St. Croix Crossing bridge deck construction underway in Minnesota and on the St. Croix River

First river bridge segment lifted into position on May 19

May 20, 2015

STILLWATER, Minn. – The first pre-cast St. Croix Crossing bridge segment was lifted into position at Pier 8—closest to the Minnesota shoreline—yesterday. Crews will connect it to the pier table later this week. The public can watch segment placement at Pier 8 via the project webcam.

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 bridge construction updates include:

  • Crews are placing pre-cast segments for the Minnesota approach at Pier 1 next to Highway 95. These segments will become the driving surface of the approach spans. Half of the span that crosses over Highway 95 will be installed by the end of the week.
  • Work continues on the cast-in-place sections of the Minnesota approach.
  • Upstream and downstream pier tower construction continues at Piers 8 and 9.
  • Crews anticipate installing segment lifters on top of Pier 9 this week. The lifters will place segments that will become the driving surface of the new river bridge.
  • Crews are placing reinforcement bar for the first of three sections of the Pier 10 crossbeam. The crossbeam connects the upstream and downstream columns at each pier location.
  • Crews installed the crossbeam truss at Pier 11 yesterday.
  • Crews are installing forms for pier table construction at Pier 12.
  • Pile driving and temporary trestle construction continues on the Wisconsin bluff in preparation for Pier 13 construction this summer.

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:

  • Installing storm sewer around the east/west roundabout.
  • Pouring concrete for the parapets of the new County Road E interchange bridge. These are protective barriers along the sides of the bridge deck.
  • Grading the new WIS 64 north of County Road E.
  • Grading for the roundabout on WIS 35/Main Street.
  • Pouring concrete for the walls of the cattle pass.

Looking ahead, crews will:

  • Pour additional concrete for the walls of the cattle pass.
  • Finish pouring concrete for the parapets of the new County Road E interchange bridge.
  • Continue grading for the new WIS 35/County Road E and WIS 64.
  • Continue placing culvert pipe and storm sewer.
  • Start placing an aggregate base on the WIS 35 east roundabout and continue west on WIS 35.
  • Start placing gravel on the new roundabout and School Road.

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 within the project limits will be complete by the end of June.
  • Finishing trail construction throughout the project area. This is anticipated to be complete by early June.
  • Constructing medians and pedestrian ramps throughout the project area.

Intermittent lane and shoulder closures within the construction zone will occur through June to complete final roadway activities. However, all short-term lane closures as part of the Minnesota approach road work will be lifted Friday afternoon, May 22, through Monday, May 25, for the Memorial Day weekend.

Memorial Day weekend traffic impacts
Highway 36 and Highway 95 in the St. Croix Crossing project area will be open to traffic. Traffic will be single-lane in both directions between Highway 36 east of Osgood Avenue to Highway 95 and near the Highway 36/95 intersection. Construction crews will not be on site Saturday, May 23, through Monday, May 25.

A one-mile long, narrowed river channel and no wake zone are in place on the St. Croix River near bridge construction between Stillwater and Bayport. Boaters are asked to stay between the red and green buoys. Though construction on the river will pause for the holiday weekend, officials will patrol the bridge site area.

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.
