A forest fire in Rockbridge County continues to grow.

The fire has burned 2,200 acres and it is expected to spread to 3,000 by Wednesday.

The U.S. Forest Service says the blaze has charred much of the James River face wilderness and has closed a section of the Appalachian Trail.

About 140 firefighters are building a fire line to contain the flames. They are hoping to have it 100 percent contained by Wednesday.

Four firefighters suffered minor injuries Monday, but no serious injuries have been reported in the fire, which was apparently sparked by lighting.

Forest officials are shuttling Appalachian Trail hikers around the blaze.

The terrain in this area is really steep and rocky and it is unsafe to put our firefighters in there. Forest officials say only 80 percent of the fire is contained.
