AUSTIN (KXAN) — Multiple crews responded to a fire at a business on US 183 early Saturday in northwest Austin, according to the Austin Fire Department.

The fire is now out, AFD said, and one firefighter was treated for minor injuries.

The southbound US 183 frontage road lanes were closed while crews fight the fire, but have since reopened, an Austin Fire Department commander said.

Austin police called the fire into AFD around 6:30 a.m. Saturday while at a separate call nearby, AFD said. Crews found smoke coming from the building, and the fire was later upgraded to a two-alarm fire.

The fire was at a former Kerbey Lane Cafe location that is now an auto shop.

The fire department said the fire’s cause is under investigation.
