Current construction impacts

On land in Minnesota


  • Motorists continue to experience single-lane traffic on Hwy 36 from Hwy 95 to the Washington Ave/Norell Ave intersection through November 2014.
  • The S. Frontage Road between Osgood Ave and Club Tara is closed to through traffic until early-July 2014. Local access for businesses and residents will always be available from the west using Osgood Ave OR the east using Stagecoach Trail - detour route map (PDF 0.5 MB).
  • Motorists continue to experience single-lane traffic on Hwy 95 between Hwy 36 and the north entrance to Sunnyside Marina.
  • Access to the north entrance of Sunnyside Marina is closed April 15 through April 18, weather permitting, for crews to complete utility work. During this closure, Sunnyside residents and marina users should use the south driveway entrance off Hwy 95 (see map PDF 2.6 MB). When it reopens, the north driveway will be in gravel conditions through mid-summer.
  • Access to businesses and residences along Hwy 36 and Hwy 95 will remain open at all times.


  • Oak Park Heights and Stillwater residents will hear repeated banging noises due to pile driving work for the pier foundations on the Minnesota shore (Piers 1-7). This work will occur Monday-Saturday 7 a.m. to 7 p.m. through May 2014, weather permitting.
  • Additional pile driving for the bridge falsework will continue into the summer. Falsework is a series of temporary structures that support the bridge spans during construction, until the bridge can support itself. Pile driving also will be occurring on the Wisconsin side of the river at some point during the 2014 construction season, to construct the pier on Wisconsin land.
  • Land preparation at the Oakgreen Ave/Greeley St intersection and on Hwy 95 north of Hwy 36 is ongoing through the end of April. Work involves clearing trees and shrubs.

On land in Wisconsin

In 2014, crews will grade the new WIS 64 road surface between the river bluff and County Road E. They will also construct the WIS 35 overpass over WIS 64, which requires a detour through July. View detour route (PDF 1 MB). Visit the Wisconsin project site for more information.

Slow/no wake zone

  • Work is underway on Pier 8 and Pier 9—the two river piers closest to the Minnesota shoreline.
  • Crews are using a temporary causeway to access Pier 8 and barges/boats to access Pier 9.
  • When ice is cleared from the river, watch for the narrowed channel to return. The narrowest point near bridge construction will be 300 feet wide. The channel will be marked with buoys through fall 2016.
  • Boaters – Please respect the slow/no wake zone in the restricted St. Croix River channel between Stillwater and Bayport.
