River bridge segment lifters arrive on site this week

Wisconsin highway traffic impacts begin

April 29, 2015

STILLWATER, Minn. – The first pair of segment lifters will arrive at the bridge construction site this week. They will travel 33 miles by barge from the Grey Cloud Island casting yard near Cottage Grove, down the Mississippi River and up the St. Croix River to the project site.

The lifters will be assembled on top of Pier 8, closest to the Minnesota shoreline, and will be used to place segments on both sides of the pier to create the spans that will become the driving surface of the new river bridge. See "St. Croix Crossing Segment Placement Process" animation.

The assembly process will take several weeks to complete. Crews anticipate beginning to install river bridge segments in late spring 2015.

Wisconsin approach traffic impacts update
Wisconsin approach work traffic impacts begin this week:

  • Traffic is now single-lane in both directions on the existing WIS 35/64 on the north end of the project limits.
  • WIS 35 traffic will begin using the new bypass on Thursday, April 30.
  • On Monday, May 4, the south access to Andersen Scout Camp Road from WIS 35/64 will close to traffic until September 2015. The detour is Andersen Scout Camp Road north of 150th Avenue at the County V interchange. See detour map.

Other St. Croix Crossing bridge construction updates
Other St. Croix Crossing bridge construction updates include:

  • Yesterday, crews began installing typical pre-cast segments on the Minnesota approach. They are placing them at Pier 1, closest to Highway 95.
  • Work continues on the cast-in-place sections of the Minnesota approach. The final concrete pour for the cast-in-place section that will carry Highway 95 traffic to the river bridge is anticipated to occur in early May.
  • Pier tower construction continues at Piers 8 and 9. 
  • Crews are removing the crossbeam truss and falsework at Pier 9. Pier 9 supports will be installed at Pier 11 in May then work will be occurring at all five pier locations on the river.
  • Crews are prepping Pier 10 for crossbeam construction. The crossbeam truss was installed on April 23.
  • Yesterday, crews completed the third of three concrete pours for the Pier 12 crossbeam.
  • Pile driving continues on the Wisconsin bluff in preparation for Pier 13 construction in late spring.

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.

August public boat tours on sale May 1
Tickets for the August public boat tours go on sale Friday, May 1. Go to St. Croix Boat & Packet to make reservations. Tickets are still available for the May and July public boat tour dates. 

Other Wisconsin highway construction updates
Construction crews completed the WIS 35 bypass this week. They are also installing reinforcement bar on the new County Road E interchange bridge.

Looking ahead, crews will:

  • Pour concrete for the County Road E interchange bridge deck.
  • Dig out the area for the cattle pass and begin construction of the box culvert.
  • Continue grading for new WIS 35/County Road E.
  • Begin installing culvert pipe and storm sewer.

Minnesota highway construction update
This week, construction crews are:

  • Grading and placing asphalt for new pedestrian/bicycle trails on the north side of the Greeley Street/Oakgreen Avenue intersection and along the South Frontage Road between Osgood Avenue and just west of Oakgreen Avenue.
  • Paving the South Frontage Road west of Oakgreen Avenue.
  • Preparing most road surfaces for a final layer of asphalt.
  • Landscaping throughout the project area.

The majority of roadway paving within the project limits, as well as construction to complete business driveways and local road connections, will begin in May, weather permitting.

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

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.
