Murfreesboro Fire & Rescue Department's Districts 1 and 9 and Rescue 2 responded to a fire call at 1023 Bridge Avenue (City Auto Sales) just after 10:30 Tuesday night.

When crews arrived on scene, a 30'x60' metal shop was fully involved with heavy smoke venting through the B-side (lefthand side) of the structure.

According to Shift Commander Dale Maynard, the fire vented itself through four or five areas that appeared to have been previously covered with either plastic or fiberglass. "We are unsure if those areas were meant to act as vents for the shop or not, but they sure did help firefighters by letting a lot of the heavy smoke exit the building," he said.

Crews were able to make entry to the building and knock a majority of the fire down. "Once they were able to open the big bay door, the fire was easy to knock down," said Maynard.

No one was at the shop at the time of the fire. One vehicle that was inside the building was also damaged in the blaze.

Murfreesboro Electric Department was called to the scene to pull the electric meter.

A representative from City Auto Sales said the building was used to check the electric functions on vehicles before taking them to auction.

City Auto Sales' main building was not affected and will remain open for business.

The cause of the fire is unknown at this time. The Fire Marshal's Office will conduct a routine investigation.
