Wisconsin approach work traffic impacts to begin late April

Wisconsin approach work traffic impacts to begin late April

April 15, 2015

STILLWATER, Minn. – St. Croix Crossing Wisconsin approach work traffic impacts are anticipated to begin in late April, weather permitting.

  • Beginning the week of April 27, traffic will be switched to single-lane in both directions on the existing WIS 35/64 on the north end of the project limits.
  • On Monday, May 4, the south access to Anderson Scout Camp Road from WIS 35/64 is expected close to traffic until September 2015. The detour is Anderson Scout Camp Road north of 150th Avenue at the County V interchange.

Visit for more information and a detour map.

2015 Wisconsin approach work will include:

  • Grading from just north of County Road E to WIS 64.
  • Grading, paving and incidentals on the relocated County Road E.
  • Constructing the interchange structure at County Road E and the roundabouts at the new WIS 35/County Road E intersection and at the interchange location.

St. Croix Crossing bridge construction update

St. Croix Crossing bridge construction updates include:

  • Construction crews anticipate placing the first typical segments that will form the pre-cast bridge deck spans on the Minnesota approach next week. They will place segments at Pier 1, closest to Highway 95.
  • Pre-cast segment production continues at both project casting yards.
  • Work continues on the cast-in-place sections of the Minnesota approach spans.
  • Crews are removing the falsework and truss structures that supported crossbeam construction at Piers 8    and 9.
    • Crews are beginning to install Pier 8 supports at Pier 10.
    • Pier 9 supports will be installed at Pier 11 later in the month. At this point, work will be occurring at all five pier locations in the river.
  • The third of three sections of the Pier 12 crossbeam is now under construction.
  • Crews anticipate barging the first pair of segment lifters to the project site next week. The lifters will be assembled on top of Pier 8 and will be used to place river bridge segments that will become the bridge deck.
  • Upstream and downstream pier tower construction continues at Piers 8 and 9.
    • Crews have installed three of four cable stay boxes in the downstream tower at Pier 8. There are four cable stay boxes stacked on top of each other in each pier tower. Two cables will pass through each cable stay box and anchor to select segments that make up the bridge deck.
  • 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. A good vantage point to safely view construction, including segment installation on the Minnesota approach, is the Beach Road bridge west of the project’s on-site casting yard.

Other Wisconsin highway construction updates

This week, construction crews poured the wingwalls for the new County Road E interchange bridge. They also poured additional sections of the concrete walls of the pedestrian tunnel under the new WIS 35.

Next week, crews will complete the concrete work for the pedestrian tunnel.

Minnesota highway construction update

Construction crews are on site to complete Minnesota approach work. The following activities will occur in April:

  • Grading to prepare for the final layer of asphalt on most road surfaces within the project limits.
  • Trail construction.
  • Landscaping throughout the project area.

Asphalt placement, as well as construction to complete business driveways and local road connections, will begin in May, weather permitting.

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.
