Firefighters battling a 9,000-acre in northwestern Wisconsin have contained the massive blaze.

Department of Natural Resources spokesman Robert Manwell said Thursday the fire in Douglas and Bayfield counties is 100 percent contained. Manwell says fire crews will be handling small brush fires and reworking the lines that contain the wildfire.

Authorities opened all roads in the area overnight and some residents headed back to their homes. The fire, which began Tuesday, destroyed 17 homes and 30 other structures. The DNR says no one has been hurt in the largest forest fire to hit northern Wisconsin in 33 years.

Gov. Scott Walker has declared a state of emergency in Douglas and Bayfield counties, which makes the Wisconsin National Guard available for recovery efforts. The governor plans to tour the area Thursday.
