First Test Blast for MD 355 Crossing Project scheduled for Wed. July 19, between 10:00 and 11:00 AM

Please note that the first controlled test blast for the MD 355/Rockville Pike Crossing Project at the Medical Center Metro Station is scheduled for Wednesday, July 19, between 10:00 and 11:00 AM.

Traffic on MD 355 will be halted between Jones Bridge Road and South Wood Drive approximately ten minutes prior to the single blast, and alarms will sound five minutes prior to the blast. Roads will re-open shortly after the blast and an ” All Clear” horn has sounded.

Alarms will be heard, and minimal blast vibrations may be felt, by people in the immediate vicinity of the blast.

Controlled blasting will be used for the excavation of a deep elevator shaft on the Navy side of Rockville Pike that will connect to the Metrorail mezzanine.  The Crossing Project will also include a shallow pedestrian tunnel beneath Rockville Pike to provide safe and efficient crossing for bus and carpool riders and neighborhood pedestrians and bicyclists.
