A settlement has been reached in a lawsuit that said dust from a western Nebraska ranch helped cause an interstate pileup that killed three people.

The families of two Colorado women killed in the 2005 pileup on Interstate 80 sued the U-Cross Ranch in Lincoln County District Court. The lawsuit said the ranch did not take proper steps to prevent dust from blowing across the interstate and creating a driving hazard.

Authorities had said 54-year-old Jeanne Kerechanin and 46-year-old Pamela Hartman were killed on March 10, 2005, when the car they were in was rear-ended by a semi on I-80. The semi driver, 70-year-old John Latham of Springfield, also died in the crash.

Terms of the settlement have not been released.
