Segment lifters to be assembled on top of Pier 9

May 27, 2015

STILLWATER, Minn. – Construction crews have lifted into position the first pre-cast river bridge segments on both upstream sides of Pier 8, closest to the Minnesota shoreline.

Late last week, crews connected the segment positioned over water to the pier table. This week, they will connect the segment positioned over land to the pier table. A temporary causeway on the west side of the pier allows access by land.

They also will lift both initial downstream segments into place. Two side-by-side segments make up the driving surface of the new river bridge.

The public can watch segment placement at Pier 8 via the project webcam. Select the “Live Image View” tab to watch in real-time.

In addition, crews will install segment lifters on top of Pier 9 this week. Load testing is anticipated to begin next week. Some of the lifter assembly will occur at night.

There are 650 segments that make up the driving surface of the new river crossing. River bridge segments will be placed in 2015-16.

Other St. Croix Crossing bridge construction updates include:

  • Upstream and downstream pier tower construction continues at Piers 8 and 9.
  • Crews are placing reinforcement bar, or rebar, for the first of three sections of the Pier 10 crossbeam. The crossbeam connects the upstream and downstream columns at each pier location. The first crossbeam concrete pour is anticipated for mid-June. Two work shifts are occurring at Pier 10 for crossbeam construction.  
  • Crews anticipate starting to place rebar for the first of three sections of the Pier 11 crossbeam next week.
  • Crews are installing forms for pier table construction at Pier 12. They anticipate starting to place rebar for the bottom section of the westbound pier table next week.
  • Pile driving and temporary trestle construction continues on the Wisconsin bluff in preparation for Pier 13 construction in early summer.
  • Half of the first span that crosses over Highway 95 from Pier 1E for the Minnesota approach is complete. Next, crews will install segments at Pier 1W—next to Pier 1E—to build out that span over Highway 95. The first several segments are anticipated to be installed this week, weather permitting.
  • Work continues on the cast-in-place sections of the Minnesota approach.

Stay clear of St. Croix Crossing construction zones. This season will be the project’s busiest yet, with hundreds of crew members, vehicles and equipment navigating small construction sites. Good vantage points to safely view construction are the Scenic Overlook and the Beach Road bridge west of the project’s on-site casting yard.

Wisconsin highway construction update

This week, construction crews are:

  • Grading on the north side of WIS 64/35.
  • Installing storm sewer.
  • Pouring concrete for the parapets—protective barriers along the sides of the bridge—of the new County Road E interchange bridge.
  • Pouring concrete for the walls and roof of the cattle pass.
  • Backfilling around the pedestrian tunnel.
  • Grading and placing an aggregate base on the new roundabouts.

Looking ahead, crews will:

  • Finish pouring concrete for the new County Road E interchange bridge and the cattle pass.
  • Continue grading for the new WIS 35/County Road E and WIS 64.
  • Continue installing storm sewer.
  • Continue placing an aggregate base on the new roundabouts.
  • Prepare and start placing concrete for the new WIS 35/County Road E roadway.

Minnesota highway construction update

This week, construction crews are:

  • Placing the final layer of asphalt on roads throughout the project work zone and painting permanent markings on the pavement—called striping. These activities will continue into early June.
  • Completing business driveways, including concrete curb where required. All business driveways will be complete by the end of June.
  • Finishing trails construction throughout the project area. This activity is anticipated to be complete by early June.
  • Working on landscaping restoration throughout the project area, including permanent seeding and sodding. Restoration activities will be complete by the end of June.

Intermittent lane and shoulder closures within the construction zone will occur through June to complete final roadway activities.

Next week, night work is scheduled to occur between 7 p.m. and 5 a.m. for crews to complete final paving activities on Highway 36 between Osgood Avenue and the Beach Road bridge. More information will be posted on the project website once available.

Minnesota approach work will be complete in summer 2015 and the new St. Croix Crossing bridge will open to traffic in fall 2016. When all work 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.
