Residents seeking an update on how the expansion of the National Naval Medical Center will affect their lives can get one Tuesday night at the monthly meeting of the Montgomery County BRAC Implementation Committee.

The expansion of the hospital is part of the 2005 Base Realignment and Closure (BRAC) plan. It is expected to create traffic headaches in the already congested area when the moves are completed in September.

At the meeting, the Maryland State Highway Administration will provide an update on its efforts to upgrade four intersections surrounding the hospital. The update should include the firmest time line yet for the projects, most of which will not be complete until late next year at the earliest.

Officials are also expected to discuss their strategy in applying for $300 million in federal funding that has been allocated for traffic improvements at military hospitals impacted by BRAC. The Department of Defense released guidelines for the application process last week.

Walter Reed Army Medical Center, the source of the National Naval Medical Center’s expansion, will hold a closing ceremony Wednesday. Patients and employees will transfer next month.

The public meeting will take place at 7:30 p.m. at the Bethesda-Chevy Chase Regional Services Center, 4805 Edgemoor Lane.
