A New Bridge for the St. Croix River in Pictures

The August/September 2015 issue of Concrete Contractor features the St. Croix River Bridge construction project. Here is a collection of photos highlighting the construction of the extra-dosed, precast segmental bridge.

Aug 21, 2015

The St. Croix River marks the boundary between Minnesota and Wisconsin. It’s also designated as a National Scenic Riverway by the federal government and is managed by the National Park service. As such, the federal government manages the character of the river, including the bridges crossing over it. The existing steel lift-bridge was built in 1934, crossing the river at Stillwater, Minn. and is only a few feet above water. 

Click here to read the story behind this complex and interesting project.

Forty or so stakeholders (cities along the river, Dept. of Natural Resources, National Park Service, and others) had to agree on a structure that wasn’t too imposing, would have low impact on the landscape, and design appeal. They settled on an extra-dosed, precast segmental bridge. The extra-dosed part of the design refers to the inclusion of towers about one-quarter the height (approximately 67 feet), of those for a cable-stay bridge. The low-angle support cables together with the post-tension (PT) cables in the precast segments provide the support for the bridge. The new bridge will be an architecturally graceful structure approximately 150 feet above the water on the Wisconsin side and 110 feet on the Minnesota side.

[VIDEO] Special Report: St. Croix River Crossing Project
The new St. Croix River crossing between Minnesota and Wisconsin near Stillwater is an “extra-dosed precast segmental” structural concrete bridge. Shown here are the first three 180 ton segments on either side of the pier, held in place by post-tensioned tendons. The blue device is called a “segment lifter” and it also supports a working platform on the edge of the segment that iron-workers use to do the cable tensioning.
