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 were expected to complete Pier 12 south this week, weather permitting.
Bridge foundations work in the St. Croix River is on track to be complete by early 2014.
All lanes of WIS 64 are open between 150th Avenue and County V. Crews have completed hauling clean material — composed of rock, sand and mud — from the St. Croix River bottom. This week they have been returning the top soil to the land and finishing landscaping.
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. The old bridge has been demolished, and clean-up from the demolition was scheduled to be complete this week, 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 is expected to re-open sometime next week, 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
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.
