has expanded their use, and prior to selecting a streetcar Arlington considered using them on Columbia Pike. But where do the long buses actually run?

Curious to answer that question, I set out to identify the routes where I’ve seen articulated buses. This map shows the effort so far, but it’s probably incomplete. I don’t have any actual data on this, only what I’ve noticed anecdotally, and what a few other people have told me.

Take a look, and use the comments to let me know what I’ve missed or gotten wrong.

List of routes shown as “most articulated”:

• 70 – Georgia Ave in DC
• Y series – Georgia Ave in MD
• S1 – 16th St
• X2 – H St
• J2 – East West Hwy / Old Georgetown Rd
• Z series – Colesville Rd (shown truncated on the map)

Routes shown as “occasionally articulated”:

• L2 – Connecticut Ave
• S2 – 16th St (S4 also shown on map, will be removed with next draft)
• C2 and C4 – University Blvd
• K6 – New Hampshire Ave
