On Sunday, August 11th, there will be a brief detour for all traffic using roadways in front of Terminals A, B and C at Ronald Reagan Washington National Airport for approximately one half hour between 5:45 a.m. and 6:15 a.m.

During this time, a helicopter will be moving a radar dome from atop the Air Traffic Control Tower at Reagan National Airport across the airfield to a new location for future installation. In addition, a cover for the tower roof will be moved in place via helicopter after the dome has been relocated. The two helicopter lifts are expected to take approximately 30 minutes.

In order to minimize inconvenience to passengers, the move has been scheduled for early Sunday morning when there is minimal flight activity. Passengers and those meeting them or bringing them to the airport should be aware of the following detour information

• • All traffic will be detoured from the roadways in front of Terminals A, B and C to the roadway which passes in front of the parking garages. Both the upper and lower roadways in front of Terminal B and C and the roadway in front of Terminal A will be temporarily closed.
  • The pedestrian bridges from the Metro station and Parking Garages B and C will remain open, and passengers may walk to the terminals from those bridges. Likewise, the pedestrian tunnel connecting Garage A to Terminal A will remain open.
  • Motorists dropping passengers off for airlines located in Terminal B or C may either drop them off in front of the garages by the bus shelters or drive into the garages and exit for free within 20 minutes.
  • US Airways passengers and employees may be asked to move from certain ticket counter and baggage claim areas during this ½ hour period.
  • All aircraft operations at the airport will be stopped for this activity.

The planned relocation could be cancelled if weather conditions are not appropriate.
