Golden Triangle reopened at about 3 p.m. Wednesday after the Denton Fire Department evacuated the building due to a gas leak.
The mall was evacuated around noon as a precaution because wind was pushing fumes into the building, the department said in a social media post.
A private contractor was doing work for Barnes and Noble outside the bookstore's main entrance and accidentally hit a 2-inch gas line, Battalion Chief David Boots said.
Atmos Energy crews arrived on scene and shut down the gas line at about 1:43 p.m., Boots said.
After crews sampled and tested the air inside the mall, workers determined it was safe to reopen.
