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. Photo taken by J.R. Manning in July 2008 |

The South Approach You have to be able to circumnavigate Milwaukee's first rotary intersection in order to use this bridge - a feat which many local motorists cannot seem to accomplish without a great deal of consternation. Photo taken by J.R. Manning in July 2008 |

The Entire Viaduct Looking South from the North viaduct. These mirror image structures replaced the 6th Viaduct, built in 1908, that stretched 2,780 feet across the valley. Ramps provided access to Canal Street and the US Post Office. Photo taken by J.R. Manning in July 2008 |
