Highway History

These tow pairs of twin bridges on Interstate Route 90 in Wisconsin Illustrate both the functional grace and the diversity of design with which bridge builders fit structures to location needs. The girder bridges supported on piers cross the Wisconsin River; the steel arches span Mirror Lake near the Wisconsin Dells. These bridges are part of a 55-mile, $32 million section of Interstate 90 between Madison and the Dells, opened to traffic in October 1961.
