The National Park Service and the Federal Highway Administration will perform maintenance and safety improvements to two bridges that connect Ronald Reagan Washington National Airport to the George Washington Memorial Parkway. During the approximately nine month project, significant work will be performed on the Route 233 bridge, which connects Crystal City to the airport and the southbound Parkway ramp from the airport. Drivers should expect lane closures and detours as the work is performed.

Single lane closures will begin on September 10 and 11 from 9:30 a.m. to 2:30 p.m. on the Route 233 bridge and continue for the duration of the project. 

At least one lane will remain open to traffic on the Route 233 bridge and on the ramp from the airport to GW Parkway, except during one weekend of construction.

In addition to directional signage, Airports Authority Police and Park Service Police will be present to assist in directing drivers through the area and to minimize the traffic impact in the construction zone. 

The Park Service and Federal Highway Administration bridge construction project will allow for better access to and from the airport and add safety improvements to sidewalks and trails for pedestrians.
