Big Island fire crews were continuing to work on a brush fire in Kailua-Kona Thursday that has burned about 400 acres.

The initial call came on Wednesday just before 3:30 p.m.  The fire was on open land surrounded by Queen Kaahumanu Highway, Hulikoa Drive, Hina Lani Housing and Hina Lani Street.

Fire officials said flames were spreading northeast but hard to contain because of the rough terrain and limited access.

At around 7:45 a.m. Thursday, the brush fire closed one lane on Queen Kaahumanu Highway.  It was reopened about 45 minutes later.

Damage was estimated at $40,000.

As of 4:30 p.m. Thursday, the fire was 100 percent contained.

There were no developed property or structures damaged.  The damage was contained to brush and pasture land.

Crews will be at the scene into the night to make sure the fire doesn't spread.
