1 firefighter injured in southeast Austin blaze, fire now under control

The Austin Fire Department is battling a three-alarm fire in south Austin with the building fully involved, the agency said on social media Wednesday.

AUSTIN (KXAN) -- One firefighter was injured after a three-alarm fire in south Austin that is now under control, the Austin Fire Department said. No civilians were injured.

The blaze started Wednesday afternoon, and AFD said over 120 firefighters were working to extinguish the fire.

At 2:20 p.m., AFD said crews responded to the three-story building with a "defensive" fire in the 2900 block of South Interstate 35 service road northbound, the agency said on social media. That's near Oltorf and Woodward Street.

AFD said there was a structural collapse on the second floor of the building with "multiple exposures," which means there is more danger associated with the fire.

Video, courtesy of @mikekingart, shared with KXAN showed large flames and plumes of black smoke breaking out from the top of the building.

In an update at 2:50 p.m., AFD said crews are searching the area for other possible fires due to the windy conditions.

Austin-Travis County EMS and Austin Transportation Public Works also responded to assist.

One northbound lane of the I-35 frontage road near Woodward Street is closed. Drivers are urged to avoid the area, as traffic will be impacted during this time.

Officials will continue investigating the damages and what caused the fire, AFD said.
