Wisconsin approach work to resume April 18

April 14, 2016

STILLWATER, Minn. – St. Croix Crossing construction crews are actively working at all five river pier locations. The contractor will focus on the following river bridge construction work and milestones in 2016.

  • Crews will place pre-cast concrete segments that make up the driving surface at all five river pier locations and at Pier 13 on the Wisconsin bluff. They will use ringer cranes (PDF) to place segments at Piers 10 and 11 and from Pier 13 to the east abutment in Wisconsin.
  • Crews anticipate meeting the bridge deck spans between Piers 8 and 9, closest to Minnesota land, this summer.
  • Crews anticipate completing segment placement at Pier 12, closest to Wisconsin land, before the end of the year.
  • Crews are now installing stay cables at Piers 8 and 9. They will also begin stay cable installation at Piers 10, 11 and 12 in 2016.
  • Crews anticipate completing segment production at both project casting yards by the end of the year.

River bridge construction highlights for the week of April 11 are:

  • Crews have finished stressing the fourth set of stay cables at Pier 9. Next, they will place the 18th and 19th segments in the bridge deck construction sequence.
  • Crews are placing the first eastbound and westbound segments at both Piers 10 and 11.
  • Crews will place the fifth segment in the bridge deck construction sequence at Pier 12 by the end of the week.
  • Crews are assembling one of two ringer cranes on a temporary pad adjacent to the Wisconsin shoreline. Once operational, this crane will place river bridge deck segments between Pier 13 and the east abutment in Wisconsin.

Wisconsin approach construction resumes April 18

Wisconsin approach construction is expected to resume on Monday, April 18. Initial work will include finishing the grading project that began in 2015. Once this work is complete, the project’s 2016 contractor, Trieweiler Construction & Supply Co., Inc., will begin concrete paving for the new WIS 64. The contractor anticipates completing the majority of the work in 2016. However, the seamless tie-in to the new river bridge will not occur until 2017 and the new four-lane WIS 64 will not open to the public until the new bridge opens to traffic in fall 2017. There will be no traffic impacts in 2016.

Construction crews continue to place approach bridge segments at Pier 2 that will make up the off-ramp to Highway 95 in Minnesota.
