Bridge foundations crews complete work to fill 40 caissons with concrete

All 40 caissons—also known as drilled shafts—that are part of the St. Croix Crossing bridge foundations are complete and filled with concrete. Caissons are 9-feet diameter steel casings that extend 90-120 feet below the river surface and create a solid foundation for the new bridge.

In addition, four of the 10 footings and four of the 10 columns are filled with concrete. All foundations work at Pier 9 north, Pier 9 south and Pier 12 north is complete. Crews will complete Pier 12 south the week of Nov. 11, weather permitting.

Bridge foundations work in the St. Croix River is on track to be complete by early 2014. Watch the progress of foundations construction on the project website, updated every Wednesday.

Wisconsin work

All lanes of WIS 64 are open between 150th Avenue and County V. Crews completed hauling clean material—composed of rock, sand and mud—from the St. Croix River bottom. They will return the top soil to the land and finish landscaping during the week of Nov. 11.

Grading is complete for the new access trail next to WIS 64 near the site of the new St. Croix Crossing bridge. Crews are installing storm water drainage systems further down the bluff. In spring 2014, crews will plant hundreds of tree saplings in the cleared area.

Grading work for the WIS 64 approach to the St. Croix Crossing bridge will begin in spring 2014.  

Beach Road bridge

The new Beach Road bridge is on track to open by late November. Clean-up from the old Beach Road bridge demolition will be complete the week of Nov. 11, weather permitting.  

S. Frontage Road closure

The S. Frontage Road remains closed for about two-thirds mile between Phil’s Tara Hideaway and Stagecoach Trail while crews tie a water main. The road will reopen sometime the week of Nov. 18, weather permitting. Access from Peller/Penrose avenues to the S. Frontage Road is also closed.  Visit the project website to view a detour map.

Water main work at Lookout Trail/Sunnyside Condos

Lookout Trail and a road within the northern end of the Sunnyside Condos complex remain closed while crews complete water main work. Crews expect to pave and open both roads in mid-November, weather permitting.

More information on continued impacts, detours and other updates is available on the project website.

Project information

The Minnesota approach project will be complete by fall 2014. The new St. Croix Crossing bridge and Wisconsin approach project will be complete by fall 2016. When all work is finished, motorists will have smoother highway pavement surfaces, improved flow at intersections, an improved frontage road system in Oak Park Heights 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.
