Fire crews say they have contained, and put out a small brush fire near old Highway 395 near Eastlake Blvd. in Washoe Valley. One southbound lane is closed while crews mop up.

The Old 395 Fire was first reported just after 11:30 a.m. on Thursday. 

Crews with the Truckee Meadows Fire Protection District responded along with the Nevada Division of Forestry. 

Crews fully contained the fire at three acres.

Authorities tell us on-scene construction equipment helped put out fire, and that the fire may have been started by a construction crew, although an official investigation remains underway. 

There's no immediate word on how the fire started.
