In January 2021, Washington, D.C., experienced significant shifts in pedestrian and vehicle movement due to major events like the Capitol Riots and the Presidential Inauguration, as analyzed using Mapbox's Movement data. The anticipated large crowds for the inauguration did not materialize because in-person attendance was heavily restricted, with authorities implementing extensive security measures that resulted in the National Mall's activity levels dropping to those comparable to the early pandemic lockdown. While overall city activity remained at about 40% of pre-pandemic levels, specific events like the Prayer March on September 26th and the Capitol Riots temporarily spiked activity back to previous norms. Road closures around the inauguration affected traffic patterns, with some areas like the Francis Scott Key Bridge seeing a brief return to normal traffic levels, though others like DuPont remained below pre-pandemic averages.
