I-39 NB (WIS 78 to Marquette County Line), I-39 NB (northbound) lanes only - Columbia County

Project overview

The Wisconsin Department of Transportation (WisDOT) is developing final plans for concrete repairs on I-39 NB (northbound). This section of I-39 in Columbia County begins at the WIS 78 Interchange and continues north approximately 11 miles to the Marquette County Line.

Improvements include:

  • Repairs to the concrete pavement on the NB (northbound) lanes.
  • SB (southbound) lanes were repaired in 2014, and no work is anticipated for the SB lanes.
  • Asphalt shoulder repairs along I-39 north of US 51.
  • Investigation of the NB and SB ramps at the intersections of I-39 and WIS 33 will be conducted.
    • As well as the NB and SB ramps at the intersections of US 51 and I-39 north of Portage.


2024 - Construction anticipated



Traffic impacts/detours

Traffic will be restricted to one lane during the concrete pavement and shoulder repairs. Lane closure hours will be restricted on weekends during the summer months.
