BOISE, Idaho — Interior Secretary Sally Jewell has delayed indefinitely a final decision on two pathways for a new power line across southern Idaho.

The decision on the so-called Gateway West Transmission Line was announced Tuesday.

Jewell said the 990-mile power line stretching across Wyoming and Idaho remains a high priority for President Obama. She also said a new line will strengthen the nation's power grid and bring a more diversified portfolio of energy to the regional market.

But the proposed routes for the project remain controversial.

The U.S. Bureau of Land Management has identified two routes, but stretches of each have run into opposition.

One route has drawn fire for cutting too close to Kuna in Owyhee County; the other drawing criticism from officials in Cassia and Power counties.
