Project location

I-39 Bridge Replacement (Grotzke Road Bridge), Columbia County

Project overview

The proposed project will replace existing steel girder bridge carrying Grotzke Road over I-39 in Columbia County. It is anticipated that no additional right-of-way acquisition will be required on this project. 

Proposed improvements include the following:

  • Slight widening of bridge and roadway approach shoulders to improve safety.
  • Raising the bridge to meet desirable standard on vertical clearance over I-39.
  • Bridge approach roadway profile modification, resurfacing and pavement markings.

Schedule

Current (this year)

Future (next year and beyond)

Traffic impacts/detours

Grotzke Road will be closed at bridge location to through traffic during construction. Local traffic will be able to use County Highway X to County Highway CX to cross onto the other side of I-39.
