How to plan your trip near the Mall
Because detours change where buses run during late-night hours, riders should plan around the cross streets WMATA lists for those routes (not just the usual bus path). In particular, the detour work happens between midnight and 5 a.m., so commuters traveling late at night should double-check their route before leaving.
Also, MPD’s traffic advisory and NPS access rules can affect how you reach (or cross) the Mall area on foot during the event period.
