Bridge Replacement Project Underway on I-94 over Buffalo River

Motorists can expect to encounter occasional lane closures and minor delays along I-94.
Published: April 10, 2019

On Monday, April 8th, 2019, the Wisconsin Department of Transportation (WisDOT) began a bridge reconstruction project near the township of Sumner in Trempealeau County. This project involves the removal and replacement of four bridges along I-94 that run over County Highway NN and the Buffalo River. The new bridges will be widened to accommodate a future six-lane highway.

Kraemer North America, LLC is the prime contractor for the $10,000,000 project. Eighty percent of the project will be paid with federal transportation funds; the remaining 20 percent will be paid with state transportation funds.

Proposed Traffic Impacts

During construction, single lane closures will be restricted to off-peak traffic periods. Four lanes of traffic will be maintained for most of the project, and temporary median crossovers and bridge structures will be utilized as a form of traffic control.

Full closures of County Highway NN and the Buffalo River State Trail will occur throughout the project for critical overhead bridge work (i.e. demolition, girder placement). These closures will only be maintained overnight.

Construction is currently scheduled for completion by early October 2020.
