Current construction impacts

On land in Minnesota

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 July.
  • Temporary shoulder closures are possible during this time.

Weigh-in-motion

  • Construction begins the week of July 13 through August.
  • Lane and shoulder closures on westbound Hwy 36 west of Osgood Ave. will occur to install weigh-in-motion loops under the pavement.
  • The exit ramp from westbound Hwy 36 to Hwy 5 will be 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 Highway 36.
