The History Channel website mentions Duluth today in its “This Day in History” feature, pointing out that Duluth Mayor Gary Doty cut the ribbon opening the 1,480-foot–long Leif Erickson Tunnel on Interstate 35 on Oct. 28, 1992.

“With the opening of the tunnel, that highway — which stretches 1,593 miles — was finished at last,” the article notes before delving into how the underground freeway idea replaced an earlier plan to put I-35 on stilts.

“This ‘cut-and-cover’ plan turned out to be a smashing success,” the story concludes, pointing out the “tunnel kept the disruption of the road to a minimum and provided city residents and tourists with an extremely pleasant place to go and relax.”
