U.S. Highway 93 about 5 miles south of Shoshone was back open Monday evening - but that drivers should expect delays - after being closed in both directions because of a fast-moving brush fire.

The Bureau of Land Management said the lightning-caused Antelope Fire - estimated at 10,000 acres Monday night - had been fueled by 25 mph wind gusts earlier in the day.

Seven air tankers are dropping retardant on the fire. Other resources battling the blaze include 8 engines, one dozer and four overhead.

The fire was started by lightning Sunday.

Some structures in the area are threatened by the fire.

Just before 3 p.m. Monday, the BLM tweeted that eastbound Highway 24 from Shoshone to mile marker 250 was also closed because of the Antelope Fire. The highway was reopened as of around 5 p.m., the BLM said in a tweet.

There are no estimates on when the fire will be contained or controlled.

The BLM is urging people to avoid the area. Fire behavior has been erratic.

KTVB / KTFT is off the air in the Twin Falls and Ketchum areas. CableOne says several power poles and a fiber line have been damaged in the fire interrupting television and internet service for some customers. Technicians are working to get to the area to get the problem fixed.
