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several years, Walter Reed National Military Medical Center will undergo a significant transformation as they replace outdated portions of the facility while remaining fully functional and continuing to provide safe, quality care.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:

22JUL21: NOISE - 1: The weekend of July 24-25, there may be construction-related noise coming from work being done on the Walter Reed Bethesda complex. The noise is not expected to be excessive, but may be audible in areas around and adjacent to the installation, including along Jones Bridge Road.

22JUL21: NOISE - 2: Concrete pouring operations at Walter Reed Bethesda are expected to begin mid-August, weather dependent. These overnight operations are expected to take place in 1-2 day increments, with each portion of the overall project taking place every 5-6 business days from August through October.

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.
