The bridge on I-85 northbound just south of Ga. 400 near Piedmont Road collapsed about 7 p.m., Atlanta fire spokesman Sgt. Cortez Stafford said.
As of 10:25 p.m. Thursday, Stafford said a cause of the fire can’t be determined because inspectors can't get under the bridge due to structural concerns.
"The entire bridge is compromised," Stafford said. "Right now, it's still dangerous to go under there."
