Parking Restrictions

DDOT wants to remind the public that in addition to previously announced road closures, parking restrictions will also be in place in various locations throughout the city. Some parking restrictions may not be security related but have been implemented in order to assist with traffic flow outside of the secure zone in an effort to decrease possible gridlock and delays. These include but are not limited to I Street between 11th and Pennsylvania Avenue and L Street between 11th and Pennsylvania Avenue in northwest. DDOT reminds motorists to be mindful of posted “Emergency No Parking” signs and to not park in posted areas as ticketing and towing will be enforced. Road closures and a map of restricted areas may be found on the DDOT website at

DC Circulator Rerouting (Please note a new route has been added since previous release*)

Passengers wishing to continue through will need to disembark the bus and walk to the other side of the Convention Center to connect to another Circulator bus. All other normal stops will remain the same. The turnaround for this route is as follows:

  • K Street (heading east)
  • Right ont11th Street NW
  • Right onto I Street NW
