MCAA Construction at NSA Bethesda

Over the next several years, Walter Reed National Military Medical Center will undergo a significant transformation as they replace outdated portions of the facility while remaining fully functional and continuing to provide safe, quality care. The Medical Center Additions and Alterations (MCAA) project is a multi-phased plan involving substantial renovations to two buildings and replacing nearly a third of the medical center with two new buildings.

MCAA-Related Advisories:

11JUN21: GATE OPERATIONS: To accommodate increased construction traffic tied to the MCAA project at WRNMMC, the following adjustments to NSA Bethesda gate hours will take effect Monday, June 28, 2021:

GATE 2 - Open Monday through Friday, 5 to 8 a.m., for inbound and outbound vehicle traffic. Open 1 to 6 p.m. for outbound traffic only. ADA Gate follows vehicle access hours. Pedestrian turnstiles remain accessible, open 24/7. 
GATE 5 - Open Monday through Friday as follows:
- 5 a.m. to 2 p.m. - Inbound commercial vehicles only
- 2 to 6 p.m. - Inbound and outbound vehicle traffic*
- 6 p.m. to 5 a.m. - As Needed: Inbound commercial vehicles only as necessary to support construction operations

*If commercial vehicle traffic is too heavy to facilitate outbound traffic, the NSA Bethesda Security Watch Commander may delay opening outbound lanes.

Overall Impact:

Noise: As of July 2021, the MCAA is not expected to create significant noticeable, continuous, or excessive noise.

Light Pollution: As of July 2021, the MCAA-related construction lighting is not expected to create disruptive light pollution.
