Update: Fire in Downtown Silver Spring Construction Site

Updated, 5:30 p.m.:

Construction crews were working on the site for a new medical building located at 1110 Spring Street when a fire erupted, said a fire and rescue official.

The materials that caught on fire were "installation material along with some wood used to sure up the trench," according to Oscar Garcia the Montgomery County Fire and Rescue spokesman.

The construction fire occurred in the rear exterior wall of the building—in a 50 ft. trench in the exterior—resulting in a road closure on Spring Street between Georgia Avenue and Colesville Street.

No reported injuries to the construction workers or firefighters, said Capt. Garcia. 

Original Post, 3:06 p.m.: 

At approximately 1:15 p.m., clouds of black smoke began obscuring the blue skies above the construction site at the corner of Cameron and Spring Street in downtown Silver Spring.

Within minutes, more than a dozen fire trucks, police cars and rescue vehicles had surrounded the site, blocking traffic for a one-block radius around the site of the incident.

According to Lt. Robert Carter of the Montgomery County Police Department, some shingles caught fire, causing a large volume of smoke.

"No one was injured and the fire department had the fire out in a matter of minutes," said Carter.

The smoke brought dozens of workers out to the sidewalks to see what was going on.

Davon Harrison, works in a nearby office building an was on his way out.

"When I came out for my lunch break, I could smell what I thought was burning rubber, and wanted to find out what was happening. I hope nothing else nearby catches fire," said Harrison.

As of 1:45 p.m. people watching the police and fire squads work began to return to their offices and homes.

Correction: In an earlier version of the story we wrote the fire was in the basement. It actually occurred in a 50 ft. trench in the back of the building.
