I-39/90 traffic: be alert for crossovers in work zones

Updated: Oct. 23, 2017

Crossovers are located in various locations along Interstate 39/90 near Edgerton, Newville, and, most recently, Janesville. Motorists heading north (or south) on the Interstate will encounter crossovers, directing them to shift onto the southbound (or northbound) side of I-39/90 as crews reconstruct the opposite side of the Interstate. Two lanes remain open to traffic on I-39/90 (in each direction) during daytime hours.

Watch the below video to learn more about traffic crossovers along I-39/90, between Beloit and Madison.


For everyone’s safety, please:

  • Pay attention. Keep your head up and phone down when driving.
  • Give yourself room. Rear-end collisions are one of the most common work zone crashes, so do not tailgate.
  • Plan ahead. Leave early or map out an alternate route. Find the latest road conditions and work zone news at www.511wi.gov.
