FONTANA, Calif. (KABC) -- A brush fire at the border of Riverside and Fontana has burned 35 acres and is 40% contained as of Wednesday evening, according to the Riverside County Fire Department.

The Oak Fire was burning near the Oak Quarry Golf Course on Sierra Avenue in Jurupa Valley, according to the fire department.

Firefighters in the Inland Empire are battling two brush fires that merged in the Fontana area Wednesday afternoon.

Officials say the forward rate of spread of the fire has been stopped.

Firefighting helicopters were taking water from the golf course to fight the fire, which sat at the border of San Bernardino and Riverside counties.

An evacuation order was issued for Alder Avenue south of Jurupa Avenue on the San Bernardino County side, but fire officials later lifted all evacuation orders and warnings just before 7 p.m.

There was no immediate word on what might have triggered the fires.
