Metro plans to rename its bus routes for the first time in 50 years, using responses to an online survey open until Sept. 28.

The current naming system, which Metro calls “outdated,” has been in place since the agency took over the region’s bus companies and streetcars in 1973.

“Trying to figure out the various Metrobus routes can be a puzzle with a mix of letters, numbers, and street names, express or limited-stop service,” Metro said in a statement.

Compared to other major metropolitan regions, the naming system can seem confusing and inconsistent for riders. Route names for Metrobus include numbers, like lines 42 and 62, as well as letters before numbers, such as the L2 and H2. Some routes reverse that and have numbers before letters, like 30N.

The names are not entirely random and do follow a set of rules (sort of). For example, routes with numbers before letters are often (but not always) based in Virginia. Routes with letters followed by numbers tend to be in D.C. and Maryland. Bus routes with just numbers are radial or hub lines in the District, linking to a central point. Routes for radial lines in D.C. are distinguished by names with just numbers, but confusingly, others are just letters.

The survey prompts respondents to offer feedback on new route name ideas, which include naming routes to reflect major streets or states they serve, or reflecting how often the bus arrives at each stop.

“Our region needs more consistency across all facets of bus stop design including signage and real-time information, accessibility, lighting and other safety elements, plus modernized shelters, seating, and other amenities,” Metro’s General Manager and CEO Randy Clarke said in a statement. “Engaging and collaborating as a region will help make a better transportation system for us all.”

The new naming system is part of Better Bus, a larger initiative by Metro to revamp its bus network. Earlier this year, Metro released maps for the reimagined network, which includes new routes, more frequency (20-minute frequencies for 100 routes) and 24-hour service. Metro is also partnering with agencies outside the District, such as Montgomery, Prince George’s, and Fairfax counties.

An initial network called “Year One” – using Metro’s current level of staffing and resources – will be implemented in 2024.
