Southbound I-39/90 expansion to start this week, Madison to Edgerton
Motorists encouraged to plan ahead, be alert and drive with caution.
This week, crews will begin to reconstruct and expand Interstate 39/90 southbound from County AB, just south of Madison, to East Church Road, about two miles north of the US 51 interchange (Stoughton Exit 156) in Dane County. Nighttime single lane closures are anticipated during the first few weeks of construction, and will occur between 8 p.m. and 5 a.m. Monday through Friday. During these operations, traffic shifts are anticipated within these project limits to accommodate future traffic staging.
By mid-April, all Interstate traffic will shift onto the northbound side via crossovers, while the adjacent ten-miles of southbound Interstate is reconstructed and expanded. Two lanes of traffic will remain open in each direction, with northbound and southbound traffic separated by a median barrier wall. Please stay in your lane and follow the posted speed limits to safely navigate these areas.
During construction, all ramps will remain open at the County N interchange (Exit 147). Occasional nighttime ramp closures may occur and message boards will provide advanced notice of the overnight closures.
Local roads under I-39/90 (i.e., County MN, Drotning Road, County W and County B) are anticipated to be closed during the construction season for bridge work. Motorists must use alternate local routes during these closures. Access for emergency vehicles will be provided.
All lane restrictions and work operations are weather dependent and subject to change. Motorists are reminded to be alert, eliminate distractions when driving and do not tailgate.
The $41.4 million project is expected to be completed in mid-November 2019.
