PIERRE, South Dakota (AP) - The South Dakota stretch of Interstate 90 is being renamed as the "Purple Heart Trail."
The Purple Heart is a decoration given to wounded soldiers. The designation will apply to Interstate 90 in South Dakota from the Wyoming border to Minnesota.
South Dakota's Transportation Commission recently approved a request for the designation. Forty-five states have named parts of their highways as Purple Heart Trails.
Ceremonies are scheduled Tuesday at the Valley Springs rest area, near the South Dakota/Minnesota border, and the Spearfish rest area near South Dakota's border with Wyoming.
