House Approves Measure for Copper Road Through Alaska Wilderness

Highlights

The U.S. House passes vote on Ambler Access Project, a 211-mile road to Alaska’s proposed copper and zinc mine.
Environmental and tribal groups warn of risks to caribou migration, salmon habitats, and permafrost stability.
The $7.5 billion copper deposit is seen by supporters as vital for cars, electronics, and renewable energy.

The U.S. House of Representatives voted 215-210 to advance the Ambler Access Project, a proposed 211-mile road through Alaskan wilderness that would connect to a future copper and zinc mine.

The project has stirred debate for years. It was given a permit by the Trump administration in 2020, but the Biden administration later blocked it, citing risks to wildlife and Alaska Native communities that depend on caribou and salmon for food.

Supporters of the road, including many Alaska lawmakers, argue that it is vital to reach a copper deposit valued at about $7.5 billion.

Copper plays a bigger role in manufacturing cars, electronics, and renewable energy technologies like wind turbines.

Congressman Nick Begich III, who introduced the resolution, said Alaska’s future depends on using its natural resources rather than being restricted by federal rules. The measure passed mainly along party lines, with just one Republican joining Democrats in opposition.

Opponents, including environmental groups and Alaska Native organisations, warn that the road could disrupt the migratory path of caribou, contaminate salmon streams, and accelerate the melting of permafrost.

The Interior Department has raised concerns that thawing permafrost could cause landslides, flooding, and release gases that worsen climate change. Despite congressional backing, Senator Lisa Murkowski acknowledged that multiple challenges remain, meaning the project will not move forward immediately.
