Road construction

Work is ready to commence on the massive rebuild of Interstate 39/90 from Madison to the Illinois state line, with the next portion of work being the southbound lanes near Edgerton.

The state Department of Transportation said work could start later this week depending on the weather.

The stretch being worked on is about eight miles long, from East Church Road in the town of Christiana south to the Dane/Rock County line just east of Edgerton.

During the construction, nighttime single-lane closures are planned the first month, between 8 p.m. and 5 a.m. Monday through Friday.

About two weeks after construction starts, all Interstate traffic will be shifted onto the new northbound side, using crossovers across the median.

Two lanes of traffic will stay open in each direction, with a median barrier wall in between northbound and southbound lanes.

Ramps at Exits 156 and 160, both north of Edgerton, will stay open, but there could be occasional nighttime ramp closures at each interchange. Message boards will let motorists know in advance of closures.

Lake Drive under I-39/90 near Edgerton will be closed from mid-April to early September, so new bridgework can be built over the roadway.
