I-94 (County N interchange to Airport Road)

Cottage Grove to Lake Mills, Dane and Jefferson counties

Project Overview

The Wisconsin Department of Transportation (WisDOT) will improve 9.6-miles of I-94 in Dane and Jefferson counties. The project starts just east of the County N interchange and ends just east of the Airport Road overpass.

This project will prolong the life of the I-94 pavement and structures until a future reconstruction and capacity expansion project can be implemented.

Proposed improvements:

  • Milling the existing asphalt surface, repairing the underlying joints, and placing new asphalt over the eastbound and westbound lanes of I-94.
  • Minor rehabilitation work is also planned for the bridges over I-94 at Baxter Road, Ridge Road, Oak Park Road, and County O; as well as at the eastbound I-94 bridge over the Koshkonong Creek.
