AMERICAN FALLS, Idaho – The Bureau of Reclamation will temporarily close one of the westbound lanes on Highway 39 over American Falls Dam, beginning Monday, July 10 through Friday, Sept. 1.

Traffic will be restricted to the outermost lane across the dam while crews perform maintenance. This lane closure will be in place Monday through Friday from 6 a.m. to 6 p.m. until Sept. 1.

Wide-load vehicles are prohibited from crossing the dam during the specific work hours. Such vehicles traveling westbound should seek alternate routes or travel outside the posted work hours.

“We apologize for the delays this may cause,” said Keith Brooks, civil engineer with the Upper Snake Field Office. “Our crews will be working steadily through the summer to complete the work and re-open the inside lane.”

American Falls Dam was originally completed in 1928. The dam is part of the Minidoka Project and is located on the Snake River near American Falls. In 1978, the dam was reconstructed and replaced under the authority of Reclamation’s Safety of Dams Act.
