The Pylons and Cables

The claim has been made that the north and south 6th St. Viaduct bridges are the first cable stayed bridges in Wisconsin.

Not so, at least, according to the Wisconsin DOT. Wis DOT says the first cable stayed bridge in the United States is a cable stayed pedestrian bridge in Menomonee Falls, Waukesha County, Wisconsin.

The pylons are 142' tall.
