Nads confirm.
Just throwing it out there:
The tunnel connecting Walter Reed and NIH is not quite operational yet.
"To help relieve congestion, and as one of the last remaining projects from the Base Realignment And Closure plan, a pedestrian tunnel is being built to allow foot traffic to cross directly under MD 355 without the worry of vehicle traffic or signals. Another tunnel, accessible through the mezzanine level of the metro and an elevator on the east side of MD 355 will allow commuters to avoid having to cross MD 355 as well."
