Weather permitting, a single controlled blast is planned for WEDNESDAY, AUGUST 23, between 11:30 AM and 12:30 PM.
A warning siren will sound approximately five minutes before the blast and traffic on MD 355 (Rockville Pike) will be halted in both directions for ten minutes between Jones Bridge Road and South Wood Drive (at the Navy’s South Gate.
It is anticipated that minimal blast vibrations or noise from the warning siren may be detected by people within the immediate vicinity of the blast site.
This work is part of the ongoing construction of the Crossing Project at the Medical Center Metro Station, which will establish a shallow pedestrian underpass between NIH and Naval Support Activity Bethesda/Walter Reed National Military Medical Center, and deep elevators on the Navy side of MD 355 to the Metrorail mezzanine. Construction of the Crossing Project is anticipated through 2021.
Please note that the area of Rockville Pike near the Medical Center Metro Station, NIH and NSAB/Walter Reed is a construction zone. Please pay attention to all signs, and drive, walk or bike carefully through the area.
