Firefighters on Maui battled a brush fire that scorched 50 acres in Kahikinui near Piilani Highway Sunday, then flared up today to burn 40 more acres.

Firefighters were keeping the brush fire contained to the makai side of Piilani Highway and had closed the highway near Auwahi Windmills and Manawainui Bridge.

At 3:30 p.m. Sunday, firefighters responded to multiple calls from motorists who observed a rapid-spreading fire while they drove the back way out from Hana.

Firefighters arrived and found a large area of brush burning on the makai side of the highway, between mileposts 27 and 28, the same area where a brush fire burned approximately 6,000 acres in February, according to a news release from the Maui Fire Department.

No structures were threatened and no injuries were reported.

Fire crews fully contained the fire to the makai side of the highway at about 6:30 p.m. Sunday. Firefighters, along with helicopter crews making water drops, responded at 11:11 a.m. today to the flareup.
