Bureau of Land Management and other crews worked a brush fire Friday afternoon on the north side of Warm Springs Avenue and Idaho 21 east of Boise.
Active flames were knocked down, the BLM said, and the fire was declared contained at about 8:30 p.m. Officials said BLM resources would stay overnight and into Saturday to mop up and check for hot spots.
The fire was estimated at 50 acres. It appeared that the fire had made its way onto Hammer Flat.
Idaho 21 was closed from Warm Springs to Sandy Point, but was later reopened.
BLM Fire Information Officer Mallory Eils said crews from the BLM, Forest Service, Boise, Meridian and Eagle collaborated to fight the fire.
Boise had provided structure protection for three residences and an outbuilding.
BLM was investigating the cause.
