If you need to get to Reagan National Airport next Tuesday between 11 a.m. and noon, here’s some advice: Don’t drive.

The Ronald Reagan Presidential Foundation will be unveiling a statue of the 40th president in front of Terminal A on Tuesday, and as a result traffic will be detoured and congested.

The closures will slow drivers heading towards the departure and arrival ramps for all terminals. Three lanes will be closed between 11 a.m. and noon, leaving just one lane open. There will be a detour around the event.

Here’s a map courtesy of the Metropolitan Washington Airports Authority, which operates Reagan and Dulles International Airport.

Travelers should consider taking Metrorail to and from the airport. If you are flying into National and can’t take the Metro home, use a cab instead of having someone come pick you up.

All lanes will remain open on the road next to the parking garages. Another suggestion, courtesy of airports officials, is to have drivers drop off or pick up passengers in the hourly parking garage nearest to your terminal.
