Temporary widening work is anticipated to begin next week on the southbound side of Interstate 39/90, between Madison and Edgerton, in Dane County. The project work limits are from County AB south to East Church Road (mile marker 154).
In conjunction with the temporary widening, crews will also widen four southbound Interstate bridges spanning local roadways within these limits, including County MN, Drotning Road, County W and County B.
Due to the bridge widening work, County W under I-39/90 is anticipated to be closed starting Thursday (June 15), and Drotning Road is scheduled to be closed beginning Thursday, June 22. Motorists must use alternate local routes. These roads are expected to be open in mid-September. County MN and County B will be closed at a later date, and message boards will warn motorists of the upcoming closures.
I-39/90 remains open to two lanes in each direction during peak travel times. Nightly single lane closures will occur on the Interstate weeknights from 8 p.m. to 5 a.m. within the construction project limits. All lane restrictions and work operations are weather dependent and subject to change. Motorists are reminded to be alert and drive with caution in all work zones.
The $12.6 million project is expected to be completed in mid-November 2017.
