NASHVILLE, Tenn. (WKRN) – A portion of Gallatin Pike was closed early Wednesday morning as crews worked to contain a fire that sparked at a vacant building.

First responders were sent to the 4100 block of Gallatin Pike just before 2 a.m. for reports of a commercial fire. 

The Nashville Fire Department told News 2 that the abandoned building that caught fire used to be a flower shop and was surrounded by several businesses. 

At the scene, a News 2 crew saw fire personnel inside, outside and on top of the building to make sure that the fire was contained and would not rekindle. 

According to officials, firefighters had to use defensive tactics and an aerial truck to to extinguish the flames.

The fire department said the building caved in the center and Nashville Electric Service (NES) had to cut power to the establishment.

Gallatin Pike was closed for hours Wednesday morning as fire crews continued to investigate the scene. The roadway has since reopened.

The cause of the fire remains under investigation. No other information was immediately released.
