Current traffic impacts

  • Traffic is single-lane in both directions on Hwy 95 north of the Hwy 36/95 intersection through fall 2015.
  • Traffic is single-lane on Hwy 36 between east of Osgood Ave and Hwy 95.

Minnesota road work clean-up

  • Minor Minnesota road work clean-up activities will occur through August.
  • Temporary shoulder closures are possible during this time.


  • Construction is underway through August.
  • The on-ramp from Hwy 5 to westbound Hwy 36 is temporarily narrowed to allow construction crews to widen the ramp.
    • Ramp widening provides law enforcement with a safe place to properly weigh commercial vehicles that trigger the weigh-in-motion loops on Hwy 36.

N. Frontage Road realignment near Osgood Ave

  • Construction will begin in July on the N. Frontage Road between Oren Ave and Osgood Ave and is anticipated to be complete in fall 2015. See map (PDF)

Wisconsin bluff construction activities

  • Work is occurring at all five piers in the St. Croix River. Crews are using a temporary causeway to access Pier 8 and barges/boats to access Piers 9-12. Pier 8 is the river pier closest to Minnesota land and Pier 12 is closest to Wisconsin land.
    • 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 complete at Piers 8, 9 and 12 and is in progress at Piers 10 and 11.
    • Pier table construction is complete at Piers 8 and 9 and is in progress at Pier 12.
