Firefighters made significant gains on the Kyburz Fire overnight. The 615-acre blaze is 80 percent contained.

The fire is burning on the north side of Highway 50 in the Eldorado National Forest.

While the highway is completely open, officials are urging motorists to drive slowly, and watch for fire personnel and debris on the road.

Crews will continue today to hold and improve line around the perimeter of the fire, and begin mop up operations. Steep terrain, multiple dead snags, and increasing winds are likely to present challenges to firefighters today.

The fire started early afternoon July 8 when a vehicle lost a tire and that sparked the fire.
