Bus Priority

red bus lane in Washington DC

In 2019, almost as many District residents rode Metrobus as Metrorail each day. However, over the last decade, average bus speeds have declined. DDOT is working to improve bus travel speeds and reliability across the District through bus priority projects and program areas.
