Knife River Corp., an MDU Resources Group company, acquired Mt. Hood Rock, which provides construction aggregate in eastern Portland, Oregon.

Around the Portland area, Mt. Hood Rock serves cities such as Gresham, Troutdale, Happy Valley and Sandy. Mt. Hood Rock has about 20 years of reserves remaining, according to Knife River,

“Producing high-quality construction aggregates and enabling vertical integration are two of the cornerstones of Knife River’s business strategy,” says David Goodin, president and CEO of MDU Resources. “A third is expanding in growing markets it knows well, such as the Portland area. This acquisition will create efficiencies and allow for growth from Day 1.”

Adds David Barney, president and CEO of Knife River: “We welcome our new employees, and we are excited about our continued growth. We’re coming off a record earnings year, we had near-record backlog to start this year, and we have now completed our ninth acquisition in the past three years. I’m very optimistic about 2021 and beyond.”
