St Croix Crossing Pier 9 tower construction complete this week

Aug. 13, 2015

Multiple milestone concrete pours throughout project site represent progress

STILLWATER, Minn. – Construction crews will complete the final concrete pour for the westbound Pier 9 tower on Saturday, Aug. 15, marking the completion of pier tower construction at this pier location on the St. Croix River. Crews completed the eastbound Pier 9 tower on Aug. 5. Both pier towers at Pier 8, closest to the Minnesota shoreline, are also complete.

The contractor anticipates completing other milestone concrete pours this week, as well:

  • Crews will complete the second of three concrete pours for the Pier 10 crossbeam.
  • Crews will complete the first concrete pour for the eastbound Pier 12 tower, closest to the Wisconsin shoreline.
  • Crews will pour the top section of the west pier table at Pier 12.

Other St. Croix Crossing bridge construction highlights

  • Crews will begin installing the first stay cables at both Piers 8 and 9 the week of Aug. 24.
  • Crews are placing reinforcement bar, or rebar, for the second of three sections of the Pier 11 crossbeam.
  • Crews are excavating for the Pier 13 foundation footings on the Wisconsin bluff. They will begin driving foundation piling the week of Aug. 24.
  • Crews are removing the falsework that supported construction of one half of the cast-in-place eastbound Highway 95 Minnesota approach ramp.
  • Crews are installing falsework for the cast-in-place section of the eastbound Highway 36 Minnesota approach bridge.
  • Crews are placing the final deck surface for the cast-in-place section of the westbound Highway 36 Minnesota approach bridge. This process is ongoing through mid-Sept.
  • Crews will begin installing pre-cast approach segments at Pier 2E on Minnesota land the week of Aug. 17. This pier location is east of Pier 1.
  • Crews will complete construction of the new westbound Highway 36 Minnesota approach span between the west bridge abutment and Pier 1W next week. They will fill a four-foot gap between the completed spans with rebar and concrete, called a closure pour.

Wisconsin approach work highlights

The contractor continues to excavate the old County Road E, grade on the north end of the project for the new WIS 35/64, and place rock and gravel on the new alignment for WIS 64.

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.
