Noise/other impacts

  • Periodic pile driving for bridge falsework and Pier 13 located on the Wisc. bluff will occur through fall 2014 and winter 2015. Falsework is a series of temporary structures that support the bridge spans during construction until the bridge can support itself.
  • Construction crews are working overnight hours on the Minn. highway project and river bridge through fall 2014. Nighttime construction activities may change as work progresses.
Highway overnight work
  • Overnight work may occur in fall 2014, as needed, to ensure construction stays on schedule. The S. Frontage Road from slightly west of Oakgeren Ave to Osgood Ave has the potential for overnight work beginning in October. Activities would include excavation, backfilling, grading and hauling.
Bridge overnight work
  • Overnight hours are 5 p.m. to 3 a.m. Monday through Saturday.
  • Crews are tying steel reinforcement bar as part of bridge construction.
  • Crews do not anticipate hauling any materials by truck during the overnight hours.

On land in Wisconsin

  • Crews are grading the new WIS 64 road surface between the river bluff and County Road E. The WIS 35 overpass bridge over WIS 64 is complete. Visit the Wisconsin project site for more information.
  • Crews will begin clearing trees on the Wisconsin bluff beginning in mid-September to prepare for building the bridge abutment and Pier 13. Tree clearing will occur as needed through the fall and the width of removal is limited to no more than 10 ft. beyond each side of the bridge.

On water

Slow/no wake zone
Slow/no wake zone
  • Boaters:
    • Please respect the one-mile slow/no wake worker safety zone in the St. Croix River between Stillwater and Bayport. The narrowed channel near bridge construction will remain at 300 feet and be marked with buoys through fall 2016.
    • Stay clear of the orange buoys near the bridge piers. They mark the under-water electric utility line that will provide power to lift each pre-cast segments into place.
  • Work is underway on all five pier locations in the St. Croix River—8, 9, 10, 11 and 12. Pier 8 is the river pier closest to Minnesota land, while Pier 12 is closest to the Wisconsin shoreline. Crews are using a temporary causeway to access Pier 8 and barges/boats to access Piers 9, 10, 11 and 12.
    • As of mid-September, 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 construction is ongoing at Piers 8, 9 and 12 through the fall.
    • Work at Piers 10 and 11 will mostly pause for the remainder of 2014. Construction will start up again in 2015 when the crossbeam forms currently in place at Piers 8 and 9 move to Piers 10 and 11, respectively.
