Stay cables go up at Pier 8
Sept. 16, 2015
Project adds a third webcam
STILLWATER, Minn. – The contractor has installed the first set of stay cables at Pier 8—closest to the Minnesota shoreline, reaching another milestone in St. Croix Crossing bridge construction.
An individual stay cable above the bridge’s driving surface consists of 76 strands bunched together. Crews string each strand by hand through a pipe that anchors to the pier tower on one end and a stay segment on the opposite end. Once the strands are installed, crews stress the cable from inside the bridge using a hydraulic jack. Eight stay cables will extend from each side of the river pier towers.
Crews will install stay cables and continue to place pre-cast river bridge segments at Piers 8 and 9 through the fall. The contractor also anticipates installing some pre-cast river bridge segments at Pier 12—closest to the Wisconsin shoreline—before the end of 2015.
New project webcam
The St. Croix Crossing project has installed a new webcam on top of Pier 8. The webcam captures four additional angles of construction at preset times. It provides users with close-up views of construction at Piers 8 and 9, as well as wide-angle views of Minnesota approach construction and the project’s on-site casting yard near the Highway 36/95 interchange. To access the new webcam, go to http://www.dot.state.mn.us/stcroixcrossing/webcam.html and select “Gigapixel Camera.”
Other St. Croix Crossing bridge construction highlights
- Crews anticipate completing all crossbeam construction on the St. Croix River in October. Crossbeam construction is complete at Piers 8, 9 and 12 and is in progress at Piers 10 and 11. The crossbeam connects the upstream and downstream pier columns at each pier location.
- Crews are removing the truss and other falsework that supported crossbeam construction at Pier 12, as well as constructing the towers at this pier location.
- Today crews will begin driving foundation piling for Pier 13, the single pier location on the Wisconsin bluff.
- Crews are placing pre-cast segments for the approach bridge deck at Pier 2E, east of Highway 95 in Minnesota.
Wisconsin approach work update
Beginning the week of Sept. 21, the contractor will switch traffic from the existing WIS 64 lanes on the north end of the project to the new westbound WIS 64 lanes. Traffic will remain this way until the new St. Croix Crossing opens to traffic in 2017.
In addition, the new alignment for WIS 35/County Road E and School Road will open to traffic in early October. At this time, the current County Road E detour will be removed.
The new St. Croix Crossing bridge will open to traffic in fall 2016. When the St. Croix Crossing project is finished, motorists will have smoother highway pavement surfaces, improved flow at intersections, an improved frontage road system—including safer access—and a new river crossing between Minnesota and Wisconsin. All of this will occur while maintaining or restoring the area’s cultural, historic and environmental resources.
