Highway 41 was closed from Highway 145 to road 200 due to the flames and smoke-- west of Millerton Lake.

The Madera County Sheriff's Office said the highway has re-opened.

The flames broke out at about 10:30 Thursday morning.

Highway 41 is closed from Highway 145 to Road 200 due to several small grass fires burning along the roadway.

The California Highway Patrol is investigating the cause but said the fire may have been sparked by a vehicle dragging a chain.
