Current construction impacts

On land in Minnesota

Current traffic impacts

  • Traffic remains single lane on the ramp between Hwy 36 and Hwy 95 through fall 2015.
  • All other roadways in the construction zone are fully open to traffic.

Upcoming activities

Beginning March 2015, weather permitting, crews will return to complete the Minnesota roadway portion of the St. Croix Crossing Project. While the majority of work was completed in 2014, there are still some activities to be completed in 2015. Here is an overview of the remaining work and an estimated schedule for completion:

Current construction area. Click map for larger PDF version.
Business driveways and local road connections (April-June)
  • Modifications to some business driveways and local road connections on the S. Frontage Road will occur, including final grading activities and placement of curb, gutter, and final layer of asphalt.
  • Business access will be available at all times.
  • Communications staff will contact businesses prior to the start of driveway work.
Road surfaces (May-June)
  • A final layer of asphalt will be placed on most road surfaces.
  • Permanent lines will be painted on the pavement – called striping.
Trails/landscaping (April-June)
  • All remaining trail and landscaping work.
Hwy 36/Hwy 95 ramp (Fall)
  • The ramp from Hwy 95 to westbound Hwy 36 will be constructed in fall 2015.

Noise/other impacts

  • Periodic pile driving for bridge falsework, the east bridge abutment and Pier 13 located on the Wisc. bluff will occur through spring 2015. Falsework is a series of temporary structures that support the bridge spans during construction until the bridge can support itself.
  • Night work is underway at Piers 8 and 9 in the St. Croix River.

On land in Wisconsin

  • Crews will clear trees as needed on the Wisc. bluff as part of east bridge abutment and Pier 13 construction. This will occur through spring 2015. The width of removal is limited to no more than 10 ft. beyond each side of the bridge.
  • Construction of a temporary trestle out to the site of Pier 13--including periodic pile driving--is ongoing through spring 2015.

On water

  • Work is ongoing at Piers 8 and 9 in the St. Croix River. Pier 8 is the river pier closest to Minnesota land. Crews are using a temporary causeway to access Pier 8 and barges/boats to access Pier 9.
    • All five river pier locations are built to the height of the crossbeam. The crossbeam connects the upstream and downstream columns at each pier location.
    • Crossbeam and pier table construction is complete at Piers 8 and 9.
    • Crews anticipate beginning to install river bridge segments in late spring 2015.
    • Work at Piers 10, 11 and 12—closest to Wisconsin land—will resume in spring 2015.
