Volunteer fire fighters from Henrietta and Jolly responded to a grass fire on Hwy. 287, three miles west of Henrietta Friday afternoon.
The fire began in the median between the north and southbound lanes of the highway at about 2:15 p.m., and spread rapidly to a heavily wooded area on the south side of the road.
Southbound traffic was stopped for a short time as smoke obscured visibility, and was limited to one lane until the fire was put out.
The fire burned between five and seven acres before crews were able to extinguish the flames. At the time of the blaze, the temperature was 102 degrees with winds out of the north at 15 miles per hour.
Clay County is in a 30-day burn ban as drought conditions worsen.
