ZEBULON PIKE LOCK AND DAM
The eleventh of twenty-eight LOCKS and dams between St. Paul and Minneapolis, Minnesota, and St. Louis, Missouri, the locks cost $1,470,000 to construct. The dam, at 1,278 feet one of the largest on the river, helped maintain the nine-foot channel for river traffic.
The total cost of the project came to $7,443,000 with as many as 950 workers employed at the site at one time. Although it was announced that as many as four deaths could be expected on a project of this size, only two workers were killed. Harold Arendt fell to his death, and Ardenal Thompson was fatally struck on the head by a stern-operated clam shovel. (Photo Courtesy: Daniel Callahan)
