JACKSONVILLE, Fla. — Some streets in Jacksonville remain closed Sunday morning due after a massive fire at a historic Downtown Jacksonville building Saturday evening.
The Jacksonville Fire and Rescue Department said the fire happened at Main Street and Union Street.
Union Street between North Main Street and Laura Street remains closed as of Sunday morning. There is still a fire crew on the scene.
As of Sunday morning, there is still structural concerns with the building. Authorities are worried parts of the building could collapse onto a nearby propane tank.
As a result, the city said Union Street at Main Street will continue to be closed for several days. For traffic coming into downtown east on Union Street, drivers should divert to Laura Street then go onto Beaver Street.
Drivers should avoid the area if possible to ease congestion.
When crews first arrived on scene after 5:30 p.m., they saw flames coming from the second floor of the building.

Shortly after they realized the fire was "well-advanced" and that "building stability was an issue," so they began working from the outside of the building.
The second floor of the roof ended up collapsing which made the walls of the building unstable.
During a press conference Saturday night, JRFD stated that more than 100 firefighters responded to the scene. It took a little over an hour to get the blaze under control, JFRD said.
The building was previously a funeral home and no one was inside during the fire.
Several buildings nearby were put in danger after the floor collapsed, according to JFRD. Crews are considered this a three-alarm fire. There were firefighters on the scene throughout the night to put out the remaining hotspots.
Due to the circumstances of the fire, the state Fire Marshal's Office will be handling the investigation.
As of Sunday morning, there are no reports of any injuries.
Mayor Lenny Curry Tweeted about the fire saying "I’ve been briefed by Jax Fire and Rescue on a fire downtown. Updates will be provided as we have clear and accurate information. Pray for our firefighters. "
