ALBUQUERQUE, N.M. (AP) — A federal judge on Tuesday rejected a request by Native American tribes and environmentalists to stop work on a $10 billion transmission line being built through a remote southeastern Arizona valley that will carry wind-generated electricity from New Mexico to customers as far away as California.

The project — approved in 2015 following a lengthy review — has been touted as the biggest U.S. electricity infrastructure undertaking since the Hoover Dam was built in the 1930s.

Two tribes joined with archaeologists and environmentalists in filing a lawsuit in January, accusing the U.S. Interior Department and Bureau of Land Management of refusing for nearly 15 years to recognize “overwhelming evidence of the cultural significance” of the remote San Pedro Valley to Native American tribes including the Tohono O’odham, Hopi, Zuni and San Carlos Apache Tribe.
